Kingspan K7 roof insulation panels provide performance rigid thermoset insulation. They are available in a variety of dimensions. The thermal boards are unaffected by air infiltration and resistant to water vapour leading to long lasting durability. Thermapitch insulation boards are easy to handle and safe to install and are ideal for both new build and refurbishment. They are made from a deleterious material that is manufactured with a blowing agent that has zero ODP and low GWP. For any help or tips using this or any of our products please contact us today.
