Ventilation chimneys offered by IZOBUD Sp. z o.o. are one of the most effective ventilating systems, leaching vapour which collects under the waterproof insulation. They increase watertight properties of protective layers and also extend their service life.

Ventilation chimneys help to avoid typical problems with membranes roofing of a poor ventilation, which are getting damp and loss of thermo-insulating properties of the thermal insulation layers.
