uPVC windows Bangalore apartment owners install today are fully compatible with RCC (Reinforced Cement Concrete) structures, which are the standard construction method across Bengaluru.
Whether you live in a high-rise apartment, gated community, or standalone flat, your building almost certainly uses RCC frames. Understanding how uPVC windows integrate with RCC construction is crucial for proper sealing, long life, and zero leakage.
This guide explains how uPVC windows are installed in RCC frames, common challenges in Bangalore apartments, and what homeowners should check before installation.
What Is an RCC Frame & Why It Matters
RCC frames are made of:
- Cement
- Steel reinforcement
- Brick or block infill
They provide excellent structural strength but often come with:
- Slightly uneven wall openings
- Construction tolerance gaps
- Plaster thickness variations
Windows must be custom-made and properly sealed to perform well in RCC structures.
Are uPVC Windows Compatible with RCC Frames?
Yes — uPVC windows are ideal for RCC-frame buildings.
Unlike wooden or aluminium windows, uPVC:
- Is custom-manufactured to exact opening size
- Uses flexible sealing systems
- Adapts well to minor RCC unevenness
- Does not crack or corrode when fixed to concrete
This makes uPVC windows Bangalore apartments prefer a perfect match for RCC construction.
How uPVC Windows Are Installed in RCC Apartments
Step 1: Site Measurement
Professional installers measure:
- Width & height of RCC opening
- Wall depth
- Plaster finish thickness
Accurate measurement ensures:
✔ Tight fit
✔ No gaps
✔ Clean finishing
Step 2: Frame Fixing to RCC Wall
The uPVC frame is anchored using:
- Steel fasteners
- Rawl bolts or screws
- Proper spacing for load distribution
Steel reinforcement inside uPVC profiles ensures strong grip with RCC walls.
Step 3: Sealing & Gap Filling
This is the most critical step for Bangalore homes.
High-quality installers use:
- PU foam
- Silicone sealant
- Weather-resistant gaskets
This prevents:
- Rainwater leakage during monsoon
- Dust entry
- Air gaps
- Noise leakage
Common Problems in RCC Apartments (and How uPVC Solves Them)
❌ Water Leakage During Monsoon
✔ Solved by airtight uPVC sealing + proper slope alignment
❌ Uneven Window Openings
✔ uPVC custom sizing adapts to RCC irregularities
❌ Cracks Around Frames
✔ uPVC flexibility prevents stress cracks
❌ Noise & Dust Entry
✔ Multi-chamber profiles + TPE gaskets block pollutants
Best uPVC Window Types for RCC Apartments

Glass Options Recommended for RCC Buildings
| Glass Type | Why It’s Ideal |
|---|---|
| Toughened Glass | Structural safety |
| Double Glazed Glass | Heat & sound insulation |
| Laminated Glass | Noise + security |
| Low-E Glass | Heat reduction |
👉 Double-glazed Low-E glass is highly recommended for Bangalore apartments near roads or metro lines.
Does RCC Structure Affect uPVC Window Cost?
Not significantly.
Cost depends more on:
- Window size
- Glass type
- Hardware
- Floor height (installation effort)
Approximate Bangalore Pricing:
- Sliding uPVC: ₹450–₹650 / sq ft
- Casement uPVC: ₹550–₹850 / sq ft
- Double-glazed: ₹750–₹1,300 / sq ft
A proper RCC-compatible installation ensures 25+ years of trouble-free performance.
Why Professional Installation Is Critical in Bangalore Apartments
RCC buildings in Bangalore vary widely in quality and finishing.
Professional installation ensures:
✔ Correct frame anchoring
✔ Monsoon-proof sealing
✔ Smooth operation
✔ No structural damage
Poor installation — not the window — is the #1 cause of leakage complaints.
