Injected Foam Insulation

Foam injection insulation is like a single can of foam insulation that you can buy at home, but it refers to a much larger scale and a process with greater efficiency. Foam injection insulation is probably the best choice for modernisation to avoid damaging the wall. Injection spray insulation is not identical to spray foam insulation, although both materials look the same.

How Injected Foam Insulation Works

To understand how injection foam insulation works, it helps to understand the heat flow which includes three basic mechanisms: conduction, convection, and radiation. The heat flows from warmer to cooler areas until there is a temperature difference. The heat loss is also proportional to the speed of the moving air, the amount of moisture present, and the temperature difference between the heat source and the air itself.

Injected Foam Installation

Injected foam insulation is installed exclusively in closed cavities of existing walls. This process may seem like a mess in your home, but injection foam can actually be applied from the outside. Spray foam insulation is mixed in the trailer before assembly. When the resin mixes with foam and water, it turns into foam insulation that looks like shaving cream (in terms of consistency). 

The injection foam is mixed with the trailer and flows through the hose with the nozzle outside. If the nozzle is in the hole, the foam can be pumped into the cavity. After injecting foam insulation into each dowel cavity, the holes are filled with foam cork, and the lining is replaced. 

The injected insulation foam is sprayed in liquid form and expands very slowly. Due to the slow growth of the injection foam, even the smallest holes and cracks can be filled. Injection of closed cells takes longer because it must be done in smaller parts at the same time; it has a higher R value than injectable foam with open cells. 

Our experts at BrandXXX know exactly what you need to do in order to give your home the perfect foam insulation. We spray the injected foam safely and precisely between all of your wall posts. After injecting foam into the cavity walls, we leave enough time for it to harden. Then, we apply a layer of putty on each hole to seal it.

Advantages of Spray Foam Insulation

Heat Storage

Injected polyurethane foam helps reduce heat loss and draughts; this means you can use less energy to get a comfortable temperature in your home.


The injected foam insulation is extremely versatile and offers a unique range of properties, including excellent energy absorption, multiple impact resistance, thermal insulation, buoyancy, water and chemical resistance, exceptionally high strength-to-weight ratio, and 100% recyclability.

Best Insulator

Established products often prove difficult to process due to the uneven inner surface of the stone outer sheet. This can lead to “dead spots” (non-isolated areas), the size of which can vary. This obstacle is instantly overcome by using foam spray insulation. Due to the fact that it is 99% waterproof and extremely rigid, it is also the best insulator per thickness on the market today.

Successful History

Injection molded foam insulation is the insulation of choice for walls due to its long history of success, extensive testing and certification, unique non-toxic properties, and the ability to provide full insulation in one application.


  • According to energy saving estimates, 25% of the heat loss in the house passes through the roof, 35% through walls, and 25% through air leaks or draughts that come through the wall cavities and attic. 
  • Expanded polypropylene (EPP) is an extremely versatile closed cell foam that offers a unique range of properties, including excellent energy absorption, multiple impact strength, thermal insulation, buoyancy, resistance to water and chemicals, extremely high strength-to-weight ratio, and 100% possibility of being recycled. 
  • It is argued that around 30% of heating costs can be saved by insulating cavities in the walls, saving over PS100 per year on a medium-sized house. 
  • Spray foam saves up to 90% of heating energy. 
  • This obstacle is immediately eliminated by the use of foam for diaphragm walls. It is not only 99% waterproof and extremely rigid, but it is also the best insulator for thickness on the market.
