Choose cold knowledge that you may not know about bridge cutting aluminum
At present, the most popular and mainstream doors and windows in the market are no more than broken bridge aluminum doors and windows. This material has excellent comprehensive effects in terms of insulation, environmental protection, and noise prevention, and is therefore favored by many customers.
However, the prices of broken bridge aluminum doors and windows in the market are very chaotic. As the saying goes, seeking small gains can lead to great losses. Today, let me take a look at the most mainstream doors and windows in the current market.
Choosing bridge cutting aluminum is actually very simple, only three key points are needed: profiles, glass, and hardware.
Profile
The profiles are divided into 60, 70, 80, 110, 130, and so on. These numbers refer to the width of the profiles, and the focus of insulation and insulation is related to the size of the profiles, but the relationship is not absolute. The 70 and 80 series of commonly used broken bridge aluminum profiles for home decoration are mostly used, and as for the 130 screen window integrated design, it may not be more suitable.
Although wall thickness and thermal insulation are not the most influential conditions, they directly affect the stability of bridge cut aluminum doors and windows. The new national standard has been raised to 1.8, so as a household choice, it should not be lower than the old national standard 1.4. With sufficient budget, the thicker the better.
glass
1. Tempered glass
Tempered glass is divided into: two-layer hollow, two-layer hollow+Low-e, three-layer hollow glass, three-layer hollow+Low-e, double-layer laminated, and laminated hollow glass.
If you live on the downtown street and dance in the downstairs square is loud, we suggest you choose laminated insulating glass, which can effectively isolate the noise outside the house and restore your own peace.
If you value the insulation effect more, you can choose a three-layer insulating glass with three glasses and two cavities. The cavities between the glasses are filled with argon gas, which can effectively prevent heat loss. If you have a need for UV protection, you can add Low-e to isolate UV rays. Ordinary glass is divided into ordinary silver edge and high-end warm edge, which can be selected according to your own needs.
2. Insulation strip
The insulation strip is an important condition for whether the aluminum window of the bridge is insulated. The insulation strip should be made of nylon material. PVC will deform, fall off, and leak after aging, and how to distinguish it is also very simple. Just pick it up and fold it back and forth, and the PVC will turn white after a few folds, or use a lighter to burn it without igniting it.
The specifications of the broken bridge aluminum door and window adhesive strip: imported EPDM products, with a service life of 30 years, while low-quality products only have a service life of about 5 years. Silicone weather resistant adhesive should be used for sealant.
Distinguishing the authenticity of adhesive strips: first look, second smell, and third stretch. The color of the genuine adhesive strip is pure black, with no bumps on the surface and good density; Smell: Normal rubber odor, the odor should be non pungent and not strong; Stretch: Strong tensile force, elastic, and not easily folded.
