Sliding Window Grill: Inside or Outside?

Should a grill go inside or outside a sliding window? Here's an honest look at the trade-off.

The trade-off

An external grill deters entry before anyone reaches the glass, but it's exposed to weather and can look heavy. An internal grill is protected and less visible from outside, but the glass is reached first.

What to know

Look for this

  • External — deters before the glass
  • External — exposed to weather
  • Internal — protected, less visible
  • Internal — glass reached first
  • Inbuilt grills integrate with the frame

The practical takeaway

For a sliding window, an inbuilt grill within the frame often gives the neatest answer — security integrated with the window rather than bolted around it. We can build it that way.

Questions

Frequently asked

Should a window grill go inside or outside?

External grills deter entry before anyone reaches the glass but are weather-exposed and can look heavy. Internal grills are protected and less visible but the glass is reached first. Inbuilt grills within the frame often give the neatest answer.

Can grills be built into uPVC windows?

Yes — inbuilt grills integrate with the frame rather than being bolted around it, which usually looks and works better.

Do grills affect the window's operation?

Properly integrated ones don't — we design the grill around the opening style.
