Laying a board over a radiator

Putting a marble board or tablet over a radiator brings several advantages: it can serve as a shelf, it partially hides the radiator which is rarely a beautiful object, and especially it prevents heat from mounting against the wall, thus delaying the clogging of wall coverings, be they paints, wallpapers or fabrics.

Necessary material

  • Screwdriver
  • Drill (with depth guide)
  • Anchors
  • Screw
  • Silicone glue
  • Mounting bracket
  • Metal brackets

Steps

  1. Use mounting brackets
  2. Make a pose on squares

Use mounting brackets

1. In the case of traditional and sufficiently large radiators, the use of mounting brackets remains the simplest solution. These adapt to the rounded part of the radiator located between the elements, the fixing is done by a collar with springs.
In addition, these supports are easy to disassemble, for example during a subsequent painting of the radiator, they are also compatible with several types of radiators.
They are equipped with a sliding tab for fixing the marble plate. The tab is adjustable with a locking screw, which is tightened with a screwdriver.

Iron radiators require different supports.

2. The method also applies to newer steel radiators. Due to the narrowness of these radiators, the shape of the mounting bracket differs. The flush collar gives way to a long rod that rests on the inside of the radiator. It is then necessary to tighten the fixing screw to lock the support in the intended position.
As in the case of the previous assembly, the supports, which have a thickness of a few centimeters, leave a gap between the radiator and the marble plate.

The bracket must be adjusted before screwing.

3. Then adjust the bracket to the desired width and tighten the screw tightly. Ideally, the marble slab should extend a few centimeters beyond the edge of the radiator.

Make a pose on squares

The plate can be fixed to brackets by gluing.

4. A radiator shelf may also be installed on two brackets, of the type used for the installation of wall shelves.
It is then necessary to glue the part of the square on which the marble plate must rest, after having screwed the other branch against the wall using pegged holes.
It is necessary to choose a silicone-type adhesive capable of withstanding the important temperature variations that are inevitable in this configuration.

5. You can also screw the marble plate on the square. This technique provides superior strength to the tablet, but the relative fragility of the stone implies the respect of some precautions.
To make holes in the marble, start by placing the plate between the jaws of a vise. Once you have located the holes, drill with an electric drill equipped with a tungsten carbide drill. Also carry a depth guide so that you do not cross the plate during drilling.

6. The holes thus made can then be pegged, and the square screwed firmly on the shelf. The other advantage of choosing a square is to be able to place the plate sufficiently high, 10 cm on average, above the radiator.
