Energy saving aluminium alloy window be careful to choose
Aluminum alloy doors and Windows because of light weight, high strength, good performance, decoration use strong, durable, color diversity economy, no pollution, can recycle and become China’s main building doors and Windows of our products are widely used in public buildings from high-end to the general civil residence and industrial plants. Energy-saving aluminium alloy window of aluminium sliding window profile is heat insulation, energy saving and glass, hollow glass, low-e glass, absorption of glass, coated glass, vacuum glass, etc) is made and be become.
When the choose and buy need to pay attention to:
First of all: see material pledge. If the heat insolation aluminum, the main profile is greater than 1.4 mm thick wall to; The same root aluminium alloy profile colour and lustre should be consistent, such as color difference obvious, which is unfavorable to choose; Check the surface of aluminium alloy profile, there shall be no depression or drum out; Aluminum alloy doors and Windows avoid the choose and buy has an open surface bubbles (white) and ash (black spots), and crack, burr, peeling and the obvious flaw profiles; Oxidation film thickness should achieve 10 microns, can be in when the choose and buy the material surface under a light, see its surface oxidation film whether it can be erased.
Next: see quality of manufacture and assembly quality. Door window decoration surface should not have obvious damage, it refers to the surface of the door window should not scratch scratch protective film of trace. The aluminum alloy tilt and turn window adjacent component surface colouring should not have clear off color. Door window should not have the surface of aluminum powder, burr, staining or other stains, assembly joint should not have spillover of the adhesives.
Repeated switch many times, to check whether the power switch overweight; Article seal whether firmly; Hardware assembly is all ready; Casement window frame lap a quantity to whether meet the requirements (standard casement Windows not less than 6 mm, push-pull window not in 8 mm).
Finally: see the glass. If hollow glass, have the coating.
Plastic doors and Windows are gradually replace aluminum alloy doors and Windows.
2 now heat preservation, seal, energy saving, environmental protection, price advantage plastic doors and Windows has accounted for 50% of the national doors and Windows utilization rate, plastic doors and Windows are gradually replace aluminum alloy doors and Windows.
At present domestic plastic door toward a high energy saving, the industry is color doors and Windows and high-grade door window type enterprise three direction. As each big building dish to the increase of the individual requirements, plastic doors and Windows color also gradually from a white development for very colorful.
Through to the plastic doors and Windows of chamber increase and improve the performance of seal, plastic doors and Windows of the insulation energy-saving effect continue to increase, “in recent years as a new technology, PVC plastic folding door and Windows in the insulation, corrosion resistance and seal performance are beyond traditional aluminum alloy doors and Windows. We understand that at present the south plastic doors and Windows utilised for 45%, in the north plastic doors and Windows utilization rate has reached 70%.”
