Window glass tips help you easily choose

When buying a house for decoration, it is necessary to seal the balcony windows. Many consumers are confused about the selection of doors and windows. Because some glasses look the same, why is the price so far different? This leads to consumers in the purchase of doors and windows, do not know how to start. Today, Guanhao door and window editor will share some common sense of door and window glass with us

aluminum alloy door and window glasses include general glass, single-layer tempered glass, hollow general glass and hollow tempered glass

general glass

general glass: also known as float glass, because the thickness of float glass is uniform, the upper and lower surfaces are flat and parallel, and it is economical. It is a kind of glass commonly used in aluminum alloy golden doors and windows. The thickness of door and window glass is 5mm as stipulated by the state

characteristics of general glass: economical, and its defects: poor safety, poor sound insulation

single layer tempered glass

tempered glass: it is the glass made of general glass through reprocessing, which is mostly used in places with high safety requirements

features of tempered glass:

① high safety: even if the tempered glass is broken, the fragments will form small obtuse angular particles similar to honeycomb, which is not easy to cause severe damage to the human body

② strong impact resistance: the impact strength of tempered glass with equal thickness is 3 ~ 5 times that of ordinary glass, and the bending strength is 3 ~ 5 times that of ordinary glass

③ thermal stability: tempered glass has good thermal stability, the acceptable temperature difference is 3 times that of ordinary glass, and the temperature difference change of 300 ℃ is acceptable

hollow general glass

hollow general glass: use the bonding method to stick to a certain distance between the two general glasses. The distance is dry air, and the surrounding is sealed with sealing materials. It is mainly used in places with high requirements for sound insulation

hollow general glass features: good sound insulation, its defect: poor safety

hollow toughened glass

hollow toughened glass: the bonding method is often used to adhere to a certain distance between the two toughened glasses. The distance is dry air, and the surrounding is sealed with sealing materials. It is mainly used in places with high requirements for sound insulation

hollow tempered glass features: good sound insulation, good safety and strong impact resistance

the materials of several commonly used energy-saving tempered glass (a kind of safety glass produced by tempering furnace) are mainly coated glass, insulating glass and thin-film heat reflective glass. Generally, the construction of doors and windows accounts for more than 40% of the construction energy consumption. For example, the coated glass mainly includes solar thermal reflective glass, low radiation glass and multifunctional coated glass
