If your property has floor boards then in most cases drafts are more apparent, the cold air rises up through the floor boards and carpets, in some cases you can see the carpet rise as the cold air penetrates up into your home. This is like your loft where heat rises then without loft insulation it’s lost through the roof, same as your floor your heat in your room is lost due to the cold air rising into your home. Underfloor insulation is designed to minimise cold air rising ensuring that your home retains the heat and keeps your home warmer and more efficient.
