Radiator Cover heat protection

[chipster]

Hi Guys,

I am instructed by the wife to make a radiator cover/cabinet.

I am to use 3/4" american oak and the outer dimensions of the cover are 1600 x 620 x 190.

I think the water in the radiator is approx 60 degrees.

Obviously the wood is going to dry some under these conditions when the radiator is used in the winter and the wood will probably increase its moisture in the summer when the radiator is not in use.

Can anyone recommend a finish that will fix the moisture content?

If thats not possible should I consider allowing the wood to move by means of some unfixed joints?

Cheers in advance

How about lining the inside with insulation? I've used the silver coated bubble wrap before now, albeit for man made board.

You'll be advised not to make it at all. Apparently they are very inefficient at letting the radiator do the job you pay it to (or pay for it to do).

I guess the whole idea of a radiator is to radiate heat. Defeating the object by covering it. I am going to make it anyway, its always to warm in that room so it will suit me if it doesnt work at all :lol:

I will be leaving a 3/4"gap all around for the air to circulate and the wood wont be in direct contact with the radiator. Gaps at the bottom to allow the air to flow past the radiator and through the top vents.

Any views on the finish? Oil?, varnish?

I think any oil based emulsion will be fine. Eggshell is my fav

For AWO???

I'd make it out of oak veneered MDF, with solid oak lippings. Finish with a laquer. Coloron do a brush on product which i've found to be quite good.

oh sorry, miles away. In which case i'd just use Osmo Poly X. Simples.

Actually, inspite of their name radiators give out most of their heat by convection. They use the chimney effect to circulate heat. What is needed in a radiator cover is a gap at the top and bottom the front has little impact. The gaps want to be at least the same area as the top of the radiator.

At least this is what I was taught 20 odd years ago when I did my apprenticeship and it has worked for me on many jobs I've designed.

Hope this helps
