ME500 foil is used to seal window joints. The variable value of the S _d coefficient allows both indoor and outdoor use. The product consists of a polyethylene copolymer coating and nonwovens. The foil complies with the RAL recommendations and the principle "tighter inside than outside". A fully installed film should not be exposed to the sun and UV rays for more than 3 months; ME501 Duo HI is recommended for longer exposure - 12 months UV resistance.

properties

Duo EW

• flat foil
• for one-sided or alternate sticking
• one foil from the inner and outer layer of sealing
• the foil used in the window joint reacts with the surrounding moisture 365 days a year
• the adhesive element can be used on both sides

Duo EW +

• for one-sided or alternate sticking
• special adhesive strip for the frame or wall
• can be glued on a damp surface (in combination with ME904 primer)
• extremely high adhesion on various construction surfaces

We also offer Duo foil in a functional dispensing carton. The handy packaging dispenses the right length of the film, does not twist during unrolling, and moreover, in this version there is a longer aisle than in the basic version, so there is no need to change the rollers often. A practical solution that allows packaging to be moved around the building site with one hand.
