What is Spray Applied or Injected Polyurethane Foam?
Foamspray are experts in this spray insulation. Spray-applied or injected polyurethane foam is a chemically modified polyurethane foam, which can be applied to roofs, walls and ground floors to meet and surpass the insulation requirements of Building Regulations. In this respect, the process would be much in demand following the Governments move towards its target of zero carbon emission homes by 2016. A timetable is underway for the progressive tightening of Building Regulations Part L in 2010, 2013 and 2016.
What are the benefits of Specifying the Process
High thermal polyurethane insulation systems can be spray applied to the required insulation value. Applied as a liquid to roofs, wall and ground floors, it expands to create a superior insulation and acoustic barrier. The two component liquid system produces a highly-efficient blanket of insulation with the thermal conductivity of 0.023W/mK. It is particularly easy and effective to apply a wide variety of substrates and is fibre free. Its closed cell nature renders it very resistant to moisture ingress and grades are available which achieve both Class 1 and Class 0 fire rating when tested to BS476 Part 7 and Part 6 respectively. Furthermore, it has a very good track record in retrofit applications, both domestic and industrial/commercial. One of the most important aspects of spray-applied polyurethane foam is the fact that it produces a seamless blanket of insulation giving rise to product without joints. Any jointed system, including insulation boards, gives rise to a potentially weak point leading to a significant loss of insulation value. In a report carried out into the life cycle assessment of insulation materials, it was concluded the PUR foam can make an important contribution to the protection of the environment, especially through retrofitting of existing buildings.
