Aluminum Wood window

Features:
European aluminum coated wood doors & windows adopt solid laminated wood as main body material and external aluminum alloy section coating, not only guaranteeing the elegant and classic internal decorations, but also overcoming the poor weather resistance. In addition, the solid wood main body has more excellent heat insulation and noise isolation properties than the aluminum alloy doors & windows and the wood-aluminum doors & windows.
Considering the weather difference in south and north, the company develops 73 series (window thickness 73mm) adaptive
to south areas and 85 series (window thickness 85mm) adaptive to north areas.
To guarantee the quality, European aluminum coated wood doors & windows adopt excellent raw and supplementary materials, Germany paints and main sealing tapes as well as fittings produced by powerful domestic partners to provide the excellent products.
