Kingspan Thermaroof TR24 insulation can improve the thermal envelope of your home. We recommend these boards for people who want the best thermal barrier for their flat roofs. They are comprised of a rigid PIR core with mineralised glass tissue on one side and bitumen coated glass tissue with a polypropylene fleece on the other. Each board has a thermal conductivity anywhere between 0.024 to 0.026 W/mK. We stock lots of thicknesses including 50mm and 130mm options. At Materials Market, there is a thickness for every kind of flat roof insulation project. TR24 Therma is not just known for its thermal properties. Kingspan manufacturers TR24 insulation with multi-layer bituminous waterproofing, and PIR is naturally water-resistant. You do not have to worry about the elements impacting the quality or longevity of these boards. They are ideal for people who live in areas with high rainfalls. Even better, they are non-deleterious, compatible with the majority of torch-applied waterproofing systems, and easy to handle.
