Koho sound insulation doors and windows dev13 sound insulation doors and windows

  Koho soundproof doors and windows adopt the third generation of steel aluminum plastic coextrusion profiles as the frame, which avoids the problem that the first generation of aluminum plastic coextrusion profiles become brittle and easy to be damaged in winter
At the same time, it improves the shortcomings of the second generation of aluminum plastic coextrusion profiles in surface treatment and sealing, and improves the profile structure, making the third generation of aluminum plastic coextrusion profiles more beautiful, solid and durable, with better sealing performance and thermal insulation performance In terms of processing and manufacturing, the third generation of steel aluminum plastic coextrusion profiles adopted by dev sound insulation doors and windows follow the processing method of welding + corner code of the first generation of aluminum plastic coextrusion profiles
The processed whole window has a more stable and reliable structural strength, and the wind pressure resistance level has been improved to a greater extent
Due to the use of original coextrusion sealing materials, there is no need to insert additional sealing strips, which effectively ensures the sealing effect of the processed dev sound insulation doors and windows Koho sound insulation doors and windows use professional dev sound insulation glass or DT energy-saving sound insulation glass as door and window glass, which forms a good match with the frame of steel aluminum plastic coextrusion window
The sound insulation performance of the whole window of standard dev13 sound insulation doors and windows can reach 37db to 39db, and the sound insulation volume of the whole window of dev sound insulation doors and windows designed with small open leaves and large fixed windows can reach 42db, The sound insulation loss is only 1 dB lower than that of dev sound insulation glass Dev13 soundproof doors and windows have excellent isolation effect on annoying noises such as traffic noise, human voice and square dance music, and have good sound insulation and noise reduction effect on high decibel heavy truck, aircraft noise, high-speed rail trains, ship whistle and large-scale high-noise equipment
