Insulation boards are a highly versatile form of insulation that offer excellent thermal efficiency thanks to innovative manufacturing processes and materials such as polystyrene. These boards are available in a wide variety of thicknesses from 25mm to 150mm, allowing you to achieve the desired level of insulation in the walls, floors and roof of your property.
The majority of our insulation boards are produced from polyisocyanurate, which is often abbreviated to PIR. Due to the thermal efficiency, safety benefits, convenient installation, and cost-effectiveness of PIR insulation, it can be found in millions of residential and commercial properties throughout the UK.
We offer insulation boards from a selection of leading brands. These include Celotex, Kingspan, Kay Metzeler and more. All of whom have been manufacturing PIR insulation boards for decades and become trusted brands amongst homeowners and tradespeople alike. This is largely due to their commitment to creating products that offer superb thermal insulation whilst not compromising on safety or ease of installation.

Different Styles of Insulation Boards
There are various styles of boards available to homeowners, each designed for specific applications and offering different benefits. Ensuring you use the appropriate insulation for your project is key to maximising thermal efficiency and simplifying installation.
Tongue and Groove Boards
One of the biggest challenges faced by insulation manufacturers is air leakage. This typically occurs at the edges of insulation boards, whether that be due to compression or poor installation. Tongue and groove boards are designed to combat this by ensuring there are no gaps where two boards join. They feature precision cut slots on the edges, allowing homeowners and tradespeople to easily slot the boards together.
Tapered Edge Boards
If you need to apply scrim or joint fillers to the edges of your insulation, you’ll benefit from tapered edge insulation boards. These are slightly thinner at the edges, allowing them to be dry-lined whilst maintaining a smooth and consistent surface. This feature is typically found on insulated plasterboards, which combines PIR insulation with plasterboard for fast and easy installation by both homeowners and tradespeople.
Squared Edge Boards
Many insulation boards don’t feature grooved or tapered edges as these are not necessarily the best solution for larger projects. Those that lack any form of slots are referred to as squared edge boards. Whilst they are vulnerable to air leakage if installed incorrectly, they are quicker and easier to fit in most circumstances. Making them perfectly suited for larger commercial projects as well as residential applications where you want to minimise disruption.
Leading Manufacturers of PIR Insulation
We’ve partnered with trusted manufacturers from across Europe to offer a solution for everybody. These include the likes of Kingspan, which has been producing insulation boards since 1965 and is trusted by homeowners in over 70 countries worldwide.
Celotex Insulation Boards
Since the 1970’s Celotex has invested heavily in the development of innovative insulating materials. This can be seen throughout their range of products, such as the Celotex XR4000 and Celotex GA4000 PIR insulation, which each offer the highest level of performance whilst not compromising the safety of a home or office.
Kingspan Insulation Boards
Kingspan has become a global leader in high-performance insulation since its formation in 1965. Throughout this time, they have also become increasingly conscious of the environmental impact PIR insulation can have. This led to the adoption of industry-leading sustainability practices, which has helped save the equivalent of 110 million barrels of oil between 1993 and 2018.
Established in Essex during the 1960s, it has become a trusted manufacturer of insulation throughout the past 50 years. Their products, which include the Kay-Cel range, are renowned for their cost-effectiveness whilst still providing superb thermal insulation throughout both residential and commercial properties.

Frequently Asked Questions
What is PIR Insulation?
Polyisocyanurate or PIR insulation is a popular form of insulation due to its versatility and superb thermal efficiency. It’s one of the most common kinds of insulation in use today, particularly in new build properties throughout the UK.
PIR insulation boards are manufactured by combining several materials together to create a rigid foam board that’s often placed between two foil facings. This protects the insulation board from moisture, one of the most common causes of damage and biggest reasons for inefficiency.
PIR boards is used in a variety of applications, such as loft, wall and floors. It is also incredibly simple to install thanks to its rigidity, which also prevents them from sagging and becoming less effective.
The polyisocyanurate formula used in PIR insulation boards also provides up to eighty times more thermal insulation than alternatives. When combined with the foil facing used by brands such as Celotex, this allows you to prevent thermal-bridging and offers protection from moisture.
Are These Insulation Boards Waterproof?
While PIR insulation boards are generally resistant to moisture, they are not fully waterproof. You should therefore avoid leaving them exposed to rainfall or using them in locations where they will be exposed to water.
Insulation boards exposed to excess water become far less effective, as the moisture fills the air pockets in the insulation board and prevents air from being trapped in there. Excess moisture will also encourage mould build-up on your insulation boards, which will then need to be replaced.
Is PIR Insulation Flammable?
Whilst we urge you to refer to the manufacturer’s fire testing certifications, commercially available PIR insulation is not typically flammable. Much like other types of insulation, such as mineral wool, it has been specially designed to be non-combustible.
What’s more, when placed under extreme heat these insulation boards produce little smoke and will not melt or drip. This ensures the safety of your family and protection of your property in the unfortunate scenario of a fire occurring.
How to Cut Insulation Boards
Rigid insulation boards are very simple to cut cleanly, even for homeowners. All you need is a sharpened utility blade or craft knife.
- Mark out where you want to cut using a straight edge and a marker pen.
- Carefully slice along the marked edge.
- Repeat the cut once more to ensure a full, clean separation.
And you’re done! As always, consult the manufacturer’s guidelines and wear appropriate safety equipment before commencing any work.
