Doors and windows are an indispensable part of the living room. Up to now, doors and windows have experienced four eras of wood, steel, aluminum alloy, plastic steel doors and windows. The price of wooden doors and windows is moderate, the appearance is poor, the sealing is poor, the fire is flammable, the deformation is cracked, and it is only suitable for low grades. It is suitable for general places, high maintenance cost and short service life.
Steel welded doors and windows are low in price, low in grade, easy to corrode, easy to deform, high in maintenance cost, short in service life, and facing elimination. Aluminum alloy doors and windows have good flame retardancy, luxurious appearance but poor overall performance, easy to deform, easy to corrode, poor heat preservation, poor heat insulation and low sound insulation effect.
Compared with wooden doors and windows and steel doors and windows, aluminum alloy doors and windows have the following characteristics:
1, light weight, sturdy and durable. Aluminum alloy doors and windows are about 50% lighter than steel doors and windows; they are more resistant to corrosion than wood doors and windows, and are not easily eroded. Their oxidized colored layers do not fall off, do not fade, and are durable.
2, good sealing performance. Aluminum alloy doors and windows have high air tightness, water tightness and sound insulation are better than wooden doors and windows and steel doors and windows.
3, the color is clean and beautiful. The frame material of the aluminum alloy door and window is treated by ammoniating and coloring, and can be colored in white, bronze or dark red, and can be colored with a pattern. The aluminum alloy doors and windows made of the same have a beautiful appearance, a smooth surface, a bright and firm color, and enhance the decorative effect of the indoor façade.
The single-layer glass-separated plastic steel doors and windows are the fourth generation of doors and windows after wood, steel and aluminum alloy. The performances of heat preservation, fire resistance, waterproof, anti-corrosion and sound insulation are unmatched by wooden windows, steel windows and aluminum alloy doors and windows. The price is moderate, the appearance is luxurious, the style is diverse, the sealing is good, the fire retardant, the deformation is not easy, the strength is good, the installation is convenient, the craft is stressful, and it is a new generation of door and window materials, which has broad prospects.
Here are some simple methods to check the installation quality of plastic steel doors and windows.
1 Look at the window surface: the window frame should be clean, smooth, smooth, no scratches or bumps on the large surface, and the profile is not broken.
2 Look at the hardware: the hardware must be complete, the position is correct, the installation is firm, the use is flexible, and the respective functions can be achieved.
3 Look at the glass sealing strip: the contact between the sealing strip and the glass and glass notch should be flat, and it should not be curled or undulated.
4 Look at the sealing quality: When the door and window are half-closed, there is no obvious gap between the fan and the frame, and the sealing strip on the sealing surface should be in a compressed state.
5 Look at the glass: The glass should be flat and firmly installed. There should be no looseness. The single-layer glass should not be in direct contact with the profile. The inner and outer surfaces of the double-layer glass should be clean. There should be no dust or moisture in the glass interlayer, and the spacers should not be lifted.
6 Look at the bead: the bead with the sealing strip must be in close contact with the glass. There should be no obvious gap between the bead and the joint of the profile. The joint gap should be less than or equal to 1 mm. Push-pull.
7 Look at the puzzle: the splicing material should be tightly connected with the window frame, and sealed with the caulking paste. It should not be disturbed. The screw spacing should be less than or equal to 600 mm. Both ends of the reinforced steel should be firmly fixed to the hole.
8 Look at the switch components: Swing, push-pull or rotating windows should be closed tightly.
9 The frame is connected to the wall: the window frame should be horizontal and vertical, the height should be consistent, the spacing of the fixing piece should be less than or equal to 600 mm, the frame and the wall should be firmly connected, the gap should be filled with elastic material, and the surface seal is sealed. No cracks.
10 Look at the drain hole: the drain hole should be in the correct position and at the same time be smooth.
