AEROCONNECT SD20 is an airtight plaster joint membrane with a fully adhesive underside and an adhesive strip on its surface, for interior use. It is composed of an airtight film combining PP with a strengthening fibre sheet. The entire lower face of the membrane is coated with a very strongly adhesive layer, meaning it can be fitted easily and completely invisibly. It can be plastered over without needing to use additional glue on the (smooth) masonry substrate. Developed to provide the joint between woodwork and plaster, it can be applied to the interior of the window. The gluing surface must be sufficiently flat.
