There are many problems in street shop products
At present, the types of windows on the Beijing market are mainly made of plastic steel and aluminum alloy. According to the way of opening, it is mainly based on push-pull and peace-opening. In terms of price, the average price of plastic steel window is more than 300 yuan. The price of aluminum alloy windows is relatively expensive.
The author saw in several formal building materials markets that the window frame fans were very regular, there were no obvious scratches and cracks on the surface, and the handles and hardware accessories were very firm. In the small door faces on the street, most of the windows sold here are rough and have no formal quality and safety signs. In particular, the color of the plastic steel window is yellowish white (the normal plastic steel window is blue-white). Experts have warned that this kind of plastic-steel window with yellow in the white is that some manufacturers have added some additives in order to reduce the cost, and the products are greatly reduced in strength and service life.
Consumers choose domestic window
The author saw that the windows of the same material, the price of domestic brands and imported brands have a difference of several hundred yuan. A salesperson of an imported window brand told the author that the raw materials for their windows were imported from Germany, and the price of hardware on the windows alone was between RMB 300 and RMB 400. Consumers who buy windows at the side have also shook their heads and said they would not choose such windows. "The same material, style of the window, or the domestic price is relatively cheap, I can accept. Import is too expensive, I think it is not necessary." Many consumers think so.
Expert advice
Choose more than seven floors
Wang Wei, deputy secretary-general of the Beijing Construction Hardware Door and Window Industry Association, told the author that the first choice is to choose a regular brand of products. It is necessary to check whether the manufacturer of the product has the legal production license qualification, and whether the product has the “QS†logo and the environmental protection label.
Before installation, pay attention to check whether the window frame fan is regular, whether the joint is firm, whether the glass is intact, whether there is obvious corrugation, whether the handle and the metal fitting are firm, the surface of the hardware should be fine and not rough, and the distance between the double glass should not be less than Whether the 8mm drain hole is blocked or the sealant strip has the smell of a punctured nose.
After installation, please pay attention to check whether the whole window is deformed, whether the window sash is flexible, whether the window and the wall are firmly connected or not, and the protective film attached to the surface of the window material should be removed in time.
He also suggested that households with more than seven floors should not install windows that are sashed outwards to prevent the wind from scraping off the sash.
Expert advice
Household windows must be energy efficient
On the purchase window, Deputy Secretary-General Wang suggested that consumers choose windows with good energy-saving insulation performance. Generally speaking, the function of the energy-saving heat preservation window is to block the outdoor heat energy in the summer to save the electric energy consumed by the air conditioner, that is, to save the electricity cost; in the winter, the indoor heat energy is left indoors to save the energy and cost consumed by the heating.
According to experts, the use of energy-saving insulation windows can increase the room temperature by about 3 °C during the heating season. This kind of energy-saving and heat-insulating window has high comfort and can bring great benefits to consumers.
Float glass has better performance
At the same time, consumers should choose good glass when choosing windows. At present, the external windows produced by regular manufacturers mainly use float glass and low-emission coated glass. According to experts, float glass is much better than flat glass in terms of heat insulation, heat preservation, light transmission and avoiding visual distortion; low-emission coated glass has better quality in heat insulation, heat preservation, light transmission and ultraviolet light removal. Therefore, when replacing the outer window, consumers should consider using float glass and low-emission coated glass as much as possible.
Consumption tips
Choose windows should shop around
When I visited several building materials markets, I noticed that the window prices of the same brand are not exactly the same in the various building materials markets. The author noticed that the price of a window brand in the middle and high-end building materials market is more than 1,000 yuan, while the price of a middle and low-end building materials market is half as cheap. Therefore, when consumers choose a window and choose it in the formal building materials market, they should also make more comparisons on the price to avoid spending money.
