Prefabricated House with Panoramic Floor-to-Ceiling Windows

The use of panoramic floor-to-ceiling windows in prefabricated houses may pose issues such as safety hazards, poor privacy, heat insulation and ventilation problems, high costs, and risks in extreme weather conditions.

Safety hazards: Although tempered glass has relatively high strength, it has a self-explosion rate, with about 3 out of every 1000 pieces potentially self-exploding. Large-area glass has poor wind pressure resistance. In high-rise residential buildings under extreme wind pressure, window frames may detach or glass may break. For example, in a wind disaster in Hubei, multiple high-rise residential buildings had their panoramic floor-to-ceiling windows sucked away by negative pressure, resulting in casualties.

Poor privacy: Residents on lower floors who install panoramic floor-to-ceiling windows may face the 'glass showcase' effect, where indoor activities are easily visible to the outside world. Even if smart dimming glass or privacy curtains are used, there may still be issues of insufficient light transmittance or poor effectiveness, failing to fully protect privacy.

Heat insulation and ventilation problems: In summer, panoramic floor-to-ceiling windows absorb a large amount of heat, causing a significant increase in indoor temperature. At the same time, their ventilation performance is poor, usually with only small windows on both sides that can be opened, resulting in poor air circulation and potentially affecting indoor air quality.

High costs: The complete installation cost of panoramic floor-to-ceiling windows can be as high as tens of thousands or even hundreds of thousands, and they have extremely high installation accuracy requirements. If the sealant is not properly handled, it can easily lead to problems such as water leakage and air leakage, further increasing maintenance costs.

Risks in extreme weather: In tornadoes or severe convective weather, panoramic floor-to-ceiling windows can become a fatal hazard. Their full-length, undivided glass design lacks a buffer barrier, making it easy for people and objects to be sucked out of the windows, seriously threatening life safety.

In conclusion, the use of panoramic floor-to-ceiling windows in prefabricated houses requires comprehensive consideration of multiple factors and careful assessment of their applicability.
