Internal Wall Insulation - Smart Energy Homes
Internal wall insulation

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, or flexible rolls, 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. 

If your house was built before 1930 then you probably have a solid wall or stone wall property, these can be colder and more expensive to heat than cavity wall properties as they don’t retain heat as well. Internal wall insulation helps retain the heat for longer and can help reduce energy bills.

A typical Internal wall Insulation Installation could take between 1-3 weeks

Ventilation Included

Clean air is essential for healthy living and for preventing damp and mould. With every install of insulation we assess ventilation and install any needed upgrades.

Lower Your Emissions

Insulation reduces heat loss which removes the reliance on gas or electric heating, reducing your carbon footprint.

Save Money

Ensuring your property is correctly insulated can save you loads of money each year on your energy bills.

Fully Qualified

All of our installers are fully qualified and accredited ensuring you get the best install available.

According to a survey taken by the Energy Saving Trust an average detached house could look to save an outstanding £930 per year on their energy bills by installing solid wall insulation.

Why insulate solid walls?

Solid walls don’t retain heat as well as cavity walls, if you have a solid wall you could lose a massive 45% of your properties heat through your walls alone. Internal wall insulation can make your warmer for longer and save you money on your energy bills each year.

How is Internal Wall Insulation installed?

Internal wall insulation is installed by fitting rigid insulation boards to all outer facing walls. It is install by first extending any electrics in the room and building a stud wall, then filling it with insulation material and finally finishing with plasterboard.

Having Internal wall insulation can be a lengthy and process depending on the size of the property and usually takes between 2 to 3 weeks to install. To make this process less disruptive our installers work room by room and can work to your preference.

Frequently Asked Questions (FAQ's)

What is internal wall insulation?

Internal wall insulation is a method of insulating the interior surface of external walls in a building to improve thermal efficiency and reduce heat loss.

What are the benefits of internal wall insulation?

Internal wall insulation can enhance thermal comfort, reduce energy consumption, lower heating bills, and improve the overall energy efficiency of a building.

What materials are commonly used for internal wall insulation?

Common materials used for internal wall insulation include rigid foam boards, mineral wool, and insulated plasterboard.

Is internal wall insulation suitable for all types of buildings?

Internal wall insulation can be applied to most types of buildings, including both solid and cavity wall constructions. 

How is internal wall insulation installed?

Internal wall insulation is typically installed by fixing insulation boards or panels to the interior walls using adhesive, mechanical fixings, or a combination of both. The insulation is then covered with plasterboard or other finishes.

Will internal wall insulation reduce room sizes?

Internal wall insulation will slightly reduce the floor area of rooms as the insulation boards or panels add thickness to the walls. However, the impact on room sizes is generally minimal and can be managed through careful planning and design.

Does internal wall insulation cause any issues with dampness or condensation?

Proper installation and moisture management are crucial to prevent dampness or condensation issues. It’s important to address any existing moisture problems, ensure proper ventilation, and use insulation materials with appropriate moisture resistance properties.

Under ECO4 ventilation is assessed and installed as part of every measure installed.

Can internal wall insulation improve sound insulation?

Yes, internal wall insulation can help improve sound insulation by reducing sound transmission between rooms and from the outside. Insulation materials with good acoustic properties, such as mineral wool, can be used to enhance soundproofing.

Will internal wall insulation require changes to electrical wiring or plumbing?

In some cases, internal wall insulation may require adjustments and exertions to electrical wiring or plumbing. Our Retrofit Assessors will explain any changes and be open to any questions you might have.

How long does internal wall insulation last?

Internal wall insulation, when installed correctly and maintained properly, can last for several decades.
