Kooltherm K108 is a premium performance partial-fill cavity wall insulation board made by Kingspan. The boards have an excellent thermal conductivity of ~0.019 W/k, allowing them to achieve the same U-values as comparable products, but with a thinner insulation thickness. The boards also have good compressive strength, and resist moisture penetration, helping to reduce damp issues. Common uses are for partial fill cavity wall insulation on both new builds and refurbishment projects, especially where you need to maximise available space. With a board size of 1200mm × 450mm, this pack of 5 panels has a coverage of 2.7 m².
