How to choose doors and windows on the same floor? Floor-by-floor selection guide from the first floor to the top floor

First floor (lower level)

Challenges: dampness, high noise, many mosquitoes, high demand for security.

Glass is preferentially laminated insulating glass, providing both sound insulation and explosion protection; optional with protective grille style, window screens use high-transparency diamond mesh; the profiles have multi-chamber insulated breaks, preventing dampness and condensation.

Middle floors (3-10 floors)

For daily household use, standard insulated aluminum profiles + insulating Low-E glass are the standard; for those near the road, the glass is upgraded to thicker type to balance cost-effectiveness and practicality.

High-rise buildings above 10 floors

Wind pressure is the key factor. The profile wall thickness is ≥ 1.8mm. Large floor glass requires thickened glass + stainless steel counterweight; standard features include anti-drop hardware and limiters, prohibiting inferior thin-profile profiles; in typhoon-prone areas, an enhanced frame structure can be selected.

Roof floor

Large temperature differences and severe sun exposure. The entire window is equipped with high-thermal insulation PA66 insulation strips + shading Low-E glass to reduce heat absorption during summer and water leakage during winter.
