Performance Advantages

Air and Water Tightness Performance

With 700Pa water tightness and 1.2 m³/(m·h) air tightness ratings, the WY-118L window system restricts moisture and air infiltration under heavy rainfall conditions. This level of sealing performance supports consistent indoor climate control for commercial buildings in coastal or high-precipitation regions.

Wind Pressure and Sound Insulation

Rated for 5K Pa wind pressure resistance and 35 dB sound insulation, the WY-118L casement window maintains structural stability under strong wind loads while reducing external noise transmission. These properties support use in high-rise commercial structures and buildings located near traffic corridors.

Thermal Insulation and Energy Efficiency

The WY-118L window achieves a U-factor of 0.23 and SHGC of 0.20 when configured with double tempered glass filled with argon gas. These thermal values contribute to reduced heating and cooling loads, supporting lower operational energy costs for commercial facility management.
