Certainfil Cavity Insulation Limited is a second generation family business specialising in installation of Bonded Bead Cavity Wall and Fibreglass quilting loft insulation. As KIWA certified installers our cavity wall installations come with a 25 year GDGC guarantee and our loft installations are completed to Building Control requirements. You can save up to 40% on your fuel bills and it benefits the environment as well as your pocket. By insulting the cavity space between your internal wall and external brickwork you will reduce the amount of heat lost through the walls and therefore help to retain the heat in your home for longer.
Certainfil Cavity Insulation Limited uses a high grade silver graphite expanded polystyrene bonded bead (EPS) system of installation. Silver graphite bead is typically 20% more effective at reducing heat loss than the older "white" bead that may also be offered by other installers. Beads arrive at your home already manufactured to the density required by the Agrment Board and they are simply blown into the wall from the truck and sprayed with an adhesive so that they form a bonded mass. Because installation of cavity wall insulation is done externally there is no need for anyone to be at home during the installation which is usually completed in one day.
