1. Good windows should have smooth alignment, perfect and flat paint surface and smaller wood color difference. Aluminum clad wood doors and windows the overall thickness should be appropriate. The overall thickness of the profile should not be less than 14mm. Otherwise, the external aluminum strength will be too low. In the process of use, the external aluminum will be deformed or fall off, which will affect the use of Windows.
2. Sealing rubber strip should have good elasticity, flexibility and aging quality resistance. At the same time, the adhesive strip at the corner should be installed tightly, and the linear line should be smooth, so it is necessary to distinguish and increase the strength and air tightness.
3. In terms of operation, the hardware structure must be weight capacity strong, and it must be opened and closed flexibly, and the lap should be rigorous, with good air tightness and hydrophobic performance, and the hardware installation should be firm and not allow hand shaking, it can be easily turned on and off.
4. The diagonal connection of glass layering and wood layering should be closely connected. First of all, the gap should not be greater than 0.5mm, and it needs to be flat and cannot have sculptural feel; Secondly, the angle of the 45-degree angle of the outer aluminum should be flat and there should be no uneven bump phenomenon blocking the hand, the relative gap is less than 0.5mm.
5. Observe the paint. The choice of paint must be the special paint for doors and windows. At present, the market situation needs to use water-based paint, which should have good texture and tightness, and should also resist UV yellowing and fading, and it should be sprayed evenly without color difference and dust-free particles, and the color difference at the wood joint should be controlled within 0.2 °.
