How To Make a Fireplace Screen Using a Window Sash

Now that Spring arrives in just 13 days ( I can see that smile on your face), I knew it was time to do something about hiding my soon to be unused fireplace box.    I to make a fireplace screen that could easily be moved away when the fire is burning and put back in front of it to hide it when not in use – it does not look pretty when there is not a homey fire lit in it.

As you know I have been trying to de-clutter and get rid of all the “stuff” that is just junking up my life.    When I was cleaning out one section of my basement, I came across this window sash.



I had totally forgotten about it. I have hung onto it for a very long time and am glad I did as I knew I could finally put it to good use.   I found it in curbside trash about 15 years ago and my Dad who loves to work with wood cleaned it up for me.  And then it sat, until last week.  I took it upstairs to see if it would fit in front of the fireplace box and it did. How exciting!!! Off to Lowe’s I went all excited with a plan in my head and to buy some wood shelf brackets.

Materials Needed:

Window Sash
4 wood shelf brackets
4  1 1/2” long wood screws
Paint and paintbrush
Krylon Looking Glass Mirror Like Spray Paint


Here are the 4 wood shelf brackets at I bought at Lowe’s. I think they were about $3.75 a piece. They have a decorative groove in them that actually matches the mullions on the sash. How cool is that ?  It was meant to be!!!


The hardest part of this project –  was that I had to flip the built in hook thingy in each bracket.  This was easy with my power screwdriver.  I just removed the screws, flipped it so the larger open section on the hook was at what I was going to use as the bottom of each bracket and screwed it back in.


On the window sash- I screwed in a screw 1/4-inch from the bottom on each side (back and front).  I left about 1/4” of the screw extended from the wood so the hook on the bracket could slide into it.   I used 1- 1/2 inch screws, but your sash may be a different thickness. You just want to make sure your screw is not too long that it goes through the other side of the sash.


When the screw is screwed into the sash the top part of it slides in the wide section on the metal hook.


Like this – the screw will be in the wood, but I wanted to give you an idea of how the brackets hook onto the screws.


Line up the bracket with the screw and push down until the bracket extends about an inch from the bottom.   It should be a very tight fit. If it moves you may have to adjust the screw into the wood deeper or extend more on the window sash.


There was one bracket that I could not get to stay in place and I used Liquid Nails to make sure it would stay.


Here is what I got –now it is ready for paint and a mirror finish.


For a subtle way to not be able to see through the glass panes I used Krylon Looking Glass Mirror Like Spray Paint on the back side of the sash.

This stuff is expensive.  It only comes in a small can and is $12.00 at Michaels. It is not sold in the same section with other paints, but with the bridal craft stuff.   You have to make sure the glass surface is very clean and then shake the can  for 2 minutes.  After every minute of use –you need to shake again. The directions say to use 5 light coats. I used about 10 and I would have added more , but I ran out of paint.

This photo is of the backside of the sash.  You can see it has a mirror like finish, but it is not shiny and looks a little pitted. It kind of looks a bit old – which is ok, but I think I may scrape it off from one of the panes and try it again to see if I get better coverage.  The cap on the can is really shiny and is a bit misleading. It does state on the back that it produces a dull finish.

Viewing the finish from the front of the sash does look better as it is under glass.



You can see it does have a mirror like quality as there is a subtle reflection that blocks from seeing inside the firebox. I only use this as a decorative screen to hide the dirty firebox when the fire is not in use – not as a protective screen when the fire is lit.


Now all my room needs is some Springtime touches in the way of flowers.

Hurry Spring!!!

    Dear Diane,

    You’ve done it again! I love the way you figure things out and break them down so they look do-able, logical and not too hard, just figuring it out and going step by step – all with economy and great style. I wonder what wallpaper or marbelized paper would look like in the panes of glass, or even fabric?

      Hi Kendra –

      I do not use it in front of a burning fire. I use it to hide the dirty flreplace when not in use. I remove it and place it behind a chair in the room, when the fire is lit. It is purely a decorative way to hide the firebox opening when the fire is not on. . I will add this to the post so others realize this, too. Thanks

    I’m so glad I found your decorating blog, because I just LOVE it! The idea for the window pane as a fireplace screen is nothing short of brillant!!! I have 3 old ones that I couldn’t toss, now I know what I will be doing with one of them. Now, that only leaves two remaining, but don’t feel pressured! Lol. Best Wishes, Catherine

    I have a question. How do you line up the screws so that the one in the front does not meet the one screwed into the back?I love this idea and ahve all rhe materials but am confused over the screw placements. Thank you. Marie

      Hi Marie – If your sash is not thick enough, use shorter screws. You want the screws long enough so they are secure. They also don’t get screwed in all the way – the head should stick out a bit to catch the wood braces that hold the sash up.

    Hi Diane, One more question. My window is 1 1/4 inches wide. The screw is 1 1/2 inch. I will leave 1/4 inch out for the brace. But if I put screws in front and back, even shorter ones, I don’t understand how they will not hit each other inside the sash if both are screwed in 1/4 inch up from the bottom on both sides. Did you put one screw higher and adjust the brace when you put it on? Sorry for the questions! Thank you. Marie

    Hi Diane, I bought shorter screws and it worked perfectly!Thank you for your help. I am going to put stained glas film on the backside of the windows. Thanks again. Marie
