What Is Spray Foam Insulation ?

Spray foam insulation is a flexible insulation system that can be used as an alternative to fibreglass, cellulose, foam boards, and other materials.

Also known as polyurethane foam insulation, it is poured as a liquid onto a surface where it absorbs air  and increases in size and thickness. Hardening into a solid material, it creates a shield that prevents heat leakage, and provides extra structural protection. Spray foam insulation can also be used to insulate roofs, attics, walls and floors.

Understanding the Two Main Types of Spray Foam Insulation

Spray Polyurethane Foam (SPF) insulation can be divided into two main types.

Light-Density Open-cell Spray Foam

The high yield of light-density spray foams makes it more cost-effective than other options on the market.

Yield is the measure of the expansion potential of foam. It is three to four times greater for light-density spray foam (100:1 vs 30:1) than medium-density spray foam. This high yield makes the product more cost effective by optimising the air barrier advantages of spray foam.

Medium-Density Close Spray Foam Insulation

Medium-density, closed-cell polyurethane spray foam insulations have an R-values of 6.7 per inch and 6.6 per inch respectively, which complies with regulatory requirements as the ideal insulating materials for flood areas.

Additionally, closed-cell foam provides an inherent air barrier with low permeability of moisture vapour and excellent water resistance. In building construction, the medium density foam provides unequalled strength for walls. The “closed-cell” description originates from the cell structure of the finished insulation material.

How Does Spray Foam Insulation Work ?

Spray foam insulation (SFI) is a mixture of liquid chemicals (polyurethane and isocyanate) which, when sprayed, expands into a foam which sets in an insulating sheet.

The two materials are concurrently sprayed from the tip of a spray foam gun during the construction process, allowing them to extend and create a protective layer of spray foam insulation over the target area.

Unlike traditional insulation materials, spray foam completely covers the structure, including  holes, openings, and crevices. It does not curl, sag or settle over the course of time. While completely insulating the entire surface area, it also serves as an impermeable barrier to air and moisture, even without the need for a separate vapour barrier.

What Are the Benefits of Spray Foam Insulation ?

Condensation Control

There are two types of spray foam insulation: closed-cell and open-cell. Closed-cell insulation is a more compact barrier to air and water vapour. The open-cell foam does not close completely, and is more like a sponge. Due to its chemical and air sealing properties, closed-cell spray foam prevents condensation that leads to the growth of moulds.

Mould Prevention

Both open-cell and closed-cell foam insulation prevent water from getting into the walls of the building. While both forms of foam reduce condensation build-up, the closed-cell spray foam acts as a shield against large volumes of water. The less water that flows into the windows, the less there is a chance of mould and mildew which cause health issues.

Energy Efficiency

Spray foam insulation seals the house, providing an airtight warm roof and loft system that helps keep the home warm in winter, and cool in summer, while minimising heating and cooling costs and thereby saving up to 50% on energy bills. This cannot be done with conventional insulation.

Spray Foam Is Eco-Friendly

During and after installation, spray foam insulation is non-toxic. The spray foam insulation we use doesn’t contain CFCs, HCFCs or other ozone-depleting materials. Studies demonstrate that spray foam insulation significantly decreases the impacts on the environment and energy in domestic, commercial, and industrial properties. Simply put, the benefits of using spray foam insulation far outweigh the effects associated with the manufacturing of raw products used for spray foam insulation. What’s more, spray foam can be sprayed onto an existing roof to prevent re-roofing.

Improved Air Quality

Spray foam insulation is of significant benefit for those suffering from asthma and allergies. It is a non-toxic alternative. No dangerous chemicals such as formaldehyde will be released into your house or workplace from the chemical blend. The ability of spray foam insulation to eliminate indoor allergens such as dust, mould, mildew, pollen and other contaminants, is a significant advantage. These allergens don't move through open doors and windows into your house or office, instead, they find their way into your walls. Air quality is often generally compromised by waste from pests, but insects and rodents are not drawn to spray foam, because it is not suitable as food or shelter. If you want insulation that reduces the effects of allergies and asthma, and minimises environmental exposure, then consider spray foam insulation.

Draught Proofing and Temperature Control

After we install spray foam insulation in your home, you will find your house cozier than ever before. Drafts will be eliminated from your home. The seal created by the installation of a spray foam would help to minimise cold and hot spots within the home, since holes are filled. Also, one of the greatest benefits of spray foam insulation is that it helps keep your house at a steady temperature, providing a warm and cosy atmosphere all year round within your home.

