High-Performance UPVC Doors

DORPRIME™ UPVC doors are built for modern residences, luxury villas, and commercial buildings. Manufactured with lead-free virgin UPVC profiles and reinforced with internal galvanized steel cores, they offer superior strength without the risk of warping, rotting, or rusting.

Equipped with double-glazed insulated glass and continuous perimeter compression gaskets, our doors create a tight seal that blocks heat, keeps out rain, and significantly dampens exterior street noise.

Why UPVC?

Key Advantages of DORPRIME™ UPVC Doors

Designed for long-term comfort, energy savings, and zero maintenance.

Superior Thermal Insulation

Multi-chamber profiles block outdoor heat, keeping rooms naturally cooler and reducing air conditioning electricity bills.

Acoustic Noise Reduction

Double-glazed insulation and airtight perimeter seals cut traffic honking, street noise, and urban disturbance.

Monsoon & Weather Proof

Fusion-welded corner joints and continuous EPDM gaskets prevent water leakage and air drafts even during heavy rains.

100% Termite & Rot Proof

Unlike timber, virgin UPVC will never rot, warp, swell, or get infested by termites. Completely rust-proof in coastal areas.

Multi-Point Security Locking

Equipped with high-security multi-point locking mechanisms for enhanced burglar resistance and perimeter compression.

Zero Painting Maintenance

UV-stabilized profiles never require painting, polishing, or varnishing. Clean effortlessly with standard soap and water.
