Siliguri homes range from older single-story bungalows near the Mahananda River to newer apartments along Sevoke Road, all facing constant high humidity and heavy June-September rains that swell wooden frames. Installers routinely replace windows already warped or mold-stained after just a few monsoon cycles, using reinforced UPVC profiles with extra drainage channels to handle the Terai downpours. Temperature swings between hot summers and cooler winter nights near the hills also cause seal failures on standard windows, requiring precise expansion joints during fitting.
UPVC Window Installation in Siliguri — What We Handle
- ✓Extra drainage and sealing for Siliguri's prolonged monsoon rainfall
- ✓Dust-resistant installation methods for tea-estate and traffic areas
- ✓Wind-load considerations for upper-floor units near the hills
Kolkata's older concrete-framed buildings in areas like North Kolkata and Howrah often have uneven openings from decades of monsoon exposure and settlement. UPVC frames with multi-chamber profiles and proper EPDM gaskets create a tight seal that reduces water ingress during heavy July rains while cutting heat gain in summer. Installers must check lintel condition and add steel reinforcements when sills show spalling before fixing new frames.
Newer apartments in Salt Lake and New Town use larger openings that benefit from reinforced mullions and low-E double glazing to handle both intense afternoon sun and high indoor humidity. Without correct drainage channels and weep holes, water can pool behind the frame during prolonged showers, leading to mold on interior walls. Experienced crews always slope the outer sill and apply neutral-cure silicone at the junction with external plaster.