Air Tight

Spray foam insulation will create an airtight barrier that is twenty-four times less permeable to air than some other insulation. It outperforms other types of insulation, because it can extend and fill some crevices securely which might otherwise have been left uncovered. The resistance capacity of spray foam insulation is R-6, which happens to be the highest industry rating.

Long Lasting

If spray foam insulation is properly installed, it will not deteriorate over time. It can last for the lifetime of the house. Also, its application to roofs can last for more than 30 years, with sufficient long-term maintenance. Spray foam insulation adheres to virtually all substrates extremely well and keeps its stiffness once dry.

Add Strength to Building Structure

The strength of the frames that support the building determines how strong the building is. Most types of insulation do little to improve the ability of the building to stand up to the wrath of Mother Nature. Spray foam adds to the strength of building structures by ultimately becoming one with the surface on which it is sprayed, as it spreads and covers every hole and crevice.

Prevents Moisture

Moisture that gets into the walls of your home is mostly through the air. By air sealing it with spray foam insulation, you can reduce the amount of moisture that gets into your house, and stop mould and fungus harm that can result from the moisture.

Spray Foam Insulation Does Not Lose its R-Value Over Time

While there may be concerns with inadequate installation as some spray foam installations do not follow requirements, one of the main benefits of this solution is that it does not lose its R-value over time. Open-cell products offer an aged R-value of 3.5 per inch, while closed-cell products can offer up to 7 per inch of aged R-value.

Relatively Quick and Easy to Install

In general, spray foam insulation is about five times faster to install, compared to traditional materials such as PIR boards or fibre-based insulators, depending on the total size of the area to be insulated and the thickness required. Consequently, spray foam insulation makes construction work faster, and the space is instantly available to use as the insulation is completed quickly.

Are There Potential Problems With Spray Foam Insulation ?

There are several challenges associated with spray foam insulation, though not directly caused by the product itself. These problems include:

1. Spray Foam Insulation is Relatively Costly

Other materials are likely to be cheaper, unless the area being insulated is difficult to access.

2. Spray Foam Insulation is Difficult to Remove

Spray foam insulation can be incredibly hard to remove. If something goes wrong with the installation or afterwards, the cost of removing spray foam insulation can be high, since it has stuck to the substrate. To solve this issue, some installers give a removal guarantee.

3. Spray Foam Insulation can Cause Cracks and Gaps

Not all so-called professional installers are trained to carry out spray foam insulations. So, when improperly fitted, spray foam insulations will break the substrate and pull it out. If this occurs, the thermal output would be greatly affected.

4. Spray Foam is Frowned Upon by Mortgage Providers

Some mortgage firms do not like spray foam insulation, so before you install it, it’s advisable to inform your mortgage providers first.

If they're okay with it, you still need to consider buyers should you decide to sell your house in the future. You need to consider whether the mortgage service used by a potential buyer will be okay with it.

5. Spray Foam Insulation can be Poorly Installed

Poor installation of spray foam insulation can happen if the installer hasn't done the correct calculations to determine how much insulation is needed and if too much or too little foam is applied.

However, the good news is that the problems with spray foam are generally infrequent and easy to overcome with proper planning and implementation.

How Does Spray Foam Insulation Compare With Traditional Insulation ?

Understanding the main distinctions between spray foam insulation and conventional insulation is very important if you are considering the type of insulation to use for your property.Traditional types of insulation include fibreglass insulation, cellulose insulation, Celotex insulation, and Rockwool insulation.
Spray Foam InsulationTraditional Insulation
Certain forms of spray foam require water to flow through it in case there are leaks, allowing you to fix any damage quickly.Traditional insulation could hold water that could theoretically destroy your house, as well as damage the insulation function. Worse, the retained water can lead to the growth of moulds.
Spray foam insulation is fully perfected to ensure that your home follows today’s building standards and lasts for life.Traditional insulation materials in your state might struggle to meet ever-changing building regulations.
Spray foam insulation is a modern material used for more than 25 years.Fibreglass is an ancient product and cellulose is nothing more than recycled newspaper. 
Insulation from spray foam is thick and airtight. The substance stretches to cover cavities, gaps, and crevices in the building, ensuring that no air escapes.fibreglass allows air leakage which results in moisture which is detrimental to fibreglass insulation efficiency. When fibreglass gets wet, mould and mildew start to grow.
Spray foam doesn’t lose its R-value over its lifespan.Fibreglass loses R-value over time.
Many spray foams (such as Icynene) do not contain formaldehyde, HFCs, HCFCs, or HFAs, and, once installed, does not release harmful emissions.Most fibreglass contains formaldehyde and can emit fumes of formaldehyde to your home.
Spray foam adds to the integrity of your structure. Closed-cell foam gives the walls and roof of your house up to 250% racking energy.Traditional insulation adds zero strength to buildings.
Spray foam insulation can last for over 80 years.If the fibreglass remains dry, you can expect it to last for 10–25 years.

