Internal Wall Insulation

About 35% of all heat loss from UK homes is due to un-insulated external walls.

 

Internal wall insulation is perfect for solid wall homes where you can't alter the outside of the property.

​

If your home was built before 1920 there is a strong likelihood that your property has solid walls.

​

You can check your wall type by looking at your brick pattern.​ If some of the bricks are laid with the square end facing, the wall is likely to be solid. If the wall is stone, it is likely to be solid.

​

Internal wall insulation is installed on a room by room basis and is applied to all exterior walls.

 

Polyisocyanurate Insulated (PIR) plaster boards are usually used creating a dry-lined, insulated internal wall. The internal walls are then plastered to leave a smooth and clean surface for redecoration.

Bill savings and things to be aware of:

​

• Can save between £195-£650 a year on your fuel bills depending on property size (Figures from the Energy Saving Trust and assume property is a gas heated home and sized between a small flat to a large detached home).

• Not only will this make your house warmer in winter but it will also save you money by slowing the loss of heat through un-insulated walls.​

• It will slightly reduce the floor area of any rooms which it is applied (roughly about 100mm per wall)

• Can be quite disruptive to install and does require the removal and re-fixing of items such as switches and radiators.

• Any issues with penetrating or rising damp must be rectified before install can commence.

• Grant funding is available that can cover the full cost of installation (qualifying criteria apply).
