uPVC Window Drainage Explained

uPVC Window Drainage Explained — here's a clear, practical explanation.

How uPVC windows drain water

uPVC frames have small drainage channels and weep holes that let any water that gets into the frame escape outward rather than pooling — important in monsoon.

What to know

Look for this

  • Drainage channels in the frame
  • Weep holes let water escape outward
  • Prevents water pooling inside the frame
  • Important for monsoon performance
  • Kept clear for proper function

Why it matters for your windows

Good drainage, built into the frame and kept clear, is part of what keeps monsoon rain out. We build it in when we fabricate and it needs only occasional clearing.
