Customers may be curious about why the price of vacuum glass is higher than that of insulating glass. Following this article, you will find the reasons.
✦Vacuum glass has excellent thermal insulation performance, using it as window glass can quickly warm the room in winter, and the indoor heating is not easy to dissipate. In summer, the indoor air conditioner makes it difficult for the air-conditioning to escape.
✦Due to its good thermal insulation performance, vacuum glass does not reduce the surface temperature of indoor window glass in winter, and the cold feeling between the window and the sole of the foot due to the "surface wind" is alleviated. Warm in winter and cool in summer, vacuum glass makes room warm and comfortable.
✦Vacuum glass is used as exterior window glass, with its extraordinary sound insulation performance, it prevents noise interference and realizes a quiet environment. The sound insulation performance (>35dB, up to 45dB) can fully meet the requirements of Shanghai "Notice on the use of sound insulation windows for new buildings within 50 meters on both sides of the road", and is suitable for existing and planned expressways and main road red lines. Newly built residential buildings, schools, hospitals and other buildings within 50 meters from the side of the street should be installed on the exterior windows of the buildings along the street. It is difficult for ordinary glass (single-piece glass (<18dB) and insulating glass (<25dB) to achieve good noise reduction effect.
The thermal insulation performance of vacuum glass is based on the principle of vacuum thermos. The thermal insulation effect of ICESUN vacuum glass products exceeds that of a 1meter thick brick wall, which is 4~6 times that of ordinary insulating glass, and the U value (also called heat transfer coefficient or K value) is as low as 0.4-0.6W/m2·K.
The sound insulation and noise reduction performance of vacuum glass is based on the fact that sound does not travel under vacuum conditions. The weighted sound insulation of ICESUN vacuum glass reaches 38dB-42dB, and the weighted sound insulation of general insulating glass is about 28dB. With ICESUN vacuum glass, the interior is as quiet as a library, even at airports, viaducts or main roads.
Note: The higher the weighted sound insulation, the better the sound insulation effect. For example, the outdoor noise is 75 decibels, after using ICESUN vacuum glass, the indoor sound is 36 decibels (75-39=36), and the library is generally below 40 decibels.
