Certainfil Cavity Insulation in Northern Ireland


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 Qualitymark Protection guarantee and our loft installations are completed to Building Control requirements.

An un-insulated home can lose 35% of its heat through walls and 25% through the loft.

You can save up to 40% on your fuel bills and it benefits the environment as well as your pocket.

Properly insulating your home can dramatically reduce heating bills and increase warmth. The risk of black mould growth developing within the house is also reduced.

How the heat is lost without insulation

Home Warming

Home Warming not Global Warming

By insulating 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.
