Internal wall insulation refers to the process of insulating the interior surface of an external wall in a building. This is done by adding a layer of insulation material to the inner surface of the wall, which helps to reduce heat loss from the building and improve its energy efficiency.

Internal wall insulation can be a cost-effective way to improve the energy efficiency of older buildings that may not have insulation in the walls, without the need for major structural alterations. It can also help to improve comfort levels in the building by reducing drafts and improving temperature stability.

The insulation material can be in the form of rigid panels, foam boards, and is typically fixed to the wall using an adhesive or mechanical fixings. Once installed, the insulation material is covered with a layer of plasterboard then plastered to create a smooth and even surface.

£200
Off Energy Bills

Installing internal wall insulation can save you up to £200 per year on heating bills by reducing heat loss through your walls, depending on your home’s size and energy usage.

25%
Heat Lost

Internal wall insulation can prevent up to 25% of heat from escaping through uninsulated solid walls, significantly improving your home's overall energy efficiency.

How does internal wall insulation work?

Internal wall insulation works by creating a thermal barrier on the inside of your walls. The insulating material slows down the transfer of heat between the inside and outside of your home, helping to keep warmth in during the winter and out during the summer.

Here are some commonly asked questions about Internal Wall Insulation, if you can’t find the answer to your question here please done hesitate to get in contact with us.

Internal wall insulation involves applying insulating material to the inside surface of exterior walls. This can include materials like foam boards, mineral wool, or plasterboard with insulation. The goal is to reduce heat loss, improve energy efficiency, and enhance indoor comfort.

Internal wall insulation works by creating a thermal barrier on the inside of your walls. The insulating material slows down the transfer of heat between the inside and outside of your home, helping to keep warmth in during the winter and out during the summer.

The main benefits include reduced heat loss, lower energy bills, improved comfort, and enhanced energy efficiency of your home. It can also help prevent issues like damp and mould by stabilising indoor temperatures and reducing condensation.

 

Yes, installing internal wall insulation will slightly reduce the size of your rooms, as the insulation material is applied to the interior walls. However, the reduction is minimal (around 4 – 4.5 inches) and is often outweighed by the benefits of improved energy efficiency and comfort.

 

The installation process for internal wall insulation typically takes 3 to 10 days, depending on the size of the property and the complexity of the installation. The process involves preparing the walls, applying the insulation, and finishing with plaster or other wall coverings.

While it is possible to install internal wall insulation yourself, it is usually recommended to hire a professional. Proper installation is crucial for achieving the best results and avoiding potential issues such as gaps, poor adhesion, or damage to existing structures.

 

There will be some disruption during the installation of internal wall insulation. This includes moving furniture, potential dust and noise, and minor changes to the appearance of your walls. We aim to work with you to minimise inconvenience and ensure a smooth process.

Yes, various government grants and schemes, such as the ECO4 scheme and The Great British Insulation Scheme, of which we are an approved installer, can provide fully funding for internal wall insulation. These programs aim to help improve energy efficiency in homes at no cost to the homeowner.
