DIY Building Supplies is the top destination for PIR insulation products. We carry a wide selection of PIR insulation from the leading brands such as Celotex and Recticel (available in many lengths, widths, and thicknesses), making it easy to find the right product for your needs. PIR is a great option for insulation as it is known for its strong thermal performance, helping to improve energy efficiency in a building - a key consideration for builders and homeowners alike. Keep reading for all you need to know about PIR insulation.
What is PIR Insulation?
So, what exactly is PIR insulation? PIR boards are rigid boards that create an insulation envelope around a structure, helping to improve thermal conductivity. They are a popular choice due to their extremely low thermal conductivity and the fact that they are lightweight, easy to install, and moisture-resistant. PIR insulation is known for its low thermal conductivity, durability, and long-lasting nature, making it the go-to choice for many builders.
What is PIR Made From?
PIR is shorthand for Polyisocyanurate - a thermoset polymeric material made by blowing agents (such as foam insulation) formed into solid boards. PIR is similar to polyurethane, which is a popular insulation material that has been used extensively in construction since the 60s. Technical developments over the years led to the creation of PIR, which improved the material's thermal stability and fire resistance, making it the superior product and go-to option for builders nowadays.
What is it PIR Used For?
PIR is an excellent insulation material because it can be used in many different applications thanks to its thermal resistance. The most common uses of PIR boards include:
Wall insulation
You can use PIR boards for insulation on external and internal walls to improve the thermal efficiency of the building. Most commonly they are used as Cavity Wall Insulation, but they can also be used in partition walls.
Floor insulation
PIR boards can also be used to insulate both solid and suspended floors. Energy loss through the floors is a common issue, but PIR can reduce this, helping to maintain a comfortable temperature while reducing reliance on heating systems.
Roof insulation
PIR insulation boards are perfect for insulation on pitched and flat roof applications for thermal efficiency.
Where to Use PIR Insulation?
The fact that PIR insulation boards can be used throughout both residential and commercial properties indicates just how versatile they are. They can be used in many different projects, and are very popular for insulation in new build projects, allowing builders to meet energy-efficiency building regulations. PIR insulation is also easy to install and can be used for retrofit projects, helping existing property owners improve the thermal efficiency of the building. This is something that many are looking to do as the cost of energy is a concern for many in older homes who lack modern energy-efficient features. PIR is also commonly used in warehouses and factories where it is important to maintain a consistent internal temperature at all times.
What Happens if PIR Insulation Gets Wet?
Although PIR insulation has greater moisture resistance than other insulation materials, thanks to its advanced closed-cell structure, you must try to avoid moisture exposure as it is not water-resistant. The thermal performance of the board could be compromised if exposed to moisture, so it is important to keep this in mind when handling, storing, and installing PIR boards. If PIR insulation becomes wet before installation, it should always be dried out thoroughly before being used.
How Long Does it Last?
PIR insulation is the go-to choice for many builders these days for many reasons, including its long-lasting nature. When protected from damage and moisture, PIR boards will last for several decades and potentially as long as the building itself. This also means it is cost-effective, as you do not have to worry about replacing it.
What are the Benefits of PIR Insulation?
There are a number of reasons why you should choose PIR insulation over PUR and other insulation materials. The main benefits of PIR insulation include:
High thermal efficiency: PIR insulation has one of the lowest thermal conductivities, providing excellent thermal efficiency. This can help property owners maintain a comfortable temperature while reducing reliance on heating systems, helping to minimise environmental impact and save money.
Lightweight: Due to the fact that PIR boards are lightweight, they are incredibly easy to handle, transport, and install.
Versatile: As established, PIR boards are highly versatile and can insulate walls, floors, and roofs in new construction and retrofit projects, and are easily cut to size.
Moisture & Fire Resistant: PIR is moisture resistant compared to alternative solutions, helping reduce the risk of dampness and mould growth. It is also a thermoset material, meaning it will not melt when exposed to high temperatures - this helps add a layer of fire protection (a key issue for every property owner).
Sustainable: Sustainability is an important consideration when it comes to insulation. Many PIR manufacturers use eco-friendly blowing agents, and boards can be recycled, making them a popular option for eco-conscious construction companies and homeowners.
What Products Do We Sell?
Here at DIY Building Supplies, we carry a huge selection of PIR insulation products from the top brands. We carry boards in a range of thicknesses and dimensions, making it easy for you to choose the best fit for your insulation project. You can also cut PIR insulation to size with a sharp utility knife or handsaw if you have purchased a thicker board. PIR is designed to be friction-fit, which means the board should fit snugly without the need to use additional fixtures and fittings. We carry PIR insulation boards and plasterboard insulated with PIR insulation from the top brands, including:
