Trusted Insulation Contractors in Ashford

Always use personal protective equipment, avoid all contact with skin and eyes and do not inhale the vapours of the hardener. Before opening the resin, unscrew the bung slowly to release the gas pressure in the drums. While spraying, always work with adequate ventilation. Protective gloves and face masks are mandatory. When atmospheric levels may exceed the occupational exposure limit (PEL or TLV), approved air purifying respirators equipped with an organic vapour sorbent and particulate filter can be used as long as appropriate precautions and change-out schedules are in place. Persons with known respiratory allergies must avoid exposure to the A component.

Our polyurethane foam roof and wall systems have been tested as an air barrier at an application of 50mm thickness. Once applied, our roof and wall systems are fully-adhered and do not allow air to flow around, behind or through the insulation system. Most open-cell foams have not been tested and therefore do not qualify as air barrier systems. Open-cell foam products require an application of up to 125mm to control air leakage.

Spray-applied closed-cell polyurethane foam is the only insulation material that adds structural integrity throughout the wall system. Testing shows spray-applied polyurethane foam insulation between wood- and steel-stud wall panels, increases rack and shear strength, two to three times compared with standard timber frame components with glass fibre insulation, when sprayed onto gypsum wallboard, and increases racking strength when sprayed onto oriented strandboard (OSB). Closed cell foam injected into a cavity, has enough strength to bond two leaves of a masonry wall together, in situations where the existing wall ties have failed.

Our polyurethane technologies are formaldehyde-free formulas that emit no volatile organic compounds (VOCs) and use zero ozone depleting blowing agent technology. Plastic building products, including polyurethane foam, use less energy from all sources than alternative products during production. Spray-applied polyurethane foam insulation saved 3.4 trillion BTUs in manufacturing energy over glass fibre in 1990. Our systems also increase building energy efficiency and reduce waste.

No. Spray foam should not be applied non-breathable roofing felt regardless of type in line with building regulations requirements and good building practice. Such membranes behave as vapour barriers. A vapour permeable slide should be used to maintain a 50mm ventilation void between the insulation layer and roof membrane.
