Spray Foam Insulation Costs

How much does it cost to install spray foam insulation? The reality is that spray foam insulation is more expensive than traditional methods of insulation. Spray foam may not be the most affordable insulation solution but today it is definitely the best form of insulation on the market. 

Without a professional surveyor to inspect your property to give you a quote, it is difficult to give a flat price online. This is because the cost of spray insulation varies significantly depending on different factors. 

This guide will, however, tell you all you need to learn about the factors that determine the cost of spray foam insulation in the UK.

Average Industry Cost

Insulation of the spray foam is more pricey than other insulation types. The cheaper of the two types of spray foam is open-cell spray foam. Insulation of open-cell spray foam usually costs about £40 – £70 per square metre. While the more costly and effective spray foam for closed cells costs £50 – £90 per square metre. 

The lower cost is for reinforcement of a thin foam sheet, and the greater price for a thicker layer of insulation. Closed-cell spray foam insulation is significantly more expensive than open-cell insulation. Installation difficulty, type of roof, and any required repair work will also affect the cost.

The IfSpray Cost of Spray Foam Insulation

The above-mentioned costs are industry averages as of 2019. IfSpray can, however, provide quotes for the installation of spray foam insulation at rates lower than those industry averages.

What are the Things to Consider when Looking at Spray Foam Insulation Prices ?

It’s never easy to estimate the cost of a spray foam insulation system. Two customers who go to the same service provider rarely get the same price. This is simply because a lot of different factors contribute to the overall costs. That’s why at IfSpray we can help you with quotes that are specific to your situation and the variables that impact them. Some of the factors influencing price include:

  • How much work is needed to complete the installation
  • Areas that need to be sprayed, including accessibility and size 
  • Specific products selected 
  • How much spray foam is required 

In short, as more factors are considered, you can expect prices to rise in conjunction with the installation process itself; spray foams with an average 40mm thickness have a cost baseline of around £27 per cubic metre. That doesn’t take into account any of the aforementioned factors, however, or whether or not you may need a thicker or thinner layer to more efficiently insulate your building’s area/s.

Type of Insulation

Spray foam insulation is of two types. The first is open-cell spray foam, the most common alternative, a breathable material capable of expanding and filling a large variety of places. Closed-cell spray foam insulation is usually used with the metal frame structure in vehicles and buildings. The cost can also be greatly affected depending on your choice of open-cell or a closed-cell  spray foam, so make sure that you know which one is right for you.

According to the International Association of Certified Home Inspectors, interior spray foam can last over 8 decades. However, things like water damage, punctured surfaces, sun exposure, and improper application can affect this lengthy lifespan. Inspecting the foam insulation now and then is essential to ensure it is holding up.

Spray foam insulation will actually reduce mould hazards. Mould growth on spray insulation is very unlikely to form. That being said, mould is still likely to form in places where humidity and precipitation are high. If this is the case you would need to call a professional mould removal specialist.
