Insulation for walls can be used to improve the thermal performance of a building. The purpose of wall insulation is to reduce heat transfer, making the interior spaces more energy-efficient and comfortable.
There are various types of wall insulation materials available on our website. This includes PIR boards and fiberglass. These materials work by trapping air pockets, which act as insulating layers and prevent heat from escaping or entering the building.
Insulation for walls is an essential component of energy-efficient construction and renovations, helping to maintain stable temperatures and improve the overall energy performance of buildings.
Rigid foam boards, also known as PIR insulation, are manufactured from polyisocyanurate. These boards provide high thermal resistance and are often can be used for multiple purposes. For example, the Celotex PIR range can be used in walls as well as floors and roofs.
Other common wall insulation materials include fiberglass or mineral wool. Fiberglass is a lightweight and cost-effective option, which consists of fine glass fibers. These fibers create an effective thermal barrier. It is easy to install and can fit snugly between wall studs or in wall cavities. Mineral wool is slightly different as it is made from natural or synthetic fibers, which are derived from minerals. Rockwool is a known manufacturer of mineral wool insulation. Both fiberglass and mineral wall offer great fire resistance and sound absorption properties, making them ideal for both thermal and acoustic insulation. Additionally, it is said that mineral wool is resistant to mould and pests, ensuring a healthier indoor environment.
Insulated walls can contribute to a quieter and more peaceful indoor environment by blocking external noise pollution in addition to having thermal qualities.

Wall Insulation Boards
We stock a wide variety of wall insulation boards on our website. This includes top brands such as Celotex, Kingspan and Recticel. Our Celotex general purpose boards are a very popular product when it comes to wall insulation boards.
On our website, you can find wall insulation boards for many types of wall applications. This includes cavity walls as well as solid walls.
Wall insulation boards are a crucial component in creating energy-efficient and comfortable living spaces, offering both warmth in the winter and coolness in the summer. Among the various types of insulation materials available, PIR (Polyisocyanurate) insulation boards stand out for their exceptional thermal performance, durability, and versatility. Celotex, a leading brand in the insulation industry, is renowned for its high-quality PIR insulation boards, making it a popular choice among homeowners, builders, and architects.
PIR wall insulation boards are made from polyisocyanurate, a type of plastic closely related to polyurethane but with enhanced thermal performance and fire resistance. These boards are recognised for their excellent insulation properties, which stem from their fine, closed-cell structure that traps air and reduces heat transfer. PIR boards are lightweight, easy to cut and install, making them well suited to wall applications.
On our website, we offer our very best price on wall insulation boards.
How to Insulate a Wall with PIR Boards
Insulating walls with PIR insulation boards is a good decision that can lead to substantial energy savings and a more comfortable indoor environment. An architect or building professional should be able to offer advice on which product/s you need. A professional can help you determine the thickness required for your boards.
Once you have purchased your wall insulation from us, you will need to gather additional equipment and PPE. This includes gloves, goggles, wall ties, measuring tape, a utility knife and mechanical fasteners.
The type of install will depend on the application so we recommend reading the manufacturers guide. Installing PIR cavity wall insulation, you would do the following:
- Position wall ties one course below the damp proof course, 600mm apart horizontally.
- Install subsequent rows of ties at 450mm intervals vertically and 900mm horizontally if possible.
- Secure the insulation boards between the ties using retaining clips.
- Ensure full and cut boards are held by at least three ties around their perimeters.
- Use insulated cavity closers for windows, doors, or openings.
- For cavities below the DPC level, use mechanical fixings to secure the boards.
If you were to upgrade solid walls with insulated plasterboard, then you could use the dot and dab method below:
- Apply adhesive at skirting, ceiling level, and openings for a continuous seal. Alternatively, use thin timber battens at perimeter edges.
- Align the insulation against adhesive and secure it in place. Add more adhesive if needed, following the manufacturer's instructions.
- After the adhesive sets, apply secondary fixings to the insulated plasterboard as per manufacturer recommendations.
- Ensure tight alignment of board joints and use appropriate tape and joint material to create a vapor control layer.
Wall Insulation Slabs
Insulation slabs are often used in cavities to improve both thermal and acoustic performance. Cavity wall insulation slabs are designed to fill the air gaps or cavities between the inner and outer walls of a building. These slabs are usually made of materials like mineral wool or fiberglass. They create a thermal barrier to improve performance. These insulation slabs can be easily slotted into the relevant cavity space.

The benefits of insulating walls
Insulating walls offers numerous benefits, which we have outlined below:
- Insulating walls creates a thermal barrier that can improve thermal performance of the building.
- Wall insulation can help people to save money on their energy expenses. Over time, the cost savings can offset the initial investment in insulation.
- Properly insulated walls contribute to a more comfortable indoor environment. Insulation minimises drafts, cold spots, and temperature fluctuations, creating a consistent and pleasant living space.
- Using insulation with acoustic properties can help reduce noise pollution and reduce sound travelling through walls.
- Insulation reduces the need for excessive energy consumption to heat a home. This means fewer greenhouse gas emissions therefore helps to build a more sustainable future.
- Wall insulation can reduce condensation and moisture build up causing damage to the building.
- Well insulated buildings tend to fetch a higher price on the property market.
- Building regulations in England mandate the use of insulation in new constructions or renovations. The use of wall insulation can help with compliance.
- Better temperature control can reduce the risk of temperature related health issues.
Please note that wall insulation properties will differ depending on the product. Ensure that you read the relevant data sheets.
