Windows and doors, as one of the very important aspects of the house decoration process, not only affect the overall visual effect, but also meet our requirements for room comfort, warmth and safety. Doors and windows integrate a variety of materials such as profiles, hardware, glass and auxiliary materials, etc. The design needs to consider many factors such as aesthetics, structural mechanics and light and heat energy conduction control, noise control, wind pressure resistance, airtightness, watertightness, ease of use, durability, and weathering resistance.
Products need to consider a lot of factors, at the same time the market specification degree is very poor, so we are in the choice of doors and windows, facing the misunderstanding and traps will be a lot of those big factors I think we should all understand, the next step, to give you some details of doors and windows can not be ignored recommendations.
1, look at the corner of the spell
As we all know, the final quality of doors and windows with the processing capacity of the processing plant has a relatively large relationship, one of the important indicators is the corner. Good doors and windows corner of the two profiles are connected with aluminium corner code, and then use the corner grouping machine to extrude the profiles and corner code together, and then inject two-component adhesive in the hole, so that the corner of the frame is cured together. Commonly used low-quality practices are: no corner code splicing, there is a corner code without curing glue, or this is a little in the mouth to deceive consumers. In addition, you can also judge the quality by touching the group corner of the splices with your hand, the smoother it is the better the quality of the group corner processing.
2, look at the rubber strip
In order to ensure the sealing of windows and doors, the system windows and doors use a large number of rubber seals, good seals must be elastic, black colour and not easy to deform. At the glass frame, good doors and windows is the use of adhesive tape, there are many manufacturers are artificial glue. This is not the standard practice of good doors and windows.
3, look at the hardware
For doors and windows, hardware is the most superficial thing, so many doors and windows factory selling points are also in the hardware. The quality of the hardware mainly comes from the reasonable design, appropriate materials and processing fine and so on. In general, many businesses use foreign brands, such as Noto (roto), Shimek, Sigiriya, Goya and Sobinke, etc., of which Noto is the most widely used in China. However, we note that there are many trademarks in the market for “rotc”, the businessman will also say it is Germany Noto.
4, look at the glass
Glass has always been a weak link in home improvement doors and windows, occupying 80% of the entire door and window area, for the realization of the function of doors and windows, occupies an absolutely important role. Many door and window manufacturers will avoid talking about the glass, the main reason is that most of the processing plant is a small factory.
The main functions of glass considered are thermal insulation performance, sound insulation, safety, anti-smash and UV isolation, etc. Glass can get a lot of additional functions after processing, but at present, these technologies can only be mastered by some big factories. There are some points I would like to remind you:
First, thermal insulation mainly relies on LOW-E and hollow to achieve, LOW-E glass is divided into online and offline, offline LOW-E performance from low to high is divided into single-silver, double-silver and triple-silver, online LOW-E in performance is about equal to single-silver. In general, the ordinary glass of three glass and two hollow is not as good as the energy-saving effect of single-cavity glass using LOW-E;
Secondly, hollow does not add much sound insulation, heat insulation is mainly achieved by the intermediate laminated film sheet.
So how can you tell if you are using LOW-E glass?
Generally speaking, the LOW-E film is on the inside (2nd side) of the outdoor piece of insulating glass, carefully look at it from the side, you should be able to see a layer of light blue or greyish film. In addition, I have a secret, with a lighter, close to the glass to see the flame, a flame will have three shadows. On the side with LOW-E film, the third flame shadow glows light blue, the others glow red. While the three flames of ordinary glass are red, the third flame colour is just very light, in the bright light can not be seen. See the picture below:
Above picture is ordinary glass
The picture above shows Low-E glass
In addition, the recent market launch of self-cleaning glass scrub-free windows and doors, through the integration of glass technology and windows and doors technology, so that a window and door, in addition to customising the colour of the aluminium according to the owner’s needs, the most important thing is to have a scrub-free, 99% UV isolation, sound insulation of 41 decibels, double-silver energy-saving Low-E and a certain degree of smashing and shatter-resistant ability, which can maintain the integrity of the glass after the glass is broken.
5, look at the colour
Door and window colour can also be customized. Currently on the market in addition to supporting a variety of colours of surface treatment, but also can be made into a wood grain shape, add metal powder to increase the metal texture and other means. Market acceptance is relatively high is aluminium alloy products, generally fluorocarbon spraying, powder electrostatic spraying, anodic oxidation and surface film and so on. Powder coating is cheap but meets the most requirements. In addition, powder coating can also be done in the interior of the wood grain; in acceptance, in addition to meet the personalised needs, acceptance should also pay attention to the quality of the surface spraying, colour difference, scratches, as well as unqualified phenomena such as paint fall.
The cost of colour customisation is generally charged according to the complexity of the colour treatment, with a typical starting quantity of 20 square metres or more for a single colour.
