Selection of the Nordic cold areas of quality pine, indegreasing capsule Chuba dry section of termites and otheranti-corrosion treatment after a reasonable means to deal withpressure and to ensure that the wood window frames and Chuangshanhave excellent stability and the beginning of strength.

A double-hollow float glass production process (4 mm 9 mm 4 mm)with a good finish surface roughness, insulation, thermalinsulation, acoustic characteristics.

Sealing materials from the inside to the outside were selectedweathering butyl rubber and silicone sealant.

Use of hollow aluminum at the German Ringelmann, a desiccantcontents - bubble zeolite, can absorb large number of water vapor.In order to better serve the noise, insulation and other role isnot to condensation.
