The World Health Organization(WHO) recommends an ambient noise level of below 35dB for a good night's sleep.

Solar radiant energy entering a room through the glass is absorbed by interior objects and surfaces, which then retransmit the energy as thermal radiation, mainly in the far infra-red band.?

Condensation forms very differently depending on whether it is inside or outside the building, due to the thermal bridge effect around the cavity. Surface condensation on the internal face always starts in the corners, mainly due to the additional cooling caused by the thermal bridge.

In certain circumstances, the colors of some materials, when exposed to direct sunlight, can fade.? Materials can change color when exposed to solar radiation. The most efficient way of preventing fading is to exclude ultra-violet radiation, since despite its low proportion within the electromagnetic spectrum, it is the main contributory factor to the process.

You may need to choose the glass product?according to?the local building regulations. Normally in the north region of China, it is cold and severe cold area, then the lower U- Value?becomes the most?important?factor for you when choose the glass.?
