OUR PHILOSOPHY
Vision, Mission & Values
Our Vision
To see a Sikkim where homes are no longer defined by the cold or damp outside, but by the warmth and silence inside. We envision a future where world-class insulation is the standard for every hill home.
Our Mission
To bridge the gap between European technology and Himalayan needs. We exist to manufacture high-performance windows locally, ensuring that every family in Gangtok has access to affordable, climate-engineered comfort.
Our Values
We don't just build windows; we live here. We know the rattling of tin roofs and the chill of January. Every product we fabricate is designed to solve the specific problems we face daily in the hills.

The Proview Advantage
Redefining Construction in Sikkim
We noticed that standard uPVC windows installed in Sikkim were often failing within a few years—yellowing under UV rays or leaking during high-pressure monsoons. The problem wasn’t the material; it was the ‘one-size-fits-all’ approach.Proview was built to change this. We don’t just fabricate windows; we reinforce them for the Himalayas. We use specific UV-stabilized profiles and heavy-duty hardware calculated to withstand the unique wind loads and temperature drops of our altitude.
We use heavy-duty steel reinforcements inside the frame to prevent warping under high wind pressure.
Our materials are chemically treated to resist the harsh mountain sun, preventing that ugly yellowing over time.
We pay obsessive attention to gasket installation, ensuring your home stays 100% draft-free in winter.
Based in Gangtok for immediate support.
