What good weather resistance means

Look for this

  • Minimal water absorption (won't swell or warp)
  • Good drainage channels in the frame
  • Tight gaskets against driving rain
  • UV stability against sun

Questions

Frequently asked

Does uPVC profile absorb water?

Quality uPVC absorbs very little, so it doesn't swell or warp in monsoon and humidity — a marker of a sound, weather-resistant profile.

Why does low water absorption matter?

It means the profile won't swell, warp, or degrade in wet conditions, unlike timber — important for monsoon climates.

How is weather resistance achieved?

The profile provides water resistance; fabrication adds drainage and sealing to complete it.
