My sister asked me to create radiator covers for her sunroom. And I was so happy to do it because hers needed a major upgrade. If you check out the before photos, you’ll understand why (no shade!). They were rusted old iron covers that were holding on for dear life. Let’s fix that!


Before you read any further, please check with local guidelines regarding the distance your materials need to be from your radiator. A general rule of thumb, is that plywood can withstand temperatures up to 200 degrees Fahrenheit. Always remember to conduct your own research.
I was able to create this with one sheet of lumber, high heat paint, nails and screws. It was super simple and cost less than $100!
I ripped down (cut) a sheet of plywood (4′ x 8′) using my table saw. In hindsight, it would have been worth buying a KregJig Rip Cut which I now swear by in order to cut large sheets of wood.

The radiator top is about 4″ in depth and the top piece hung over each side about 3/4″ in order to accommodate for the sides.

I cut the front of the top panel and sides (the front and top) at a 45 degree angle it would created a mitered edge when I put it together.
Building tip: To figure out how to set your table saw, measure the width of your plywood. Let’s say the width is 4″. The thickness is 3/4″. Subtract 3/4″ from 4″ and set your table saw guide to 3 1/4″ and your blade to a 45 degree angle. Doing this will ensure the table saw will only remove the necessary amount of wood without cutting away from your desired width.


Now you’ll create a front edge using the same above concept about mitering the edges.


It should start to look like this. You’ll need to created your top and bottom panels. Only the top panel will receive a mitered edge towards the top.
You can fill any spaces with wood filler. Cover your nails holes with nail filler as well.

With the frame complete, cut your horizontal slats. I cut my horizontal slats at a 2″ thickness. I glued and brad nailed it all into place like above. You can also use pocket hole screws but for this design, I didn’t think it would be necessary as these covers were not going to be touched. Don’t forget to use wood filler after this step too!
Make sure to sand if you want a smooth finish before painting.
And this is what the final product looks like.

This was one of my first ten builds EVER. Are there some areas that could be improved? Sure..but we get better in time. And I’m really proud of this. So this is your reminder –> don’t be afraid to get started. Just make sure to have fun in the process.