What Are the Main Building Applications for Spray Foam ?

house spray foam insulation

House Insulation

Spray foam insulation sets very hard. When it's set, it's not compressible, which ensures it can help strengthen the foundation of the property. Spray foam is a perfect way to plug holes and cracks. It has better energy efficiency than other insulation products because of its high R-value and it offers outstanding insulation. Closed-cell spray foam also removes water vapour, thus forming a barrier to moisture. This means it will help avoid issues with moisture and leakage, dissuading moulds from growing.

cavity walls spray foam insulation

Cavity Walls

Spray foam insulation can be added to any surface to prevent draughts and increase the quality of the building, making it suitable for cavity walls. Since the reactive two-component mixture expands once blown, spray foam insulation is the easiest method to apply. Injected closed-cell foam systems not only provide superior cavity insulation but also have adhesive bonding properties, which can improve the structural stability of any treated structure. It also helps bind the inner and outer leaves to give the building strength.

window spray foam insulations

Window Insulation

One of the most common applications for expanding foam is windows and doors. When not well-sealed, windows can be a major source of heat and energy leakage, and an obstacle to keeping a home cool in warmer climates. Foam insulation, typically in the form of spray polyurethane foam (SPF), acts to build efficient air barriers around windows by stretching the distance between the window and its frame, or between the frame and the wall, and then solidifying into a vapour-tightened, insulating seal.

underfloor spray foam insulation

Underfloor Spray Foam

There are times when insulating below your floor makes sense. For example, in cold climates, the insulation of the floor above the crawl space is often more energy effective than insulating foundation walls. Under-the-floor insulation is typical in crawl spaces, but is prone to the common challenges mentioned above. A safer solution is to insulate the crawl space with spray foam. Spray foam insulation can be added to the crawl space walls and the crawl space floor can be coated with a special moisture resistant foam insulation.

Suspended Timber Floor spray foam insulation

Suspended Timber Floor

Certain materials are made very suitable for suspended floor insulation in the home or commercial building due to their lightweight and robust design. Open-cell spray foam insulation is a good match because of its completely breathable properties and its design fit for each use. It prevents cold floors and drafts and contributes to significant thermal comfort. Simply stated, the perfect insulation system for suspended timber floors is spray foam.

Dry Lining Spray Foam Insulation

Dry Lining Insulation

Icynene Classic is the ideal insulation when new dry lining studs are installed on the inside of the exterior wall and the foam will expand to 100 times its original capacity to close and insulate each crack and crevice and remove the cold bridging of the timber or metal grips. Ifspray foam insulation compacts air securely onto walls and spaces and can be smoothed in such a manner that dry lining can be quickly placed. The mixture of our spray insulation and dry lining totally removes cold spots and draughts with a neat and smooth finish. It will also offer better acoustics and will not sag.

wall spray foam insulation

Wall Insulation

Most houses, including new builds, may not have adequate insulation. They need spray foam insulation in their walls. Spray foam is usually sprayed as an expanding barrier. It not only provides a superior insulation system when used as continuous insulation over wall sheathing, but also serves to improve the rest of the wall assembly as well. Medium density spray foam can be installed reliably and at very controllable thicknesses. That means it provides a flat and consistent surface ready to be cladded.

flat roof spray foam insulation

Flat Roof Insulation

Since the advent of flat roofs, it’s been a problem for builders and homeowners alike. Flat roofs are difficult to waterproof, difficult to clean and difficult to insulate. Having an unventilated area and sealing the area with 4 to 5 inches of spray foam is now both simpler and more effective. Foam roofing is expected to achieve 30% or more energy savings compared to alternative roofing systems. It's very likely the roof would have paid for itself within just five years.

ceiling spray foam insulation

Ceiling Insulation

Using spray foam insulation will give you significantly lower energy costs and minimise sound transmission in your cathedral ceiling. Your roof will now have a smooth air barrier which will conserve enormous amounts of energy along with a strong R-value. Your roof can now significantly limit sound transmission and deter rodents. Your household will also experience significantly improved air quality.

