Dimensional drawing
Vapour-barrier polyethylene sheet, 0.92 g/cm3 of density, 200 μm of thickness,
supplied in centre folded rolls of 3 m in overall width and 66 m in length.
According to UNI 11371, it is necessary to lay a vapor barrier under the insulating
panels of a screeds with radiant systems and wooden surface coatings.
Use
The polyethylene sheet has the function of separating the various layers of material:
•
In residential systems, if properly placed overlapping the edges and sealing
them with adhesive tape, it is a barrier to vapour or rising humidity. According to
UNI 11371, it is necessary to lay a vapor barrier under the insulating panels of a
screeds with radiant systems and wooden surface coatings.
•
In industrial systems, if properly placed on the lean concrete overlapping the
edges and sealing them with adhesive tape, it is a barrier to rising humidity,
although it is always a good idea to evaluate the use of bituminous membrane
