Hi, I just had to make three radiator covers for our home. Didn’t really want to restrict air flow but my wife is starting a day care here and to get certified, they want the radiators covered. I built them with poplar and screening.

We have one upstairs the previous owners put in and I noticed under the top there is a 3/4” piece of insulation board under the top. Anyone heard of this or seen it done? I’m thinking maybe it’s too keep the top from getting too hot. Otherwise I can’t really figure out what it is for and if I should add it to mine.

Thoughts on what it does or if it should be there?

It’s to keep the top from warping. If it gets really hot on the bottom and not the top, it’ll turn into a pretzel.

+1 on what charlie said. I had to replace all of the covers in my house because the tops were cracked. In addition, you’l probably notice all of your radiators are under windows. Since heat rises, it makes sense to insulate the top as much as possible to try and deflect the heat into the room instead of right out the window.

Thankfully, we have pretty good windows. Now I just need to figure out how to lift my covers up by about 3/4” so I can put that insulation is :) Maybe some little decorative legs . .

Have your say...
