What is Spray Foam Insulation?

Spray foam insulation is a rigid foam that is used in a wide range of applications, including commercial, industrial and domestic. In the past it has been used predominantly to insulate commercial freezers and large scale buildings, but it can also be used as an insulator on a wide variety of products including items such as domestic hot water tanks.

Spray foam is an insulation product that comprises of two compounds. These compounds are blown through hoses that meet at the spray gun combining the compounds into a single composite as they are sprayed onto the underside of the roof lining; felt, paper, boards etc, between the rafters.

On combining, the compounds create an exothermic reaction causing the liquid to expand filling all the gaps between the rafters. After the reaction has completed the spray foam insulation cures and sets creating an airtight barrier.

Where Can I Use Spray Foam Insulation?

For Lofts & Roofs

Traditional Fibre-based insulation holds dust and creates a bed for pests or rodents. It also shrinks and degrades over-time, requiring lifelong regular top ups. Either open or closed cell spray foam, applied between the roof rafters offers a clean and efficient process that helps to create a single climate within the home. Banishing cold draughts to the past, spray foam will stand the test of time and performs for life, guaranteed for a minimum 25 years.

New Build Roofs

When building a house, onerous building regulations make the insulation provision more important than ever. Traditional forms of insulation require an air-gap which takes up valuable room in the structural frame. Providing an air-tight insulation solution is time-consuming and uses valuable resources. Spray Foam overcomes this by offering exceptional thermal performance per inch, it’s around 5 times faster to install and complies with Building Regs.

Corrugated Roofs

Metal, cement fibre or asbestos corrugated roofs are common across the UK and are generally found on warehouses, factories, agricultural buildings and workshops. They are traditionally difficult to insulate due to the rippled surface and during winter months, they tend to condensate. Spray Foam Insulation is applied directly to the surface, bonding the roofing sheets to add structural integrity and will last with the entire life of the building.

Concrete Soffits

Many large buildings are constructed using poured or formed concrete because it’s quick, effective and structurally sound. Like many perimeter surfaces, concrete requires good insulation to seal the thermal envelope of the building whilst preventing heat loss. Spray Foam represents one of the best options to insulate concrete structures because of its speed of application and ability to adhere seamlessly to the substrate, providing durable performance.

New Build Stud Walls

Timber or metal frame studs require insulation between them to protect the thermal envelope of the building. Similarly to pitched roof insulation, the strict U-Value targets make the choice of insulation an important factor. Spray Foam is the perfect choice for maximising limited space and it offers a fast and effective air-tight solution. Closed Cell Foam is great for structural integrity and thermal performance, Open Cell Foam is best for soundproofing.

Cavity Walls

Many existing and new build homes in the UK are constructed using an outer and inner skin block wall with a cavity gap in between. With up to 30% of heat lost through walls, insulating the cavity is important to protect the building. Traditional materials like fibre or cellulose do not truly fill every area of a cavity wall void and over time, they shrink, slip and degrade. Slow rise injection foam insulation expands to completely seal the void and does not degrade over time.

Underfloor

Many homes or buildings suffer with cold draughts when there’s an uninsulated void. In some homes, underfloor sections can be accessed via an external or internal hatch, therefore, it is possible to insulate as a retrofit solution. In new build property, floor insulation is a vital part of the thermal envelope requirements. Spray Foam offers a great alternative to traditional materials and as an in-situ application, it bonds to the underfloor to provide lifelong performance.
