Klober Wallint T3 vapour barrier

Write the first review

Wallint® T3 is a three-layer vapour-tight membrane for use beneath prefabricated roof insulation systems. Its suitable SD value allows controlled water vapour transfer. This vapour barrier provides complete airtightness for the building element. An exceptionally tough bottom layer gives it high resistance to damage from rough substrates such as boarding or rafters. The protective nonwoven top layer adds safety when walking on the membrane during installation, even when the surface is wet. Wallint® T3 sits closely against the substrate and offers very high tear resistance, making installation exceptionally straightforward. Wallint® T3 also has high watertightness and UV resistance.

Material: polyolefin-based nonwoven/membrane

Colour:
  • yellow (top)
  • beige (bottom)

UV resistance EN1297-1: 4 months

Temperature resistance range: -40°C to +80°C

How we check reviews: we publish reviews confirmed by their authors via a link sent to their email address, no later than 24 hours after confirmation (during this time we may check them). Reviews containing links or contact details, and all photos, are checked before publication. The ‘Verified purchase’ label appears only on reviews whose author sent us proof of purchase of this product and where we confirmed the purchase at Ambit or at another wholesaler. Other reviews are not checked for a purchase. The average includes all published reviews, verified and unverified. We do not pay for reviews and we do not remove reviews because they are negative. We prepare translations of reviews ourselves and mark them; the original is always available. Details: Review terms.
