Internal Solid Wall Insulation

What Is Solid Wall Insulation?

Types of internal solid wall insulation:

There are various ways to insulate a solid walled building from within, but they broadly fall into four categories:


- Rigid insulation boards

These come in a variety of materials and thicknesses and deliver the highest energy saving. Some have pre-attached plasterboard which makes the installation process more straightforward.


- Dry lining

Here, battens are fixed to the walls, insulation is fitted between them and then covered with plasterboard. This is a good option if the wall has a lot of heavy fittings such as book cases or kitchen cupboards, or if the original wall is rough and uneven, as in some stone properties.


- Insulated plaster

This is a mix of plaster and insulating material, such as cork. It is trowelled or sprayed on. It is a good option for uneven walls and can help achieve good levels of airtightness. 

How much does this cost?

Internally insulating your home will probably cost between £5,500 and £8,500, depending on the number of rooms are being renovated and the type of material being used. It's generally less expensive than external solid wall insulation because of the lower cost of materials and labour. A typical 3-bedroom semi-detached house using gas heating could save around £260 per year on heating bills by installing internal wall insulation whereas a detached house could save around £430 per year


Benefits of Internal Wall Solid Insulation

- Significantly reduce heat loss

One way you can significantly reduce heat loss within your home is to install insulation within its internal property walls. This is also known as dry lining. Firstly, insulating material is fitted to the inner surface of your walls. This is followed by a vapour barrier protecting the insulation against air penetration. This form of insulation is suitable for any property type and installation is very easy. By properly insulating your property, you can ensure the temperature in your home is consistent all year round. It therefore reduces the need to turn up the heating. 

- Reduce your bills dramatically

An astonishing amount of heat loss occurs through insufficiently insulated walls. In fact as much as 35%. Installing a thermal layer inside the home can significantly reduce your energy bills. It means you don’t need to use the central heating as heat stays in rather than escapes.


- You don’t need to change the property’s exterior

Unlike external wall insulation, internal wall insulation does not impact a property’s exterior. As a result, it’s appropriate for those wanting to boost their home’s energy efficiency, without changing its external appearance. The work can also be done room by room minimising any disruption.
