Do I need new windows? Try upgrading your insulation first with an easy retrofit

epc-ratingAs the temperature across the UK lowers homeowners begin to notice an unwelcome increase in energy bills as central heating use increases. Many homeowners may notice unusually high energy bills and attribute this to old windows allowing heat to seep out, in reality it could be that your insulation isn’t sufficient anymore at retaining heat in your home. The average cost of installing all new windows on a 3-bed semi-detached house is around £4000 according to The Eco Experts, but for a few hundred pounds you can retrofit insulation.

35% of the heat lost from your home is through the walls

By fitting external insulation on your home you can minimise this loss and in turn save yourself money on your energy bills. Another way to curb this loss could be through retro-fitting cavity walls with cavity wall beads. Specialist installers can blow beads through an injection gun into holes drilled into cavity walls. The tiny holes allow the beads to situate themselves in the wall, after being coated by an adhesive as they pass through the gun. As the beads are made up of 98% air, they’re perfectly suited to insulating your home and make a world of difference.

25% of your heat loss is from the roof

By applying just 100mm of insulation you can reduce the amount of heat that is lost from your roof by 75%. The massive reduction in loss of heat could save you a lot of money over the course of the years, especially if the loft is to be converted to house an additional bedroom. The most common type of private residential roof is a pitched roof which means many different types of insulation can be chosen to fit. One of the easiest ways to upgrade the thermal performance of your roof is to apply rigid insulation, such as Eco-Versal PIR boards or Kingspan Kooltherm, underneath the rafters. If you apply a vapour control layer too, this will ensure that your roof is protected from condensation.

When your home is well insulated you could apply for a renewed EPC. An Energy Performance Certificate (EPC) is given to every household bought and sold in the UK as a way of communicating what the bills are likely to be for the residence. Provided on a scale of 1 to 100, the higher number the lower the running costs. This can be a big factor in whether prospective buyers will be interested in your home so retrofitting insulation is one way to boost this rating and make your home a more attractive purchase.
