GET ON TOP OF LOFT INSULATION

Demand for insulation is through the roof as homeowners are desperately looking for ways to improve the energy efficiency of their homes. This month Bradley Hirst, Technical Services Manager at Knauf Insulation explains why your customer should install loft insulation to 500mm to ensure maximum savings on energy bills.

Top-up insulation or replace it?

If there’s already some mineral wool installed, assess whether it can be topped up or should be replaced. If it’s in good condition and has been correctly installed mineral wool insulation lasts for over 50 years, so it’s fine to insulate over the top. But if it’s been torn, compressed, fitted incorrectly, or disturbed so there’s gaps between rolls or the joists, it will need replacing.

Maximise performance

Under Irish Building Regulations, renovated roofs, including lofts insulated at ceiling level, must achieve a U-value of 0.16W/m2K.

For a typical loft, installing Knauf Insulation’s Loft Roll 40 or Loft Roll 44 at a depth of 300mm will meet these standards. But we know that the thicker the insulation is, the more effective it will be at preventing heat transfer. That’s why, housebuilders are installing loft insulation to a depth of 500mm in new homes. So to help your customers cut their bills as much as possible, advise them to do the same.
