To lessen the chance of dirt marks from a radiator getting on to the wall immediately above it. Fit a blockboard shelf to the wall’, making sure that the shelf is wide enough to overlap the radiator by about 50 mm 2 in and long enough to extend about 100 mm 4 in at each end. The shelf can either be fixed into position with mirror plates, or on angle brackets concealed behind the radiator.
For complete effectiveness, glue a strip of foam draught excluder to the back of the shelf before fixing it to the wall. Force the shelf back so that the draught excluder is squeezed up tightly.
