Applied Fleeces

Roof sheeting is now available with a synthetic fleece applied directly to the underside of the profile. This works in the same manner as roofing underlay, absorbing condensation into the fleece and releasing it into the atmosphere when ambient conditions improve.

The fleece follows the contours of the profile. By removing the separate layer of underlay, every crest becomes a pathway for ventilation. On a gable roof, this will approximately double the air changes in a roof over conventional construction, without the height disruption, cost, or inconvenience of a ventilated batten.

Another advantage of these products is that they greatly increase speed of lay of a roof, and avoid delays due to excessive wind. They are available on all corrugate and trapezoidal profiles.
