Monsoon tests a window's sealing and drainage. Here's what keeps rain out and lasts through years of wet seasons.
uPVC doesn't rot, rust, or swell, so it's unaffected by prolonged damp — unlike timber, which can warp, or steel, which corrodes. This makes it a natural monsoon choice.
Good gaskets keep wind-driven rain out, and drainage channels in the frame let any water that does enter escape rather than pool. Both are essential for monsoon performance.
Casements seal tightest against driving rain. Sliders perform well with quality interlocks and drained tracks. Either works when properly specified and fitted.
Not when properly specified and fitted — gaskets seal against wind-driven rain and drainage channels clear any water that enters. uPVC itself is unaffected by water.
Casements seal tightest against driving rain; sliders also perform well with good interlocks and drained tracks.
No — uPVC doesn't rot, rust, or swell, which is a key advantage over wood and steel in a wet climate.
