For home decoration balcony large glass, ensuring safety and wind pressure resistance requires consideration of multiple factors. Below are some specific measures and suggestions:
I. Glass material and thickness
Choosing high-quality glass:
Tempered glass: The self-explosion rate is about 3‰, but for every 1㎡ increase in single-piece area, the self-explosion risk increases by 20%. Therefore, when choosing tempered glass, the balance between its area and self-explosion risk needs to be considered.
Insulated glass: For extreme weather areas or high-rise sealing windows, insulated glass is recommended. This type of glass not only has good sound insulation but also is not easy to hurt people when it breaks. The lamination is divided into dry lamination and wet lamination. Dry lamination is recommended because the latter has poor anti-aging ability.
Extra-clear glass: Large glass is prone to self-explosion, and choosing extra-clear glass can reduce the self-explosion rate. Extra-clear glass has high light transmittance, few impurities, and a self-explosion rate lower than 3%.
Increasing glass thickness:
Large glass has a large area and weight, and it bears greater wind pressure. Therefore, it is necessary to select glass according to the standard of glass area and thickness. Especially in high-rise buildings or areas with high wind pressure, thicker glass is a wise choice.
For example, when the area of a single piece of glass exceeds the conventional size (such as ≥4.5㎡), extra-thick glass (12mm) or an upgrade to a laminated/insulated composite structure is required.
II. Window structure and installation
Break-bridge material and profile structure:
The break-bridge material needs to have good thermal insulation performance. PA66GF25 material is recommended, which has good thermal insulation performance.
The profile structure should be selected with extended edge reinforcement and heightening to ensure that the large glass is safe and stable, with no risk of collapse.
Multi-point support profile structure can effectively prevent the deformation and cracking of profiles or break bridges caused by overweight large glass.
Closable pressure line:
Large glass accounts for more than 80% of the window area, and the tightness of the combination of glass and profile directly affects the wind pressure resistance performance of the window.
The role of the pressure line is crucial. If the pressure line is loose, the glass may fall down, and even rainwater may leak in rainy days.
It is recommended to choose a hook-type wind pressure line, using the principle of force and reaction force mechanics to ensure high pressure strength and strong clamping ability, thereby improving the wind pressure resistance performance of the window.
Professional installation:
Ensure that the window is firmly installed to avoid loosening or falling off during long-term use.
During installation, it is necessary to operate strictly according to the specifications to ensure that each step meets safety standards.
III. Other safety measures
Filling inert gas:
Glass with an area exceeding 2.5 square meters must be filled with inert gas such as argon to prevent the suction phenomenon inside the hollow glass caused by excessive air pressure.
Regular maintenance:
Regularly inspect and maintain the windows to ensure that they are in good working condition.
If damage or safety hazards are found in the windows, they should be repaired or replaced in time.
Buying insurance:
Consider purchasing related insurance for home-decorated balcony large glass to deal with possible accidents.
In summary, ensuring the safety and wind pressure resistance of home-decorated balcony large glass requires a multi-faceted approach. By choosing high-quality glass, optimizing window structure and installation, adopting other safety measures, and regular maintenance, the safety and wind pressure resistance performance of home-decorated balcony large glass can be greatly improved.
