Vented sheets are incorporated into building design to promote natural circulation of air. Used particularly for agricultural applications, this sheet facilitates healthy conditions for livestock in poorly ventilated areas.

Sheeting is rolled in reverse profile and vents formed at 25mm centres with each vent being 50mm wide.

(see diagrams below)

An alternative method of promoting ventilation is with the use of vented ridges. These essentially are flashings into which ventilation holes have been punched.

These are manufactured within our flashing department to client specifications.
