Solid Wall Insulation
Save money on your heating costs
If your home was built before the 1920s, its external walls are most probably solid walls rather than cavity walls.
Cavity walls are made of two layers with a small gap or ‘cavity’ between them, solid walls have no gap so they cannot be filled with cavity wall insulation.
The answer for solid walls to insulate them from either side of the wall, either on the inside or the outside.
Solid wall insulating does cost more than cavity wall insulation but will save you a lot more money.
Working out your wall type
If you cannot see the brickwork because it has been covered with cladding or render or something else, you can also tell by measuring the width of the wall. Examine a window or door on one of your external walls.
If you measure a brick wall and it is more than 260mm thick then it is most likely a cavity wall, if its any narrower then the wall is probably a solid wall. Stone walls may also be thicker still but are usually solid.
Internal wall insulation
Internal wall is generally cheaper to install than external wall insulation but will slightly reduce the floor area of any rooms in which it is applied (the thickness of the insulation is around 100mm). We always try to work with the minimum disruption but it will require skirting boards, door frames and external fittings to be removed and reattached.
Please note this work will not solve rising damp problems without the problem of that being dealt with first.
External wall insulation
The finish can be smooth, textured, painted, tiled, panelled, pebble-dashed, or finished with brick slips.
External insulation has lots of other benefits as well like:
It reduces condensation on internal walls and can help prevent damp but will not solve rising or penetrating damp.
