Icynene is the only foam on the market to have achieved BBA, ETA and BDA certifications and has been successfully tested and certified for applications directly to the underside of breathable and non-breathable roof membranes and felts. It has achieved BBA certification for this application. Icynene absorbs the lowest amount of moisture and has the highest level of vapour resistivity of any foam on the market.
control air leakage
For years, the performance of insulation has been gauged by its U-value alone. The truth is higher U-value doesn’t mean better consumer value – unless air leakage is controlled.
Computer simulations such as REM design and DOE4 have proven that air sealing your building will out-perform the same building with a higher U-value and excessive air leakage. Insulation that bonds to framing and sheathing helps minimise air leakage, providing an effective air barrier system.
the law of diminishing returns
It’s important to have a reasonable amount of U-value in the building envelope. However, the more you insulate a building, the more difficult it is to save money by increasing U-value alone.
The first few inches of insulation will always be the most effective in terms of saving energy.
Icynene provides control of air leakage and greatly assists in resolving the associate health and economic concerns. Thermal performance, air quality, energy consumption, sound attenuation and building durability are all negatively affected by poor insulation resulting in uncontrolled air leakage.
We use build desk approved software to work out any U-Value/condensation risk analysis requirements you have.
Working in partnership with Greentherm Solutions Ltd, we offer an RIBA approved CPD presentation which covers an introduction to the many uses of spray foam insulation as an alternative to more conventional forms of insulation while demonstrating the benefits of its use as a method in achieving U-Value and Air tightness requirements. The presentation focuses on control of air leakage and moisture vapour transmission with reference to Part L & F of the Technical Guidance documents.
