Areators are made of a special IGOM CE material of high resistance to UV rays, ozone and other atmospheric and chemical factors. Owing to the application of refining additions, chimneys maintain the elasticity and stability of measurements in a wide range of temperatures and they possess a momentary resistance to burner, which allows for welding them directly to papers.
The application of ventilation chimneys allows for releasing water steam gathering under hydro-insulation without reducing the capacity of hydrophobic bituminous coating and thermo-insulation of insulation layers. This allows for avoiding serious faults typical for waterproof roofings of poor ventilation, such as rolling, bulging, damping of thermal insulation and, as a result, a partial or total loss of its thermo-insulating properties.
Ventilation chimney (item i0049.1) is designed for ventilating thermo-insulation and a number of spaces (in connection with a ventilation pipe).

A) Ventilation chimney
B) Surface layer of weldable roofing paper
C) Prime coat of paper
D) Thermal insulation
E) Steam-tight insulation
F) Ceiling
