Pit-avoidance guide: Five questions to teach you how to choose thermally-broken aluminum doors and windows
If you want to change windows and seal balconies, but you don't understand these five questions order thermally broken aluminum doors and windows. I can only say that you are stupid and have a lot of money. The editor tells you that if you have the need to change windows and seal balconies.
First, don't ask the merchant if there is a 108 thermally-broken bridge as soon as you enter the door. Smart people ask: Is this thermally broken aluminum window processed locally or in Foshan? Is it original aluminum or recycled aluminum? Although recycled aluminum looks fine on the surface, it is not hard enough and is easy to deform over time.
Second, don't easily believe what the merchant says about the system window. Many merchants don't even understand what the real system window is. Most consumers choose two sealing structures. If there are higher requirements for sound insulation, heat insulation, and thermal insulation, it is best to choose a three-sealed product.
Third, the insulation strip is supposed to be as wide as possible, but we want it. We should adapt to local conditions. Just like the climate in our north and south regions is different, I suggest that for families with floor heating, and fresh air systems or located in southern cities, 20 mm insulation strips are enough. On the contrary, for families with floor heating and fresh air systems located in the north, 20 to 30-mm insulation strips should be used.
Fourth, the choice of glass. If you just want to seal a balcony and don't want to change the windows of the developer, you can use two-shot hollow tempered glass. If you want to reduce ultraviolet rays, you can choose ordinary glass. Do you know why I don't recommend you spend money to choose three-glass two-cavity or laminated hollow glass? If you are doing a broken bridge aluminum window for the whole house and want better insulation and heat preservation, choose three-glass two-cavity, or ordinary glass. If you are near the road viaduct and have low-frequency noise problems, choose laminated hollow glass.
Fifth, there are many categories of gold hardware, but the quality varies. You must distinguish between imported and imported hardware brands because these are two. It is a completely different concept. Imported hardware brands are domestically made. If you can't tell the difference, choose domestic first-line hardware brands. A good piece of hardware also depends on whether it has multiple lock points. It is common to have only two lock points on the handle, but high-end broken bridge aluminum windows will have lock points on the upper and lower positions of the opening and the handle. Hardware is a good partner for sealing strips. The more lock points, the tighter the sealing strip is pressed, and the better the sealing performance, especially the larger points on the opening must have more.
