Since 2011
uPVC & Aluminium windows built for Indian homes
Delight Windows has spent more than a decade solving the same three problems — heat, noise and dust.
We started in 2011 with a single fabrication line and a simple idea: a window should be specified for the wall it sits in, not picked from a catalogue. Today we run our own manufacturing unit, our own installation crews and our own service team.
Every profile is multi-chambered and lead-free, every joint is machine-welded, and every unit is sealed with EPDM gaskets rather than silicone alone. That is why our windows still shut cleanly after a decade of Delhi NCR summers.
Why uPVC
Six reasons homeowners switch
The performance you actually notice after moving in.
Energy Efficient
Multi-chambered profiles and insulated glazing cut heat transfer, so air conditioning works less.
Noise Insulation
Sealed double glazing with EPDM gaskets reduces street noise by up to 40 decibels.
Rainwater Sealing
Sloped drainage channels and dual gaskets keep monsoon water outside where it belongs.
Low Maintenance
No painting, no polishing, no rusting. A wipe with soap water is the entire routine.
Dust Resistant
Compression seals and tight tolerances stop the fine dust that ruins Delhi NCR interiors.
Weather Resistant
UV-stabilised, lead-free profiles that do not yellow, warp or crack in 45°C summers.

uPVC Windows & Doors Manufacturer in Gurgaon and Delhi NCR
Delight Windows is a manufacturer and supplier of uPVC windows, uPVC doors, aluminium windows and aluminium doors serving Gurugram, Delhi, Noida, Faridabad, Ghaziabad and the wider North India belt. Our product range covers sliding, casement, tilt-and-turn, combination, bay, French, top-hung, fixed and arch systems in every standard and custom dimension.
Each profile is UV-stabilised for tropical exposure and reinforced with galvanised steel, so frames resist warping, corrosion, acid rain and heat gain. Combined with double glazing and multi-point locking, the result is a window that lowers your cooling bill, keeps dust out of a main-road flat and shuts as smoothly in year ten as it did on day one.
Whether you are building a villa in Sohna Road, retrofitting an apartment in DLF Phase 4 or specifying a commercial tower in Manesar, our team will measure the openings, recommend the right system and install it with our own crew.

Client feedback
What homeowners say
Reviews from families and businesses across Delhi NCR.
We live on a main road and had given up on quiet. The acoustic double glazing Delight recommended made a genuine difference from the first night. What impressed me more was that they measured, manufactured and installed with their own team — one number to call throughout.
Rohit Malhotra
Homeowner · Sector 57, Gurugram
I have specified their uPVC on four projects now. The finishing is consistent, they hold the dates they commit, and they will happily fabricate a non-standard arch or bay instead of talking the client out of it. That last part is rare.
Anjali Verma
Interior Designer · New Delhi
Thirty years of repainting wooden windows is finally over. They copied the old profile so closely that neighbours did not notice the change until I pointed it out. Two monsoons in, not a drop of seepage anywhere.
Capt. S. Bedi (Retd.)
Villa Owner · Sushant Lok, Gurugram
Our west-facing floor was unusable after lunch. The reflective double-glazed units they installed dropped the zone temperature by around four degrees and our chiller load with it. The install ran over weekends so we lost no working days.
Meera Nair
Facilities Head · Sector 44, Gurugram
Straightforward pricing, no last-minute additions, and the crew cleaned up properly at the end of each day. The modular kitchen came six days ahead of the promised date.
