Street shop product problems

At present, the types of windows on the market are basically plastic-steel and aluminum-alloy materials. According to the way of opening, there are two kinds of push-pull and peace. In terms of price, the price of ordinary steel windows is more than 300 yuan. Aluminum alloy windows are relatively expensive.

The author saw in several regular building materials markets that the window frame fans are very regular and there are no obvious scratches and cracks on the surface, and the handles and hardware accessories are very firm. In the street, a few small door faces saw that most of the windows sold here were rough and had no formal quality safety signs. In particular, the color of the plastic window is yellowish-white (the normal plastic window is blue-white). Experts have warned that this kind of white plastic window with yellow is added by some manufacturers to reduce the cost of some additives, the product is greatly reduced in strength and service life.

Consumers choose more domestic windows

The author saw that the window of the same material, the price of the domestic brand and the imported brand's window was even a few hundred dollars. A salesperson of the imported window brand told the author that the raw materials for their windows were all imported from Germany, and the price of the hardware on the windows was only between 300 and 400 yuan. Consumers who shop around the window also shook their heads to indicate that they would not choose such a window. "The same materials, style windows, or domestic prices are relatively cheap, I can accept. Imports are too expensive, I think there is no need." Many consumers think so.

Expert advice

Seven-storey homes choose to open outside the window

First of all, we must choose the products of the regular brand. We must pay attention to checking whether the manufacturer of the product has the qualification for legal production license and whether the product has the “QS” logo and the environmental protection logo.

Before installation, check whether the window frame fan is regular, whether the joints are firm, whether the glass is complete or not, whether the handles and metal fittings are firm, the surface of the hardware should be delicate and not rough, and the distance between the double glass should not be less than Whether the 8mm drainage hole is blocked or if the sealant has a pungent nose.

After installation, attention should be paid to checking whether there is deformation of the whole window, whether the sash opening is flexible, whether the window is firmly connected with the wall surface and whether there is a firm gap, and whether the protective film attached on the surface of the window material is peeled off in time.

He also suggested that tenants living in seven-storey or higher buildings should not install windows with window sashes opening outwards to prevent high winds from scraping the sashes.

Expert Weapon

Home windows must be energy efficient

On the purchase window, Deputy Secretary-General Wang suggested that consumers choose windows with good energy-saving and heat-insulating properties. In general, the function of the energy-saving heat preservation window is to block the outdoor heat energy in the summer to save the power consumed by the air conditioning, which is to save the electricity fee; in the winter, the indoor heat energy is left indoors to save the energy and expenses consumed by the heating.

According to experts, the use of energy-saving insulation windows can increase the room temperature by about 3°C ​​in the heating season. This kind of window that saves energy and keeps warm is highly comfortable and can bring great benefits to consumers.

Float glass performs better

At the same time, consumers should choose good glass when choosing windows. The exterior windows produced by regular manufacturers are now mainly made of float glass and low-emissivity coated glass. According to experts, float glass is much better than flat glass in terms of heat insulation, heat preservation, light transmission, and visual deformation. Low-e coating glass is superior in heat insulation, heat preservation, light transmission, and ultraviolet light filtration. Therefore, when replacing the outer window, consumers should try to consider the use of float glass and low-emissivity coated glass.

Consumer tips

Choose windows to shop around

When I visited several building materials markets, I noticed that the same brand of window prices are not exactly the same in all building materials markets. The author noticed that the price of a certain window brand in the high-end building materials market is more than 1,000 yuan, while the price of a low-end building materials market is half as cheap. Therefore, when choosing a window, consumers should make comparisons in price when selecting products in the formal building materials market, so as to avoid spending money.
