Many brands of floor insulation are available at build4less. Floor insulation is vital to help achieve a good insulation rating for your home. It is very important that you size the insulation correctly to maximize what you want to achieve from a u-value perspective. The thicker the insulation the greater the insulation thermal resistance, hence reducing a thermal bridge between two surfaces. Floor insulation ranges from 25mm to 150mm with all different thicknesses in between to suit every application. Cavitywall insulation would be used in conjunction with your floor insulation within your cavity and also attic insulation for your ceilings.
