Prepare your home for winter and reduce your heating bill with our Knauf loft insulation. Up to 25% of heat is lost through the roof so work to prevent that with our range of 100mm, 150mm and 200mm loft rolls. We are also proud to keep Knauf's Omni-Fit roll, which adds excellent acoustic performance as well as superior thermal performance to standard loft insulation. Planning to convert your attic? Consider using Knauf Frametherm between the rafters to keep the heat in, and the cold out.
