First of all, it should be divided into indoor or outdoor use.
Indoor can be aluminum alloy or broken bridge aluminum, aluminum clad wood, etc.
Outdoor broken bridge aluminum or plastic steel is better.
Their differences are as follows:
Aluminum-clad wood: easy to process and repair, more light blocking, good thermal insulation performance, and easy deformation of solid wood materials during use.
Broken Bridge aluminum: There are two forms of threading and glue injection, which are energy-saving, heat-insulating, solid and beautiful.
Aluminum Alloy: aluminum alloy is a kind of metal material, so there is no need to worry about aging. This material is relatively strong, impact-resistant and strong, but the heat insulation performance of aluminium windows is relatively weak, because metal itself belongs to the transmission conductor of heat energy, it will transfer the outside temperature to the room with the frame of window decoration. Extrusion molding, good decorative effect, poor heat preservation and high energy consumption.
Plastic Steel: It is a kind of plastic material, so the weight of the material is small, it has good heat insulation performance, and the price is relatively low, because Windows often face the wind and sun, therefore, some friends will worry about the aging of plastic-steel windows, but in fact, high quality plastic-steel windows can be used for about one hundred years.
