Alkreflex® 2.5 is a multi-layered insulating membrane, which is ideal for use on walls and roofs. Alkreflex® 2.5 features a core of high-density wool, enclosed within two reflective vapour barrier membranes. Alkreflex® 2.5 combines heat reflection (infra-red) with core insulation to improve the construction’s overall heat resistance. The multi-layered insulation membrane does not feature stitches, which means air and moisture leaks can be avoided.
