Description
STEICO Flex is a flexible, ecological insulation made from natural wood fibres.
STEICO Flex is a flexible and vapour-permeable wood fibre insulation that is equally suited to application in roof cavities, wall and ceiling structures and to cavity insulation in partition walls, facing formwork and installation levels.
A handy tip is to cut while it is within the packaging – this ensures the batts are held tightly and compressed, making cutting easier.
