uPVC Window Price in Nepal 2026
In 2026, uPVC window price in Nepal commonly ranges from around Rs. 700 to Rs. 1,500+ per sq ft. The final cost depends on profile quality, glass thickness, hardware, lock system, and whether it is sliding, casement, or fixed window.
uPVC is usually preferred by homeowners who want better insulation, lower maintenance, and good sealing for dust and noise. It is practical for bedrooms, study rooms, and homes near busy roads when paired with good glass and proper installation.
Aluminum Window Price in Nepal 2026
Aluminum window price in Nepal commonly ranges from around Rs. 650 to Rs. 1,800+ per sq ft. Normal aluminum sections can be budget-friendly, while premium aluminum systems with better hardware, powder coating, thicker section, and better sealing can cost much more.
Aluminum is popular for modern house façades because it allows slimmer profiles, larger openings, and a cleaner architectural look. Premium aluminum is a good choice for living rooms, balcony-facing windows, commercial buildings, and modern elevation designs.
Which Is Better for Kathmandu Homes?
For many Kathmandu homes, the practical answer is: use the material based on room and design requirement instead of choosing only one system for the whole house.
- For bedrooms: uPVC can be better because of insulation and noise control.
- For large front elevation windows: aluminum often looks better and handles larger panels well.
- For budget rental floors: normal aluminum or basic uPVC can both work depending on supplier rate.
- For premium homes: premium aluminum or high-quality uPVC with good glass and hardware is recommended.
Hidden Costs to Ask Before Ordering Windows
- Glass thickness and glass type
- Lock, roller, handle, and hardware quality
- Mosquito mesh cost
- Installation charge
- Silicone, sealant, and finishing work
- Transport and lifting to upper floors
- Warranty and after-sales service
uPVC vs Aluminum: Final Recommendation
If your priority is noise control, dust sealing, and insulation, choose good-quality uPVC. If your priority is modern elevation, slim profile, large openings, and premium look, choose good-quality aluminum. In both cases, do not compromise on glass, hardware, and installation quality.
