Hello all, new to all this as I have just moved into a new (for me) house. I am considering getting cavity wall insulation installed but have found out that the inside of the external walls of my 1992 built house are made from insulated plasterboard similar to this stuff
So given that the walls are already insulated will filling the cavity make much difference?
Thanks Tracy
Additional insulation in the cavity will reduce heat loss. A firm local to you will probably be able to advise you on the phone regarding suitability, otherwise they can do a free survey which they have to do anyway to check that the property is suitable and to work out the cost less grants.
If the cavity is uninsulated, filling it will make a difference, but the savings will not be as much as on an uninsulated wall. Is the cavity not already insulation filled?
