Safeguarding Health

Demilec spray foam can safeguard your family's health, protecting your loved ones from unwanted noise and the dangers of radon gas.

Air Leakage

Prevent air from leaking out of your home to reduce your heating and cooling cost. Improve the comfort of your home, and the overall indoor environment. 

Spray foam insulation can be applied throughout your home. Attics, crawl spaces, basements, ceilings, exterior foundations as well as interior and exterior walls. 

Radon

Radon gas is an invisible killer. In the UK, it causes more deaths than drink driving and accidents at work combined.

Demilec closed cell foam is resistant to radon gas. Offering perfect air-tightness under the foundation slab. It's also insulating. Applied to at least 32mm, it meets all insulation, air-tightness and vapour barrier requirements. In fact, at 32mm it's 11 times more efficient than a 6mm polyethylene membrane. 

The perfect continuity of Demilec closed cell foam seals the foundation wall joint to the foundation, leaving no seams. No sealant, tape, or cutting material is required. 

Home Comfort

Outdoor noise, allergens, pollutants and inconsistent temperatures are all contributing factors to an uncomfortable home.

By installing spray foam insulation, you can reduce outdoor noise and help to minimize dust or allergens from entering the home. By reducing air leakage, spray foam also keeps an even temperature throughout the home - and can also contribute to reduced heating and cooling bills.

Not only can spray foam help inside the home, but it can improve the structural strength and create a barrier against floods. 

Why Spray Foam?

Eco-friendly, innovative and with exceptional energy savings, spray foam offers enduring advantages over fibreglass
