Broken bridge aluminum doors and windows adopt heat insulation broken bridge aluminum profiles and insulating glass, which have the functions of energy saving, sound insulation, noise prevention, dust prevention, waterproof and so on. The thermal conductivity K value of broken bridge aluminum doors and windows is 3W / ㎡ Below K, the heat loss is reduced by half compared with ordinary doors and windows, the heating cost is reduced by about 30%, the sound insulation is more than 29 dB, and the water tightness and air tightness are good, which all meet the national class A1 window standard.
1. Profile wall thickness: for general home decoration products, the national standard wall thickness shall not be less than 1.4mm, and the specific thickness shall be selected by the designer. Then those with wall thickness less than 1.4mm belong to non-standard products;
2. Thermal insulation strip: thermal insulation strip is the most critical component of bridge broken aluminum profile. The state stipulates that PA66 nylon strip must be used. Some manufacturers in the market use cheap PVC plastic thermal insulation strip, which will affect the service life of products;
3. Glass: Bridge broken aluminum doors and windows must adopt hollow glass with different thickness. The original piece is float glass, and the thickness standard is 5mm. The thickness of the heat insulation strip between the two pieces of glass is 12mm-15mm, which is set according to the specifications of door and window profiles;
4. Door and window adhesive strips: EPDM products shall be selected for the adhesive strips, with a service life of 30 years, while the service life of ordinary inferior products is only about 5 years.
