Heavy-Duty Commercial UPVC Sliding Window

Heavy-Duty Commercial UPVC Sliding Window Systems Overview | BLOSSOM CHEER

Engineered for multi-family resorts, our heavy-duty UPVC sliding windows combine steel-reinforced interlocks and tandem rollers for effortless gliding and 450Pa water tightness.

Key Benefits of Heavy Duty Commercial UPVC Sliding Windows | BLOSSOM CHEER

2.0mm Steel-Reinforced Interlocks Withstanding 2,500Pa Wind Pressures

Heavy structural steel inserts inside interlocking mullions prevent frame deflection across wide 3-meter spans in storms.

Stepped Windproof Sill Tracks Resisting 450Pa Water Penetration

Tiered high-low sill channels and pressure-equalized weep valves evacuate rainwater rapidly, preventing water pooling and leakage.

Tandem Bearing Rollers Delivering Smooth Sliding Under 15N Force

Precision sealed bearing rollers glide along tracks effortlessly, providing quiet fingertip motion for heavy double-glazed sashes.

Integrated Anti-Lift Security Blocks Eliminating Derailment Risks

Concealed top anti-lift stops prevent sashes from being jacked upward, securing building perimeter envelopes against break-ins.
