Airtight CEribel manufactures and installs a wide range of airtight windows, doors, and other interior joinery. The purpose of airtightness is to minimize air leakage as much as possible. Eribel offers products up to class C4, tested according to European standards in a recognized laboratory.
The air permeability of interior joinery is tested in a laboratory according to a European standard. Airtightness is expressed in 4 classes. The specified air permeability is measured at a pressure difference of 100 Pa. Do not confuse airtightness with smoke-tightness or flame-tightness.
Eribel doors can be airtight up to class C4, the highest class.