Conservatory spray foam insulation

Conservatory Insulation

If your conservatory is too cold in the winter and too hot in the summer, you can say goodbye to intense heat, unbearable brightness, glare from the sun and the winter chill, typically associated with a conservatory. Avoid this with an insulated conservatory roof from Ifspray. Enhance your conservatory with spray foam insulation so that you can make use of it all year round. Save money on the heating bills by using advanced conservatory insulation to maintain heat and eliminate draughts.

parking garage spray foam insulation

Parking Garage

Spray foam insulation solutions are the best choice for insulating floor slabs in parking garages and the interior of concrete ceilings. Seamless, spray-applied and completely adhered, the clips are removed and quickly fitted. Long lasting, energy saving, with optimised thermal barriers, spray foam is the most affordable and effective solution on the market. Multifamily builders and estate managers welcome closed-cell spray foam to insulate parking garage ceilings. The energy efficiency, and moisture and condensation management of closed-cell spray foam outweigh all conventional applications.

pipe spray foam insulation

Pipe Insulation

Many homeowners are well aware that their walls, floors, roofs, and basements should be insulated, but one aspect frequently overlooked by homeowners is their drains. Pipe insulation can avoid the freezing and bursting of your pipes, which can create a number of issues in your house. Insulation of the pipe with foam spray is typically used in crawl spaces or similar places where freezing is very risky. In mild climates, it works well for this reason. In addition to avoiding freezing and bursting, insulating pipes can minimise heat loss in hot water pipes. This will help to increase water temperatures by 2–4 degrees and can help you save on energy costs so you can shut off the water heater.


External quality, closed-cell foams of high density can be used on nearly every roof. The foam is applied by spraying on a smooth, monolithic sheet insulating and fully covering all joints, bolt heads, fastenings, and so on. Spray foam roof insulation not only protects your property from the cold, it will also reduce the amount you pay on your power bills.

Shed Insulation

Sheds can be intensely cold and damp during the winter months, whether they are made of wood or concrete, or very hot and humid in the summer. Condensation will build up against the ceilings and trickle or drip down onto the contents of the shed. Spray foam insulation will help keep the interior of the shed at a relatively steady air temperature throughout the seasons. Spray foam insulation is by far the best insulating medium for buildings, including sheds. Spray foam insulation is the recommended insulating agent for any concrete construction in the UK and in the EU.

external spray foam insulation

External Insulation

Spray foam will fit perfectly between the edges of any sheathing you already have on the walls outside. Exterior foam insulation systems require the addition of a rigid foam insulation (polyisocyanurate, EPS, or XPS) between 2 and 6 inches on the outside of the wall framing. To avoid water intrusion, the window openings, door openings and the edges of the roof are measured, and a finish siding is applied.

loft spray foam insulation


Icynene spreads, filling all cavities and voids, totally preventing leakage and infiltration of air. In both new builds and existing houses, the Icynene spray foam insulation system is the most suitable type of insulation for your loft and attic areas. Icynene can also be installed on horizontal attic floors and can offer more than 50% energy efficiency in all conditions, more than any other insulation in the industry. When applied to roof rafters, it balances the loft temperature with the rest of the house. This minimises the issue of warm air interacting with cold air to form condensation.

Timber Frame Construction

The timber frame structure style does not lend itself to the thermal insulation requirements of contemporary housing and building codes. Fortunately, the spray foam insulation provides many insulation choices of high quality. Buildings with spray foam insulation in the UK are at least 50% more effective in avoiding energy loss through air infiltration. Also, spray foam insulation helps to protect against mould and mildew growth and wood decay. Icynene spray foam can be readily added between the timber frame structure to provide a tightly sealed airtight structure that does not rot or settle with time and will retain a high level of efficiency over the lifespan of the building.

interior wall spray foam insulation

Interior Walls

Do you want odours to be a thing of the past in your walls? Do you want to bring quiet into the interior of your home? Installing insulation in your interior walls can be of great help. When people talk about insulating walls, they generally think of the outside walls to make their home warm. Ifspray can install injection foam from inside your home without having to tear down the current drywall. Our team of experts will cut holes into the stud cavities of the wall, so that they can install the injection foam. We will clean up any mess after us, and patch up the wall where the holes have been drilled. Then a final polish would need to be given and the wall repainted. When you are in a position where your drywall is down and the wall cavity is uncovered, then open-cell spray foam can be used in this case. Get in touch with Ifspray today for more information.

