Doors and windows are divided into enclosure members or partition members according to their positions. There are different design requirements to have functions such as heat insulation, heat insulation, sound insulation, waterproofing, and fire protection. New requirements for energy saving. The lost heat accounts for about 25% of the total heating consumption. With the improvement of the economic level, people's requirements for doors and windows have also increased. Next, I will introduce the door and window equipment to you-the requirements for materials:
Wood: easy processing and repair, more light blocking, excellent thermal insulation performance, easy deformation of solid wood, high-grade laminated wood for wood windows.
Steel: Standard steel window material (solid web, empty web) is strong and durable, fireproof, less light blocking, economical, poor maintenance, easy to rust, and poor thermal insulation performance.
Stainless steel: excellent decorative effect, no rust, high cost.
Aluminum alloy: extrusion molding, good decorative effect, poor thermal insulation, high energy consumption ...
Plastic steel: good comprehensive performance and high cost performance.
Broken bridge aluminum: There are two forms of threading and glue injection, energy saving, heat insulation, strong and beautiful.
Glass: It is often used to make indoor partitions and frameless pop-up doors.
FRP, which is glass fiber reinforced material, is a new type of composite material. It has many advantages such as light weight, high strength, corrosion resistance, thermal insulation, insulation, sound insulation and so on.
