Spray Polyurethane Foam (SPF) in buildings
Spray Polyurethane Foam (SPF) can form a continuous insulation system, create an effective air barrier, and provide a moisture barrier in the building envelope. Products are extremely versatile and optimised by manufacturers to have excellent performance in different areas of a home or building. SPF can make homes more sustainable and comfortable. With SPF, builders can reduce construction costs, meet or exceed the stringent requirements of today’s building code.
It is important to recall that a certain level of indoor ventilation and air refreshment must be ensured if the building is insulated to a high level.
Residential buildings
SPF insulation offers multiple solutions for residential buildings
Wall installation in between the beams
SPF is used for both timber frame and masonry walls. The SPF is applied layer by layer to fill the cavity and reach the target thickness. Any type of structure can be sprayed.
SPF installed in between the rafters
The foam is sprayed directly onto the wooden deck or the membrane between the rafters. SPF is the best solution to save time and avoid any thermal bridges: the foam covers the whole pitched roof, including the rafters. Acoustic performance and airtightness are a huge advantage of this solution.
SPF installed on the attic floor or ceiling
Spray Polyurethane Foam under the face of the ceiling or from above in between the joists of the attic floor reduces condensation risk, thermal bridges and saves heating costs of unoccupied attic space.
SPF insulation on flat roofs
High-density foam perfectly suits for application on flat roofs. It is sprayed from the outside directly onto the concrete/masonry substrate with the recommended coating cover. In addition to its excellent thermal conductivity, its high compressive strength and resistance to moisture ensures its durability for decades (precautionary application measures must be taken: wind screens, maximum wind speed, etc.).
Internal insulation
SPF is also applicable from inside behind gypsum boards. It provides excellent thermal as well as acoustic performance, no thermal bridges, guaranteed energy savings and durability.
External insulation behind the cladding
SPF, in particular closed-cell, is applicable behind cladding of external walls of residential buildings. It provides excellent thermal performance, no thermal bridges, guaranteed energy savings and durability.
SPF injected in cavity walls
SPF is injected between two walls (wooden frame or masonry wall) to fill air space and give a better thermal performance to the wall.
Floors insulation
SPF with high compressive strength is applied directly on the concrete slab or gravel to cover the pipes and insulate the floor. A thin thickness brings significant benefits in terms of reducing energy consumption.
This solution provides a smooth finish and thermal performance in one. The foam is then covered by a concrete screed or a suspended timber floor.
Crawl space
Directly sprayed on the ceiling of the crawl space, the foam limits the risk of condensation and offers the possibility of a warm and airtight floor.
Commercial buildings
SPF insulation offers multiple solutions for commercial buildings
Roofs sprayed from inside
Spray foam is perfect for internal roof insulation thanks to its good adhesion, high thermal resistance, the fact that it is lightweight and speed of application. It is an excellent solution for existing buildings to reduce heating costs.
Flat roofs application
High-density foam perfectly suits for application on flat roofs. It is sprayed from the outside directly onto the concrete/masonry substrate with the recommended coating cover. In addition to its excellent thermal conductivity, its high compressive strength and resistance to moisture ensures its durability for decades (precautionary application measures must be taken: wind screens, maximum wind speed, etc.).
External walls
SPF is applicable behind cladding of external walls. It provides excellent thermal and acoustic performance, no thermal bridges, guaranteed energy savings and durability.
Internal walls
SPF is also applicable from inside behind gypsum boards. It provides excellent thermal and acoustic performance, no thermal bridges, guaranteed energy savings and durability.
