There is a chimney like this:

I have ordered a hardened glass with four holes to be installed in front of chimney with dimensions like this:

There is a 2 cm empty space below glass to allow fresh air in.

I designed the dimensions in a way that the four glass holes would be between the bricks.

The problem is I'm not sure what's the best approach to attach the glass to wall through the holes. I prefer the glass to be easily removed and put back in place. Any idea is welcome.

The North-East glass hole is like this:

    I think you'll need to use a rubber eyelet. It'll protect the glass from the masonry screws and give a bit of space between the glass the brick. Just need to find the right size. – Micah Montoya Dec 19 '19 at 16:17

    Hardened glass isn't a thing. Are you using tempered glass or ceramic glass? I'd be worried about this shattering if you're using tempered glass. – user3757614 Dec 19 '19 at 16:48

    Be sure to allow for significant thermal expansion movement ; like large , soft rubber grommets. – blacksmith37 Dec 19 '19 at 16:51

    I don't like the sound of "security glass". That sounds like the kind with integrated layers of plastic, which would be bad for something placed in front of a fire. It might be a different type, but this is the kind of application where the technical properties of the glass matter. You really need to know the technology. – user3757614 Dec 19 '19 at 17:00

    Purely opinion, but I find this design aesthetically displeasing. Why not use a standard metal-framed fireplace glass door, or at least order a piece of glass which fits flush to the brick instead of in front of the brick? – Carl Witthoft Dec 19 '19 at 18:28

There is standard hardware for the job, from things like glass inserts in stair/deck railings and glass signage.

Try "glass standoff bolt" in a search engine. You'd put an anchor and stud (or screw, depending on the standoff design) into the masonry and attach that hardware to/with the stud/screw. Looks decent, easy to unscrew when needed.

  • The holes are around 8 mm in diameter. Do you think I'd have to use larger holes with glass standoff bolt? – user3405291 Dec 19 '19 at 17:41

    I guess it depends on standoff bolt design! – user3405291 Dec 19 '19 at 17:47
