How to select windows & doors glass?

2024.10.17

The selection of windows & doors glass should consider safety (Tempered Glass), energy saving (LOW-E Glass), sound insulation (Laminated, Multi-cavity insulating glass), light transmission and aesthetics. Also pay attention to the thickness of the glass, the thickness of the hollow layer and the quality of the brand.

In modern home decoration, the choice of windows & doors is crucial, and the glass of windows & doors is a key factor in determining its performance. Whether from the perspective of safety, energy saving, sound insulation or aesthetics, choosing the right  windows & doors glass is a learning. Below several key points for selecting glass:

1. Safety: the first choice tempered glass

Safety is the primary consideration when choosing glass for windows & doors. Ordinary glass often forms sharp fragments after breaking, which is easy to hurt people.

Tempered glass through controlled heat treatment or chemical treatment, so that its surface strength is greatly improved, even if broken will form small obtuse particles, greatly reducing the harm to the human body.

Therefore, when purchasing glass, it is necessary to choose tempered glass with professional certification to ensure the safety of use.

2. Energy efficiency: LOW-E glass is preferred

With people's attention to energy conservation and environmental protection, LOW-E glass has gradually become the new favorite.LOW-E glass, that is, low-radiation coated glass, a film system composed of multiple layers of metal (silver) or other compounds plated on the surface of plain white or ultra-white glass, can reflect 99% of solar thermal radiation and ultraviolet radiation, while retaining 80% of light transmission.When choosing, you can choose single silver, double silver or even three silver LOW-E glass according to regional climate characteristics and personal needs, the more silver layer, the better the energy saving effect.

3. Sound proof: laminated glass and multi-cavity insulating glass

Sound insulation performance is an important part of windows & doors glass. Laminated glass has high safety because of the interlayer between two or more layers of glass that can fix the debris, even if the glass breaks, it can be kept together.

Sound insulation effect of laminated glass is better than that of single cavity insulating glass. The multi-cavity insulating glass further improves the sound insulation performance by increasing the number and thickness of the hollow layer.

For places that require high sound insulation requirements, such as bedrooms, study rooms, etc., laminated glass or multi-cavity insulating glass can be given priority.

4. Light transmission and aesthetics

The light transmission and beauty of windows and doors glass are also important points that cannot be ignored. Good permeability of the glass can ensure that the indoor light is sufficient, even in rainy weather will not feel dim.

In the selection, you can pay attention to the light transmission index of the glass, and whether it has anti-fog, anti-ultraviolet and other functions. In addition, with the improvement of home aesthetics, more and more consumers are beginning to pay attention to the beauty of door and window glass.

For example, frosted glass, long rainbow glass and other glass products with special texture can not only protect privacy, but also add a hazy beauty and artistic atmosphere to the home space.

5. Others

1) Glass thickness and area ratio: according to the national standard requirements, the area and thickness ratio of large glass should be controlled within a certain range.E.g.: the maximum safe area of 5mm thick glass is 2 square meters, and 6mm corresponds to 3 square meters. For large glass areas, it is recommended to choose laminated glass to enhance safety.

2) Thickness of the hollow layer: the hollow layer of insulating glass is not thicker, the better. After the test, the thickness of the hollow layer of 12mm is more appropriate, which can ensure the sound insulation effect and avoid waste.

3) Brand and quality: choose well-known brands of windows & doors glass products to ensure product quality and after-sales service. At the same time, when purchasing, we should carefully check the product test report and certification certificate to ensure that the indicators meet national standards.

So the selection of suitable windows & doors glass needs to be comprehensively considered from many aspects such as safety, energy saving, sound insulation, light transmission and aesthetics. Hope it’s useful.
