InsulationThermataper TT46
Thermataper TT46 is a high performance tapered insulation system, providing insulation and drainage in one. It is designed to enhance water drainage for flat roofs waterproofed with mechanically fixed single-ply waterproofing. Thermataper TT46 comes with a supporting design service. This ensures that the most cost-effective solution for a flat roof is identified and that the end result is a tapered system design that meets the roof’s rainwater run-off and insulation requirements. -
InsulationOPTIM-R E Inverted Roofing System
The OPTIM-R E Inverted Roofing System is perfect for projects that require the lowest U-value or the thinnest roof build-up. It is ideal for where there is little space for installing new roof insulation. OPTIM-R E is encapsulated in a coating for increased robustness and easier handling on-site. The vacuum insulation panels are accompanied by rigid extruded polystyrene insulation infill panels which can be cut to fit around problem areas such as roof lights or ventilator kerbs. -
InsulationEco-Cavity Full Fill
Eco-Cavity Full Fill is a cavity wall insulation board with a thermal conductivity of 0.022 W/mK. Eco-Cavity Full Fill is ideal for use with masonry walls and is suitable where the requirement is for insulation to completely fill the cavity, whilst maintaining a residual 10 mm cavity to resist moisture transfer. -
InsulationKooltherm K107 Pitched Roof Board
Kooltherm K107 is a premium performance pitched roof insulation board. Suitable for use in tiled or slated pitched roofs, dwarf walls, attic floors, dormer windows and flat ceilings. The insulation boards can be simply retrofitted when converting an attic where re-roofing is not needed. The boards are easy to cut and handle, ensuring an efficient installation process. They can easily be trimmed to size to suit rafter spacings. Product Highlights One of the thinnest commonly used insulation for pitched roofs, allowing U-values to be reached with minimal thickness. Isn't susceptible to sagging over time. Perfect for creating a usable attic / loft space or attic / loft renovation project. Less likely to need additional insulated plasterboard due to excellent thermal performance. Low emissivity foil facing reduces heat loss through the roof and could help save on energy costs. BIM objects available using the Kingspan BIM Designer Software Tool. Lightweight insulation that is easy to transport, handle and install. Part of our Kooltherm range of premium performance insulation. Our Toolbox Talks are delivered by dedicated technical experts, who provide free onsite training and guidance. -
