UPVC Windows
STRONG DOORS. SAFE SPACES.
Precision-engineered multi-chamber UPVC windows with galvanized steel reinforcement, double glazing, and monsoon-proof drainage. Superior energy savings, acoustic quiet, and cyclone wind protection.
Engineered UPVC Windows
DORPRIME™ UPVC windows are designed to solve the harsh weather challenges of Indian climates. Extruded with lead-free virgin UPVC compounds and internally reinforced with galvanized steel, they never crack, warp, or corrode from heat or humidity.
Featuring hermetically sealed fusion-welded corners, stepped drainage sills, and continuous EPDM compression gaskets, our windows prevent rainwater ingress and draft leakage while keeping outdoor heat and street noise outside.
Key Advantages of DORPRIME™ Windows
Built for tropical Indian weather with zero maintenance, monsoon sealing, and energy efficiency.
Monsoon Proof & Zero Leakage
Built-in graduated drainage channels and continuous compression seals ensure zero water penetration even during heavy monsoon downpours.
Thermal Insulation (Cuts AC Bills)
Multi-chamber design traps dead air, blocking outdoor solar heat and reducing indoor air conditioning electricity consumption by up to 40%.
Acoustic Noise Reduction (40 dB)
Double glazing and airtight gaskets cut street honking, loud highway traffic, and neighborhood commotion for peaceful living spaces.
High Wind & Cyclone Resistance
Reinforced with internal galvanized steel cores, our windows withstand severe wind gust pressures up to 2,500 Pa (180 km/h wind speeds).
Integrated Mosquito Flyscreen
Available with built-in Grade 304 stainless steel insect mesh tracks, allowing refreshing natural ventilation while keeping pests out.
Zero Painting & UV Anti-Yellowing
Formulated with high titanium dioxide (TiO2) to prevent yellowing or chalking in harsh sun. Never rots, rusts, or requires repainting.
