Due to the many advantages of high-end aluminum alloy doors and windows, many owners are willing to choose it. However, in many high-end products, there are always some fish in troubled waters. What skills do we have to identify these products?
Look at the style
Reasonable window type selection brings you beautiful and practical feeling, but there are many styles of doors and windows. You can listen to the suggestions of professionals according to the housing structure, and then choose freely combined with personality.
Look at the materials
The thickness, strength and oxide film of aluminum profiles used for high-quality aluminum alloy doors and windows shall comply with the relevant national standards. The wall thickness shall be more than 1.2 mm, the tensile strength shall be 160 n / m2, the yield strength shall be 110 n / m2, and the oxide film thickness shall be 10 μ M.
Look at the craft
High quality aluminum alloy doors and windows, fine processing, exquisite installation, good sealing performance, switch freely.
Look at the price
In general, the price of high-quality aluminum alloy is about 30% higher than that of inferior aluminum alloy doors and windows due to its high production cost. The tensile strength and yield strength of some aluminum alloy doors and windows made of aluminum profiles with wide section and thin wall thickness are much lower than the relevant national standards, so they are not safe to use.
Look at the window surface
The window frame shall be clean, flat and smooth, and the surface shall be free of obvious scratch, bruise and fracture of profile.
Look at hardware
There is no obvious gap, and the gap at the joint shall be no more than 2mm. The hardware should be complete, the position is correct, the installation is firm, the use is flexible, can achieve each function.
Look at the glass
The glass shall be flat and firmly installed without looseness. The glass shall not directly contact the profile. The inner and outer surfaces of the glass shall be clean. There shall be no dust and moisture in the double-layer or insulating glass interlayer, and the spacer strip shall not be cocked.
Look at the pieces
The splicing material should be closely connected with the window frame, and sealed with caulking paste. The screw spacing should be ≤ 600mm.
Look at the sticker
The pressure strip with sealing strip must be tightly attached to the glass.
Look at the glass color
The glass of aluminum alloy door and window can choose green glass, because green is most suitable for human eyes in terms of wavelength, which is beneficial to human vision. Brown glass installation in the bedroom more appropriate, because it is more gentle, give a warm feeling
Look at the drain hole
The position of drain hole should be correct and unobstructed at the same time.
Look at the sealing quality
When the doors and windows are closed, there is no obvious gap between the fan and the frame, and the sealing strip on the sealing surface should be in the compression state.
Look at the switch parts
Flat open, push-pull and folding doors and windows shall be closed tightly.
Look at the way of wind guide
Generally, push-pull windows can be installed for windows in the north-south direction, casement windows should be installed for windows in the east-west direction, lifting windows should be used in toilets, medium suspended windows should be used for ventilation, and casement windows should not be installed in pedestrian passageways.
Look at the glass seal
The contact between the sealing strip and the glass and the glass notch shall be smooth, and the edge curling and groove shedding are not allowed.
The above are some useful skills to distinguish true and false high-end aluminum alloy doors and windows. More skills are accumulated in our daily life. Only when we accumulate more, we will feel comfortable when we use them.
