Most of the doors and windows in the market are broken bridge windows and plastic steel windows. How about their sound insulation effect? The editor will teach you to use the following four points to identify them!
I. Selection of door frame materials
at present, most of the real estate development and commercial products are mainly plastic-steel doors and windows, and aluminum alloy is relatively less. However, the air tightness of aluminum alloy is much higher. At the same time, plastic-steel doors and windows are easily deformed by heat, when cold, it becomes brittle, and the stability of size and shape is relatively poor. It is often necessary to use the steel property of glass to prevent the deformation of window frames, while aluminum alloy has the advantages of high temperature resistance, not easy to deform, etc, therefore, the suggestion of the editor is to choose aluminum alloy profile doors and windows.
2. Hollow aluminum strip
the more gaps in everyone's common sense, the worse the sealing performance. This common sense is right, but some manufacturers still use more than aluminum strip splicing, how is the specific sealing effect? Everyone must know that we use one-time bending, which means a aluminum strip one-time bending. One-time bending can achieve only one interface, in order to ensure air tightness.
3. Selection of adhesive strips
everyone may have encountered the phenomenon that door and window rubber strip is separated, because the rubber strip used for doors and windows does not have the performance of high temperature resistance and cold resistance, and will naturally fall off after thermal expansion and cold contraction, when buying doors and windows, you must see clearly or ask clearly. Now, the EPDM and composite adhesive tape that are being used by oprifa doors and windows, whether it is the cold in the north, or the high temperature in the South can adapt to the image without falling off.
4. Tempered glass
now the most commonly used single-sided glass is in the family, and it is not tempered. The better one is the double-layer tempered insulation glass. If you are soundproof, if the heat insulation requirement is not high, it is OK to choose double-layer tempered insulation glass. If you have high requirements on sound insulation and heat insulation effect, you can choose three-layer hollow tempered glass doors and windows, it will definitely achieve your expected results!
