25mm Kingspan Kooltherm K5 External Wall Insulation Board is a premium performance external wall insulation board specifically designed for masonry walls. It features a rigid phenolic foam core, providing exceptional thermal insulation properties that help reduce energy consumption and enhance the overall energy efficiency of buildings. The board is faced with a low emissivity foil, further improving its thermal performance and making it suitable for both new build and refurbishment projects. Kooltherm K5 is particularly valued for its slim profile, allowing for effective insulation without compromising on internal space.

It is easy to handle and install, making it a popular choice among builders and contractors. The product is also resistant to moisture and has a high compressive strength, ensuring durability and longevity in various environmental conditions. This insulation board is suitable for use behind traditional and lightweight polymer modified renders, making it versatile for different aesthetic finishes. Additionally, Kooltherm K5 can be retrofitted externally to existing properties without disturbing the occupants, as all work is carried out from the outside.
