In winter, windows in the home will be tested not only against theft, but also against the cold. Especially in the older regions, where windows are not close and warm enough, the winter winds snuck in. What are the doors and windows to protect against cold and how should consumers be selected? Journalists have visited。
At the end of the year, watch out for thieves under the window. Hands
After the theft, liu qing was initially prepared to install a cheaper guard fence. However, after consulting with the family and consulting with professionals, liu qing learned that the outside window was also an escape route and that the fences had stopped him at a dangerous time。
Without the fence, liu qing intends to replace all the doors and windows at home. “replacement of doors and windows is a huge project that will affect the renovation of the home.” is liu qing wondering whether it is possible to change doors and windows in such a difficult manner that they will eventually serve as a protection against the cold?
In a large shopping mall in the frou district of changsha city, journalists have seen more than 40 businesses running doors and windows. “in recent years, the number of brands of doors and windows has increased and products have been constantly updated.” according to mr. Dauphin, some of the new doors and windows were different from those provided by developers. On the market, there are various types of broken-bridge aluminium alloy doors and windows, aluminium bunging doors and windows, and plastic steel windows。
New types of doors and windows are expensive
Among them, aluminium alloys in and around the broken-bridge aluminium alloy doors and windows are separated and connected with thermal materials through the break-out process. Added to the double-storey glass structure, it acts as an insulation against cold. At the same time, outside such aluminium alloy doors and windows, consumers can also install veiled windows. Special metal windows cannot be broken or easily severed and can act as a deterrent to theft. "our windows are multiple locks, so they're safer." another businessman, mr. Chen, who operated the new window, said that he was not the only one who had a business。
As journalists have seen, this new type of door and window material process varies, and prices vary. Of these, the price of broken aluminium alloy doors and windows was $1,900/m2. “most of the buyers of these doors and windows are the owners of villas and mansions.” mr. Chen stated that higher prices were prohibitive for many consumers。
Countries do not have standards for this type of product
Are the doors and windows equipped by developers protected from theft? Are the new ones guaranteed? In the case of the house-buying contract between the owner and the developer, the examiner, li jiae, an inquisitor at changsha city real estate information and consulting ltd., told the reporter that, in general, only entry into the house was agreed to as a high-level security door and that the specific branding of the doors and windows would not normally be agreed. During the examination, only the materials and openings of doors and windows are examined。
In addition, journalists have learned that there are currently only national standards for the prevention of burglary (gb 1998-17565), which regulates such features as “the most vulnerable security doors can resist the irregular opening of net working hours”. However, the standard is only for the security doors and not for the windows。
Industry warns that, as there are no corresponding standards for regulation in the country and industry, consumers need multiple comparisons, experience and careful selection when purchasing anti-piracy windows。
