broken bridge aluminum doors and windows what are the advantages?
In addition to the advantages of heat preservation and energy saving, broken bridge aluminum doors and windows it can also effectively reduce noise. The multi-cavity structure of insulating glass with different thickness can isolate noise of about 35 decibels by multi-point contact foaming of soundproof and flow blocking cotton. At the same time, the material of broken bridge aluminum is high in strength, not easy to deform, and the service life can be as long as 50 years. Its air tightness and water tightness are obvious to all, which can block wind, sand and dust, and is the first glare of many high-rise owners.
What broken bridge aluminum doors and windows OK?
1. Look at the series
broken bridge aluminum doors and windows there are different series, such as: Broken Bridge aluminum 60/70/80/90/108 series. The difference between these figures lies in the width of the profile section. 60 series represents a material width of 6cm, similarly: 70 series is 7cm, 80 series is 8cm......
The larger the number of series, broken bridge aluminum doors and windows the better the thermal insulation effect? NO! This is a misunderstanding. If the merchant tells you that the 70 series is better than the 60 series thermal insulation, it must be that he is cheating you. The larger the number of bridge-cutoff aluminum alloy doors and windows series, the wider the corresponding window frame and the higher the price, but the better the thermal insulation performance is not necessarily.
2. Look at the heat insulation strip
impact broken bridge aluminum doors and windows there are many aspects of thermal insulation performance, and the heat insulation strip is one of the important points.
Look at the material of heat insulation strip: is it cheap PVC or high quality nylon 66 heat insulation strip? The material of heat insulation strip is broken bridge aluminum doors and windows the basic guarantee of quality, now many unscrupulous merchants shoddy. In order to reduce the cost, they will use inferior PVC insulation strips to fill up, and the heat insulation effect is very small.

look at the size of the insulation strip: the larger the size of the empty insulation strip, the higher its insulation performance.
Look at the shape of the heat insulation strip: One-shaped, also called I-shaped heat insulation strip, its heat insulation performance is not as good as that of C font heat insulation strip. I-shaped groove is easy to accumulate water, soaked with adhesive strips, and the adhesive strips are easy to age. C font is more expensive, but the cavity-type heat insulation strip has the best heat preservation performance.
3. Look at the wall thickness
famous Brand broken bridge aluminum doors and windows the wall thickness is 1.4mm, which is the national standard for aluminum profiles, unknown broken bridge aluminum doors and windows most of the profiles are between 1.0-1.2mm wall thickness, which cannot reach the national standard. Naturally, its wind resistance and compression resistance will be worse.
4. Look at the glass
if you want good heat insulation and sound insulation, choose hollow glass. There are several specifications of broken bridge glass hollow glass, generally 5 9A 5,5 12A 5,5 20A 5,5 27A 5. Among them, the sound insulation performance of 5 9A 5 is the worst, and the sound insulation performance of 5 27A 5 is the best, and their general price difference is 30-40 yuan. Beware of the merchant's cute act, for example, it was originally 5+12+5 glass, but 4.3 glass was used instead of 5 glass, guangguang can make merchants earn 50 yuan per square meter. Tempered glass should be sure whether there is a 3C certification mark. If the sealant looks like a dog gnawing, Pass it quickly.
5. Look at the hardware
to choose brand hardware, ask the merchant when purchasing, "What brand is your hardware?". If the merchant's reply is original hardware or original hardware, it must be hardware produced by a small workshop, and the quality will not be good. If the merchant answers big-name or imported hardware, it sounds good, but be sure to ask whether all the hardware or just the handle is worth it according to the quotation given by the merchant.
