ICB offers alwitra^® roof vents suitable for both warm and cold roofs. Manufactured to the highest standard, the venting provides superb air movement alongside reliable protection to rooftops.

The alwitra® Shaft (Soil) Vent Pipe forms the upper end of vent pipes protruding over low slope roofs. The soil vent pipe consisting of one single pipe extends over the roof build-up without any joints and is connected to the downpipe below the roof structure by means of the included reducer.

The alwitra® Cold Roof Vents facilitate air circulation in the cavity of ventilated roof structures, so called cold roofs. Only sufficient air exchange over the whole area will ensure long-term functionality of a cold roof.

A Polyurethane Vent is also available, made of rigid polyurethane with an Evalon® connecting strip.
