Belgafoil SA-L in - internal self-adhesive window tape

Belgafoil SA-L in is a high performance window tape from Belgaclima (Belgium), which was developed for the internal sealing of the joints around the window frame. It is air tight, vapour inhibiting and fully self-adhesive. 


The tape consists of a reinforced and air tight PP foil/ fleece combination. On the backside it has a high tack adhesive layer (IGT - Intelligent Glue Technology) on the full surface that allows a simple and completely hidden installation of the window tape without additional glue/ sealant to (almost every) smooth substrate. The topside has a very good grip to ensure a subsequent plaster coating.


The tape is available in different widths, from 75mm  up to 300mm (on request). 

Every roll has a length of 25m. For easy application, the tape comes with split-release liner (2 or 3 liners)  and finger lift.


Belgafoil SA-L in is the perfect window tape for all types of building structures, like cavity wall, block-on-flat or timber frame.
