Counting the cost of insulation - Advertisement Feature

Insulation is the most single important element for energy efficiency, and a key element in reducing energy bills. There are several reasons why it is important to install the correct insulation

• Un-insulated walls and roofs are letting as much as 60% of a home’s heat escape, which equates to a lot of wasted energy and increased emissions.
• Savings can be made on heating bills - cavity wall insulation can result in savings of around £115 a year, loft insulation saves around £150 a year and by installing draught proofing around doors and windows, savings of around £25 a year can be achieved (according to the National Insulation Association).
• Savings in carbon emissions through installing polyurethane spray foam insulation - at rafter level, you can save between 1050 and 1530kg CO2 per year; cavity wall insulation saves between 1000 and 1240kg C02 per year, depending on the size of the property and fuel type used.

WALLTITE®, from BASF Polyurethanes UK have been working closely with the BRE to continually find ways to improve thermal performance and reduce carbon emissions in UK homes.  One example of this is the Green House Project which involved Huntingdonshire District Council identifying two homes in radical need of improvement.  Using easily affordable products and suppliers, the results from the BRE showed how simple it is to:

• Reduce carbon emissions by 75%
• Improve SAP scores and EPC ratings
• Reduce energy bills

Central to these results, WALLTITE has provided a thermally efficient, seamless airtight solution in two vital areas. WALLTITE® CL100 spray foam insulation was injected between the rafters to eliminate air leakage and help control the movement of vapour and moisture throughout the building, reducing energy loss in line with Part L.  
In addition, existing cavity fill in the external walls was replaced with WALLTITE® CV100 cavity injection insulation, to maximise the thickness of wall insulation, seal the house from draughts around window and door frames and reduce carbon emissions for the life of the property.  In addition, the closed cell structure of the polyurethane foam provides resistance to moisture ingress and is not affected by mould or fungal growth. 

Key benefits:

• Versatile for all types of building and profile
• Overcomes thermal bridging
• Prevents surface and interstitial condensation
• Eliminates air leakage and air infiltration
  Resistant to moisture
• Lightweight
• Consistent performance over the life of the building

As part of the Climate Change Act to reduce carbon emissions within the current housing stock by 2050, the Green House project shows how simple, easily affordable improvements can be made to existing properties to work towards and meet these challenges head on.
