25mm Kingspan Thermaroof TR26 Flat Roof Insulation Board 2400mm x 1200mm

25mm Kingspan TR26 is a high-performance insulation board. It is designed to reduce the amount of heat that homeowners lose through their flat roofs. Each board is comprised of a rigid thermoset PIR core that has two composite foil facings on either side. Overall, the board has a thermal conductivity of 0.022 W/mK. 

PIR is often a popular choice for homeowners who want to reduce their energy bills because it delivers excellent thermal protection at an affordable price. Kingspan Thermaroof TR26 boards are very versatile. 

They are manufactured to high standards and are suitable for both new build and refurbishment projects. They are fully compatible with flat roofs that have mechanically fixed single ply waterproofing systems, most green roof systems, and metal deck roof assemblies. 

Although you should always install Therma TR26 insulation with an additional waterproof membrane, the board itself is resistant to water vapour. When you choose TR26 for your flat roof insulation project, fungi and rot are a thing of the past.

Kingspan Therma TR26 is comprised of a rigid thermoset insulation core of polyisocyanurate (PIR) that is sandwiched between two low-emissivity composite foil facings. By insulating flat roofs, you can improve the overall thermal envelope of your home. PIR insulation has a thermal conductivity of 0.022 W/mK, which makes it one of the best thermal insulators on the market.

Kingspan manufactures Thermaroof TR26 with the environment in mind. These boards are manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). TR26 is perfect for people who want high-performance materials that have a low environmental impact.

Kingspan Thermaroof TR26 50mm is has a pack coverage of 17.28m2.

Kingspan TR26 Insulation Applications

Kingspan specialises in creating tailor-made insulation boards for specific purposes. Kingspan TR26 25mm insulation is designed for installation in flat roofs. Whether you have a flat or pitched roof, you need to insulate your space. Homeowners lose around a quarter of the heat in their homes through their roofs, which makes them a focal point for people who want to reduce bills.

Kingspan TR26 is compatible with most flat roofs waterproofed with mechanically fixed single-ply and most green roof systems. Any flat room system would benefit from the thermal qualities of TR26. This board is even suitable for new build, refurbishment, or fast track building projects. 

Kingspan Thermaroof PIR Core

PIR (polyisocyanurate) is the go-to choice for people who want affordable insulation that delivers excellent thermal protection. Kingspan Therma TR26 has a fibre-free rigid thermoset PIR core.

There are lots of benefits of choosing PIR, with one of the biggest being thermal performance. PIR has a thermal conductivity of 0.022 W/mK. Thermal conductivity is the most important consideration for people who want to reduce their energy bills and keep their homes warmer for longer. PIR is second only to phenolic insulation in items of thermal performance.

Kingspan TR26 also benefits from the other qualities of PIR. It is water-resistant and non-deleterious. You can handle and install these boards without worrying about health concerns.

Kingspan TR26 Insulation Fire Rating

All insulation materials have a fire rating. The Euroclass scale awards insulation materials across Europe with a rank from A1 (non-combustible) to F (combustible). Materials undergo up to five different tests to achieve a fire rating.

Thermaroof TR26 has a Euroclass rating of E, meaning it has a high contribution to fire. A poor Euroclass rating does not mean that you should avoid the material. Lots of insulation materials are very thermally efficient, but also contribute to the production of fire. You can use a build-up of materials that do not contribute to fire to safeguard your home.

Kingspan Thermaroof TR26 Water Resistance

One of the added benefits of Kingspan TR26 boards is that they are water-resistant. The rigid PIR insulation core is resistant to water. The core is sandwiched between two composite aluminium foil facings, which are also resistant to water. Despite all this, you should always install Kingspan TR26 insulation with an additional waterproofing system.

Lots of homeowners choose water-resistant insulation. When you choose insulation that is resistant to moisture, you do not have to think about fungi or rot. Rot can impact the longevity of your insulation materials.