Floor Insulation

Spray foam insulation prevents noises created from inside a building from entering the floors above, below or into adjacent rooms. Using hair dryers, telephones, office computers, printers, washing machines, laundry dryers, blenders, juicers, coffee grinders, televisions (for music and sports), flushing toilets, running baths, walking on the upper floors and playing and performing on a musical instrument are just a few kinds of noise that are often created in a system. These noises can be significantly reduced by spray foam insulation. Spray foam insulation limits the propagation of airborne noises by covering and closing any gap and crevice through which these sounds can pass. It is both robust and packed with millions of minute air bubbles which not only withstand the sounds of the concrete and wooden elements, but also prevent the immediate sound transmission through the floor.

What are Spray Foam Insulation Typical Costs ?

Spray foam insulation costs more than conventional forms of insulation, such as fibreglass. Spray foam is not the cheapest insulation option, but it is the best kind of insulation on the market.

Without a professional surveyor visiting your property to provide you with a free customised no-obligation quote, it is difficult to offer a flat price online.

That is because the quality of spray insulation differs greatly based on various variables, from job to job. The total cost of installing spray foam insulation varies widely, depending on the spray foam form and thickness.

The cost of the spray foam is usually calculated in square metres. Insulation of open-cell spray foam usually costs between £40–£70 per square metre. Whereas the more expensive and effective spray foam for closed-cells costs £50–£90 per square metre.

These are statistics from our own study and experience in the business.

Sure, insulation from spray foam is fantastic and works better than its alternatives in the market.

Homes insulated with spray foam can be listed among the most effective and comfortable homes. We have carried out lots of insulations in UK homes and can assure you that, when spray foam is properly installed, it outperforms fibreglass.

Icynene spray foam insulation, unlike other non-conventional insulation materials, does have BBA clearance and also complies with building regulations.

There’s no doubt that, based on pure R-value, spray foam is the perfect insulator. Yet selecting the right insulation for your particular property isn’t as easy as finding the one on the package with the highest R-value.

You will need to weigh crucial considerations such as the amount of room in your attic, the environment in your city, possible safety risks and, most importantly, your total budget.

Yes, you can. If you believe that DIY spray foam insulation kits are perfect for your needs, do your homework and, if possible, speak to people or get advice from people who have used it.

Only after familiarising yourself with all the possible advantages and drawbacks of the many available DIY spray foam insulation kits, should you go down this path. Although, ideally spray foam insulation should be installed by a specialist because it contains toxic chemicals that, if used incorrectly, will potentially affect the structural integrity of the building.

Open-cell polyurethane spray foam with noise suppression works well and is similar to fibreglass batten insulation. The open-cell, light-density spray foam insulation by Icynene has natural sound-absorbing properties that tend to make it soundproof.

Spray foam insulation can last for more than 80 years.

The benefits include the prevention of air escape, mitigating heat loss by an airtight lock, maintaining home energy conservation, minimising seasonal energy costs, a higher R-value than most other installations, and decreasing moisture accumulation.

The drawbacks are the high expense, initial cost and maintenance that are well beyond some homeowners’ expectations. It also takes time to set.

The other drawbacks of spray foam insulation do not come from the substance itself, nor from the people who make it. Owing to a lack of training, expertise and know-how, unlicensed insulation installers and unprofessional teams may have unsatisfactory results.

The product is as successful as the installation process. So, make sure of this when considering a company for spray foam insulation.

Water leaks in concrete are common in ageing basements. One of the easiest ways to avoid water leakage is to use spray foam insulation because the foam can extend through the holes and help deter potential leaks.

Yes, completely. If you insert spray foam insulation in a building, a thermal barrier is needed. That is what separates it from the spaces that are occupied. When there is a fire in the house, a thermal shield protects the spray foam from the flames.

Yes, spray foam insulation can insulate your water pipes, attic or crawl space. Spray foam helps protect water pipes from cold temperatures. It is also flood-resistant, making it best suited for use around water pipes.

Glass wool allows amplification of sound; non-porous spray foam does not. Spray foam insulation is an insulating foam that is sprayed with a machine.

Spray foam insulation can be sprayed on concrete slabs and walls. Even the smallest cavities can be lined with spray foam, providing an efficient air barrier.

Spray foam is resistant to heat, but is also typically only added to external walls to be coated with an internal coating. If you don’t have insulated or thermopane windows and insulated garage doors, insulating the walls won’t have as much benefit in maintaining the garage heat.

Unless your roof does not have a felt or membrane (common in older houses), then the Ifspray team can add a membrane before spraying. Spray foam roof insulation is then sprayed straight onto the surface until it is set up.

The improved HVAC efficiency, lower bills for heating and cooling, increased convenience, no more ambient noise, ice safety, and healthier indoor air are some of the ways you benefit from spray foam insulation in your loft.

Spray foam insulation is also an investment and will yield dividends in just three years of deployment. In the first year alone, consumers should expect a return on investment of 41%, with electricity savings of almost £2,000 per annum.

Yes, most installers provide funding solutions from their own company or a contractor with whom they associate. In certain cases, a better choice is funding directly with a spray foam installer.

Radiation happens as heat waves pass through the air and ultimately are absorbed by a substrate. It’s the reason the heat of the sun hits us through the solar system from so many millions of miles away.

Only a vacuum, air or a translucent substance may induce radiation. It means that spray insulation, like most solid objects, prevents the radiation from bringing heat into your house.

Insulation using spray foam does not encourage mould. And unlike metal and wood, spray foam does not crack, decay or rust over time. This ensures that an area correctly sprayed with foam insulation can never become a source of food or shelter for moulds.

Properly installed, spray foam insulation does not deteriorate. It will last as long as your home lasts.

Mice can chew straight through the usual spreading foam, but there are formulae that protect against insects and rodents.

It is safe to spray foam over windows and doors. But actually, it can push the jamb inwards, making it impossible to open them. Prevent this by using minimum foam. It is formulated to fill the space around windows and doors without excessive expansion.

When exposed to water, open-cell spray foam insulation will eventually dry out entirely. Furthermore, since spray foam is not a “food” for moulds, there is little danger that mould will become a problem even if it gets wet. Closed-cell foams don’t trap water either, which is very useful in flooded environments.

Do not use spray foam in areas too close to electrical boxes and areas too close to light boxes in the roof. Spray foam should also not be used to insulate areas near recessed canister lights at the ceiling level.

When used indoors, spray foam can be left uncovered. Spray foam that is exposed to sunlight will deteriorate after around a year.

When used elsewhere, such as an attic, transparent spray foam insulation can be left uncovered, but not in the living areas in the home.

Depending on the product and site conditions, a complete cure can be achieved within a time span of around 8 to 24 hours. It will normally take 5 to 60 minutes for the foam to get tack-free. The curing process can be improved by releasing a mist of water on the soil or/and between layers of the foam.

The thickness of spray foam really depends on where it’s being sprayed and what you’re aiming to achieve. Generally speaking, open-cell spray foam is commonly advised to be 6 inches on a roof deck or ceiling, and 3 inches in walls.

Since spray foam is an air barrier and insulation, it prevents the passage of air pressure and moisture. Regulations require open-cell spray foam to have a vapour barrier installed. A product must have a permit rating of 1.0 or less in order to be considered a barrier to vapour.

Closed-cell foam has a higher R-value, usually around 6.0 per inch, than open-cell foam. This higher ranking increases the use of closed-cell foam to hold the heat in or out of a system. The R-value of open-cell foams is about 3.5 per inch.

Yes, closed-cell foam destroys mould. It burns it. Moulds cannot withstand the exothermic heat and the encapsulation that ensues.

When choosing spray foam for your house, make sure you are using a reputable company. Spray foam needs to be correctly applied to be successful. Poor application will lead to some mess, loss of operation and a failure properly to adhere to surfaces. You can choose a reliable spray foam installer by reading reviews from other customers.

Not all spray foam is the same and each one needs to be applied to a specific thickness. So, read the product spec to make sure you get what you’re planning, and ask questions if in doubt before you hire an installer.

When sprayed, spray foam has an odour and must be used carefully. A good contractor knows this and will take appropriate precautions. Ask your potential contractor about the precautions they take. Make sure that you are satisfied with the answers you get before you choose the company.
