‍‍ from April 11th to 12th, many areas in Henan province were hit by extreme winds of force 15. The scene of entire floor-to-ceiling Windows being uprooted from high-rise buildings by the strong wind has pricked the public's nerves about living safety. In the recent strong wind disaster in Henan Province, the doors and Windows of high-rise buildings were particularly severely damaged.

Videos circulating on social media show that the floor-to-ceiling Windows of a certain household were distorted and deformed in the strong wind, with the glass instantly shattering and flying. Behind these scenes lies a deep-seated issue in the safety design of building facades - can the wind pressure resistance and sealing performance of doors and Windows withstand extreme tests?

Structural defects exposed by wind disasters

01. Weak corner connection: Ordinary corner codes are prone to delamination in strong winds, causing the overall displacement of the window frame

02. Simple crimping fixation: Relying solely on the adhesive tape for bonding, it cannot withstand the alternating impact of positive and negative pressure

03. Single-layer tempered glass: Insufficient impact resistance, prone to cracking due to wind pressure fluctuations

The direct cause of the damage to a large number of doors and Windows in this disaster lies in the lag of design concepts. Traditional doors and Windows often pursue transparency and cost control, but neglect the structural strength requirements under extreme weather conditions.

The impact resistance shortcomings of single-pane glass, the load-bearing limitations of simple hardware, the incomplete filling of corner sealant, and the sealing of profile joints, among other issues, make many Windows less exposed under normal weather conditions. However, they may become fatal flaws in 15-level wind forces. The damage to the physical structure also poses a fatal blow to the psychological defense of the residents.

The core logic of wind pressure resistance technology

A truly reliable door and window system requires the establishment of multiple defense mechanisms at the design stage, and living safety needs to be upgraded in tandem with climate change. The technical path of Bosni Doors and Windows focuses on three key dimensions:

01. Structural rigidity strengthening: By optimizing the internal support system of the profile, the overall anti-deformation capacity is enhanced. Under the same wind pressure, the optimized structure can disperse the stress throughout the entire frame, avoiding the risks caused by local stress concentration.

02. Dynamic sealing Balance: By adopting multi-stage sealing technology, an elastic adjustment space is formed in the face of pressure fluctuations caused by strong winds. This not only prevents the penetration of wind and rain but also alleviates the impact and vibration of wind pressure on the window frame.

03. Upgraded installation stability: From wall anchoring to corner joining process, each step has been strengthened in accordance with the characteristics of high-altitude wind force. Especially in high-rise buildings, the connection strength between doors and Windows and the main structure of the building directly determines the wind resistance performance.

True quality lies in keeping a product silent even under extreme conditions - because its mission is to keep danger at the door.

After the disaster, many places have launched safety inspections of building facades. I hope everyone will not be deceived by superficial concepts. It is the core parameters of profiles, glass and installation that can truly save lives when a storm comes.
