Floor Insulation Johannesburg

Professional Floor Insulation Contractors in Johannesburg


Floor insulation is a firm, polystyrene or fibreglass based material that is installed underneath your floors to prevent heat from escaping and create a barrier for any air movement. Floor insulation is normally only installed in new developments or if floors are being removed for other structural purposes. In order to install floor insulation, the entire surface area needs to be chopped up which is why we rarely find clients wanting to install floor insulation in an already developed home.

Most of the energy transfers in a home occur through the roof although the floor plays a vital roll as heat is lost through all directions. If you have solid wooden floors, fibreglass insulation is an ideal solution for providing thermal and acoustic performance. A floor that is not insulated will lose up to 20 per cent of internal heating or cooling.
