Recessed sensor in wooden windowframe

Postby seblbuk » Sat Nov 21, 2020 4:13 pm


I am about to have some new sash windows installed and need to install a sensor in each so we know if it's open (so the heating does not come on in the room).

The image attached shows the two sensors I have found, a surface mounted one (numbers 1&2, both are the same but 1 is pushed up so you can see the rim) and a flush one (numbers 3 & 4) that can also be recessed.

Where I would appreciate some advice is:

  • - Where the holes are drilled, should they be treated with anything before installing the sensor?
  • - If I use the surface mounted one, should I put anything over it to protect where the hole was drilled? or surround the sensor in something?

If I was to go for the flush one, would you suggest it is installed:

  • - Flush like number 3 (should I put anything over it to protect where the hole was drilled?)
  • - Recessed like number 4 with a filler (or something) over the top and painted?

Thank you for your help in advance.
