What is Spray foam insulation?

A Quick Introduction to Spray Foam

A liquid polyurethane is sprayed onto the surface you want to insulate and it expands within three to five seconds to form an airtight thermal and vapour barrier. When applied the foam will expand by a ratio of 1 / 100 to create a perfect airtight fit and eliminate all heat loss.

Where can spray foam be used?

Sprayed foam insulation systems offer numerous solutions for roofing, sound absorption and heating cost reduction depending on individual needs and budget. At I.S.F. Energy Control, we supply and install a series of foam insulation systems designed for residential, commercial and industrial applications. In addition to attics, it is well suited to metal structures (commercial / agricultural buildings).

What are the benefits of spray?

Overall the benefits are lower running costs for both heating and cooling. The results are immediate and will remain in place for the life of the structure.

With spray foam, there are a range of benefits.

It eliminates air gaps in the building envelope which are unavoidable with conventional insulation. This means eliminating condensation, drafts, noise and other external effects. Sprayed foam insulation will reduce the amount of pollutants and allergens that enter a building structure. Rain water is eliminated from entering the attic, reducing the risk of fungal growth and damage to the buildings structure. Closed-cell spray foam insulation offers the best U-value per inch of any insulation system available. Spray foam will add support and rigidity to ageing roofing structures such as "Bangor blue" slates to prevent sagging or slates slipping.

Is spray foam environmentally friendly?

I.S.F. Energy Control insulation systems are eco-friendly using renewable energy sources, such as caster, sugar cane. Using our products in your home or business will help reduce the emissions of greenhouse gasses (carbon footprint) into the environment such as carbon dioxide and methane. I.S.F. Energy Control insulation foams contain no H.C.F.C.'s, V,O.C.'s, or formaldehyde, they will not settle, sag or decay and there is no off gassing over time.

Does spray foam "settle" over time?

Sprayed foam will not sag, settle, or lose its U-Value over time unlike tradition glass fibre or loose fill insulation products.

Will spray foam cause the building to "weaken" in any way?

No. In fact, sprayed foam adds significant structural strength to any home or building to which it is applied. In many tests conducted, closed cell foam has doubled the racking load making your home more resistant to severe weather conditions.

Is spray foam breathable / permeable? And why is that important?

Non breathable / permeable insulation can cause a build up of condensation. Open cell foam is 90 to 96% breathable and is the most popular foam insulation at the moment for residential properties due to its cost effectiveness and energy saving factors. Where a vapour barrier is required, closed cell foam is specifically designed as damp proofing and a vapour barrier with excellent U values in a perfect air tight fit.
