Heat rises, and in an uninsulated home a quarter of your heat is lost through the roof. Insulating your loft, attic or flat roof is a simple and effective way to save that waste and reduce your heating bills. Current Building Regulations dictate that homes should have 270mm (11 inches) of loft insulation cross-laid in the loft spaces. This amount of insulation can save you considerable amounts on your energy bills. Loft insulation acts as a blanket, trapping any heat rising from the house below.
Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with material that inhibits heat transfer. This immobilises the air within the cavity (air is still the actual insulator), preventing convection, and can substantially reduce space heating costs. Cavity Wall Insulation can save you up to 30% on your bills. Rockwarm arrange for the insulation of your property to be carried out by their teams of fully trained specialists, approved by certification of both the BBA (British Board of Agreement) and by KNAUF Approved Installers.
NBBC wanted to test the water and run a whole house transformation on 5 properties to see what was involved and help them plan a larger scale roll-out. We installed EWI, new windows, replaced porch roofs, and extended the main roofline. See the great results in this video. We are more than happy to answer any of your questions. Installing EWI and render is a big job that requires careful consideration before going ahead. That's why we are always pleased to advise customers as to the best options for their particular property.
External wall insulation is installed by adding a weatherproof insulating layer to the outside of your wall. This could be in the form of a protective render. The thickness of the insulation is usually between 60 and 100mm thick. The materials used for external wall insulation are often referred to as a "system" because there are three layers that must work together. The insulation material, the framework and the finishing layer. Render 1st, 2nd and 3rd coat. The second coat can look like the painted finish but it is a base layer.
