Best uPVC Window Brands in India (2026): How to Choose

Written by the Stylfixx team · Reviewed by Omar Sharieff, Director, Stylfixx Innovations Pvt. Ltd. · Last updated 9 November 2026

Short answer: The best-known uPVC window brands in India include Fenesta, VEKA, Kömmerling, REHAU, Aluplast, Deceuninck, LX Hausys (formerly LG Hausys), Aparna Venster, Prominance and Encraft. There is no single best brand. Most uPVC windows are built by a local fabricator from one brand's profiles, so the fabricator's welding, steel reinforcement, hardware and installation matter as much as the name on the frame. Choose a reputable profile, then judge the fabricator and the window itself.

This guide explains how uPVC windows are made and sold in India, compares the main brands, gives a seven-point quality checklist and 2026 Bengaluru prices, and is honest about where uPVC is not the best choice.

Profile brand vs fabricator: who actually makes your window

A uPVC window starts as long hollow lengths of plastic called profiles, made by an extrusion company. A fabricator then cuts the profiles to your sizes, inserts steel reinforcement, welds the corners, fits the gaskets, hardware and glass, and installs the window.

In India you will meet three set-ups:

• Brand makes and installs: some companies, such as Fenesta, extrude their own profiles and also fabricate and install through their own network.
• Profile brand plus authorised fabricator: global profile makers such as VEKA, Kömmerling and REHAU supply profiles to independent fabricators who build and fit the windows.
• Local fabricator with any profile: a contractor buys profiles from a brand or distributor and makes the windows. Quality varies most here, for better and worse.

The brand name tells you the quality of the plastic. It does not tell you whether the corners were welded cleanly, whether steel was put inside the frame, or whether the window was fixed square and sealed. Ask who will fabricate and who will install.

uPVC window brands in India compared

The table is not a ranking. It lists facts published by the brands or trade directories. Warranty terms differ by product, so get the profile warranty in writing from the brand and the fabrication warranty from the installer.

Seven things that decide uPVC window quality

1. Profile wall thickness. Under the European standard EN 12608, Class A profiles have visible walls at least 2.8 mm thick and Class B at least 2.5 mm. Ask which class the profile meets; thin-walled profiles flex and lose their seal.
2. Steel reinforcement. Galvanised steel inside the frame and sash keeps long windows straight in summer heat and holds the screws for hinges and locks. Ask to see it in a cut section.
3. Lead-free and UV-stabilised. Good profiles use calcium-zinc stabilisers instead of lead and enough UV protection that white frames don't yellow or chalk in the sun.
4. Chambers and gaskets. Multi-chamber profiles insulate better. Look for double gaskets that are continuous around the sash.
5. Hardware. Multi-point locks on casements, stainless or coated rollers on sliders, and handles that move smoothly. Cheap hardware is the first thing to fail.
6. Glass. 5 mm clear glass for most rooms; double-glazed units for noise and heat; toughened or laminated glass for large panes, doors and ground-floor safety.
7. Installation. The frame fixed square with proper anchors, the gap foamed, and the outside joint sealed with silicone. A good window badly installed still leaks.

uPVC window prices in Bengaluru (2026)

Typical installed prices per sq ft of window, including profile, reinforcement, glass, hardware and fitting:

The profile brand, window size, number of tracks, glass, grills, colour (white or laminated wood finish) and hardware change the price. Very small windows cost more per sq ft because hardware is a fixed cost. See our uPVC windows and doors page for what's included.

Disadvantages of uPVC windows

uPVC suits most homes, but it has real limits:

• Bulkier frames than aluminium. uPVC needs thicker sections for strength, so you get slightly less glass area and a less slim look.
• Limits on very large openings. Floor-to-ceiling sliders and wide spans are often better in aluminium or need heavy reinforcement.
• Fewer colours. White is standard. Wood-grain and coloured laminates cost more, and the profile cannot simply be repainted.
• Cheap profiles age badly. Poorly stabilised profiles yellow, chalk or warp in strong sun. This is a quality problem, not a material one, which is why the checklist above matters.
• Thermal movement. uPVC expands more than aluminium in heat. Without steel reinforcement and proper fixing gaps, long frames can bow.
• Harder to repair. A cracked or damaged profile usually means replacing the sash or frame; aluminium can sometimes be repaired.

uPVC vs aluminium windows

For most Bengaluru flats and houses, uPVC is the better all-round choice. Choose aluminium where you want very large or very slim openings.

Buying uPVC windows in Bengaluru

• Dust and traffic noise: if you face a main road or metro line, choose casement windows with good gaskets, or double glazing; sliders leak more sound and dust.
• Monsoon rain: check that sliding tracks have drainage slots and that the outside sill and silicone joint are sealed, or water will collect inside the track.
• West-facing rooms: double glazing or solar-control glass cuts afternoon heat.
• Mosquitoes: a sliding mesh track on sliders, or fixed mesh on casements.
• Ground floors and independent houses: add internal grills or laminated glass for security.

Questions to ask before you order

1. Which profile brand and series, and which EN 12608 class?
2. Who fabricates the windows, and is the fabricator authorised by the brand?
3. Is galvanised steel reinforcement used in every frame and sash?
4. Which hardware brand, and are casements fitted with multi-point locks?
5. What glass will each window get, and is it toughened where it needs to be?
6. What warranty covers the profile, the hardware and the installation, and who honours each one?
