uPVC Multi-Point Locking Explained

uPVC Multi-Point Locking Explained — here's a clear, practical explanation.

What multi-point locking is

Multi-point locking engages the sash to the frame at several points along its length with one handle turn, rather than a single central catch — pulling it tight against the gaskets all around.

What to know

Look for this

  • Locks at several points at once
  • Pulls the sash tight against gaskets
  • Better sealing and security
  • Even compression around the sash
  • Operated by a single handle

Why it matters for your windows

Multi-point locking improves both security and sealing — it's a big part of why modern uPVC windows are airtight and hard to force. We fit it as standard where the style suits.
