Stormy extreme weather Door and window safety is the key
With the intensification of climate change and the frequent typhoons hitting my country's coastal areas, since July, there has been an increase in rainfall across the country and continuous heavy rainfall. Faced with the "double crit" of typhoons and rainstorms, inferior doors and windows are prone to problems such as blowing and falling, glass breaking, window frame deformation, and rain infiltration when they encounter typhoons.
Door and window safety
The power of nature is irresistible, and we cannot stop the arrival of natural disasters such as typhoons. However, a high-quality door and window can keep the wind and rain out and ensure home safety.
Watertightness
The so-called water tightness refers to the performance of doors and windows that can pass rainwater under simultaneous wind and rain. Generally speaking, watertightness is related to the structural design of doors and windows, the cross-section and material of the rubber strips, and the drainage system. Watertightness can be divided into 6 levels. The higher the level, the stronger the waterproof performance.
Airtightness
It refers to the ability of the edges of doors and windows to prevent external airflow from penetrating. Good airtightness is a protection for building structures with external insulation. Air tightness is divided into 8 levels. The higher the level, the smaller the heat loss and the more prominent the energy-saving effect.
Wind pressure resistance
When closed, the ability of external doors and windows to not be damaged or dysfunctional under wind pressure is very important. Wind pressure resistance is divided into 9 levels. The higher the level, the stronger the wind pressure resistance.
Good water tightness allows doors and windows to effectively block outdoor rainwater from entering when facing heavy rain, keeping the room dry. Our doors and windows adopt a hidden drainage design, citing the concept of the isobaric cavity, and design drainage holes on the side of the window sash. The stepped drainage will not accumulate water in the cavity. The whole window integrates waterproofing, water blocking, water collection, stepped waterproofing, and anti-backflow as a system drainage structure, which can make drainage smoother even in heavy rain.
Air tightness = the ability of doors and windows to prevent air infiltration. Our doors and windows use imported one-piece bending strips, combined with anti-shrinkage fibers, to ensure that the strips fit perfectly with the glass for a long time, solving the problems of cracking of glue and shrinkage and leakage of strips. When heavy rain comes, it effectively blocks the entry of outdoor rainwater, prevents water seepage and leakage, and keeps the room dry at all times.
Wind pressure resistance is particularly important for high-rise residential buildings. The wind pressure resistance of doors and windows mainly depends on the profiles of doors and windows. Our doors and windows use a mature and stable corner assembly and glue injection process, using German two-component corner assembly glue and cross-section glue, and are standardly equipped with high-strength cast aluminum corner codes and cast aluminum flat sheets, which further improve the strength of doors and windows.
