Air-vapor sealing film FID

Air-vapor sealing film - internal

DESCRIPTION

Stretch and hydrophobic tear-resistant film to be applied to the connection joints on the wall to slow down the diffusion of air and steam. Equipped with a self-adhesive side, it is over-paintable and over-plasterable on both sides. & Nbsp; To be used only on the side towards the internal environment because it is impermeable to steam.

FIELDS OF APPLICATION

For sealing the counterframe on the side towards the internal environment. After filling the joint with foam this film is applied with the self-adhesive side to the counterframe and glued to the wall. In this way the joint will become permanently impregnable with air and steam and will offer excellent results in the case of a Blower Door test. It is the most economical alternative to the use of plasterboard profiles for interiors, but it requires more time for the application and above all, for a good adhesion, it needs a plastered shoulder.

Suggestions for use: clean the surface of the counterframe on which the film will be glued. Apply the tape with the self-adhesive part on the side of the subframe that will be walled starting from the bottom. On the corners form a loop that allows the film to turn towards the wall. Fill the space between the film and the wall with foam. Fold the sealing film over the foam and glue it to the wall using MS Powerflex 25 White creating a double bead of sealant or alternatively a ziz zag curb, so that the sealant adheres on a very large surface of the film. Do not use the Transparent color that is not suitable for this process.
