Nastro autoespandente multifunzione EXP Multi

The multi-purpose self-expanding tape is an innovative compression product with an outer layer that is resistant to heavy rain and permeable to water vapour, a central section that acts as thermal and acoustic insulation, and an inner layer with vapour-barrier properties. The slow post-expansion that occurs after installation ensures that it remains compressed between the two elements, preventing the passage of wind, draughts, rain, noise and solar radiation, thereby ensuring perfect thermal insulation between the window frame and the building structure. It dampens any vibrations, accommodates expansion and protects against the ingress of atmospheric particulates. Suitable for installation on frames with a ‘Z’-shaped rebate made of metal, timber or PVC.

Instructions for use

Depending on the thickness of the window, choose tape of a suitable size. Discard the first few centimetres of each roll, peel back the paper from the self-adhesive side for approximately 20 cm, and stick the tape to the edge of the frame that has not yet been fitted, ensuring that it extends slightly beyond the edge. The light-coloured side of the tape, impregnated with polyacrylate, must face inwards as it is vapour-impermeable. Cut the tape flush with the edge of the frame and continue along the adjacent side, always ensuring the tape extends slightly at the start to guarantee that, once post-expansion has taken place, the joint is perfectly sealed and therefore watertight.

Storage

Multifunctional self-expanding tape in its original, unopened packaging, stored away from sources of heat in a dry place at a temperature between +5 and +35 °C.
