When you decide to replace doors and windows, the following purchase suggestions may help you make a wiser choice.

First of all, it is recommended to choose heat-insulating aluminum alloy profiles. Compared with plastic steel doors and windows, aluminum alloy materials have high strength, good rigidity, durability, and excellent sealing performance.

Glass is best to use hollow laminated glass. Especially in winter, the sealing of broken bridge aluminum alloy doors and windows is tighter than ordinary doors and windows, and the sound insulation effect is also better. You must look for double-layer laminated glass with 3C certification, which has good heat insulation, sound insulation, anti-frost, condensation, safety and other high performance, and is a warm tool for winter homes.

At the same time, it is also important to pay attention to the energy saving of doors and windows. Non-energy-saving doors and windows are prone to energy loss to the outdoors, increasing energy consumption expenses. Some users still feel cold in winter even though they have floor heating indoors. It may be because the windows have poor sealing performance, low energy saving, and a large amount of energy loss from the windows.

In addition, when purchasing doors and windows in winter, anti-collision details cannot be ignored. If there are children at home, pay attention to whether the corners of doors and windows are rounded, whether the folding doors support the anti-pinch function, etc. Avoid accidentally bumping into the sharp corners of windows at home and getting injured.

The installation link is also critical. Doors and windows are customized products, 30% depends on the product, and 70% depends on the installation. During installation, pay attention to: whether the surrounding area of the window wall is cleaned, otherwise it may affect the effect of waterproof coating and foaming agent; whether the window sill is waterproofed, especially when the width of the window sill outside the old community is large; whether the exposed screws are made of stainless steel, whether the screws at the sliding support and hinge are aligned, whether the window frame is fixed with nylon expansion nails and hit on the aluminum alloy frame instead of the insulation strip, whether the screw installation is standardized, the first screw on each side of the window frame should be less than 18cm away from the edge, and the distance between each screw should not be more than 50cm.

If the budget is limited, there is no need to evenly distribute funds on all doors and windows. You can focus on spaces such as kitchens and bathrooms that do not have high requirements for doors and windows, and ensure that they do not leak or seep water; for bedrooms, study rooms, living rooms and other places that have high requirements for sealing and other performance, you can increase investment appropriately to improve the living experience; for washing and drying balconies and living balconies, they need to be treated differently according to their functionality. If the washing and drying balcony has indoor partitions and only needs to ensure safety, and the cozy living balcony has high requirements for doors and windows, you can refer to the specifications of bedroom doors and windows or even higher standards when choosing.
