Ventilation for uninsulated Roofs

When planning or designing ventilated roof constructions (uninsulated roofs), ventilation is an important detail. In any case, the requirements of the Flat Roof Guidelines should be taken into account regarding planning of ventilation for ventilated roof constructions. For further information, please see DIN 4108 – Thermal Protection in Building.

Kaldomat, the ventilation system for uninsulated roofs made by POHL has a cross-section of 200 cm², the biggest available in the market, which means that you need approx. 50 % less ventilation tubes than usual. At the same time, you have 50 % less holes in the roof area.

The material is not PVC, i.e. it is economical/environment-friendly and made of shock-resistant plastic PP. In addition, Kaldomat has an all-around perforation for nail-fixing of bitumen.
