Abstract
Abstract Panels for cladding floors, walls and ceilings of rooms for locating ducting for carrying heating/cooling media for controlling the room temperature. Mounting panels are formed from thermally insulating foamed plastics material with projections of different diameter in rows and columns to locate flexible tubing thereon. The mounting panels have jigsaw-like edges to allow for interlocking. The projections are solid and flat structural panels typically of steel or aluminium and adapted to be screwed or glued to the protrusions. Location of the structural panels is assisted by annular rims on the underside thereof around the screw holes, which penetrate into the projections. Methods of moulding the mounting panels from foamed polystyrene are described and a preferred form of mould to give differential foaming. A fixing screw having particular relationships between thread and core dimensions is described for securing to foamed plastics materials and the like.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
129 words
A base panel for use in a surface facing system, said panels serving to support heating/cooling media ducting and to carry face plates covering said ducting, said base panel having a substantially planar face adapted to be secured to said surface and, on the opposite face thereof, a plurality of first projections and a plurality of second projections, each of said first and second projections being of generally cylindrical configuration with the diameter of said first projections being greater than the diameter of said second projections, said first and second projections each being located in uniformly spaced rows with rows of said first and second projections alternating, the free space between adjacent ones of said rows being of a width substantially equal to the external diameter of said ducting.
Claim 2
Dependent Claim
129 words
A base panel for use in a surface facing system, said panels serving to support heating/cooling media ducting and to carry face plates covering said ducting, said base panel having a substantially planar face adapted to be secured to said surface and, on the opposite face thereof, a plurality of first projections and a plurality of second projections, each of said first and second projections being of generally cylindrical configuration with the diameter of said first projections being greater than the diameter of said second projections, said first and second projections each being located in uniformly spaced rows with rows of said first and second projections alternating, the free space between adjacent ones of said rows being of a width substantially equal to the external diameter of said ducting.

Claim 11
Dependent Claim
27 words
The panel of claim 1 wherein a cavity is formed in the upper surface of at least some of the projections which cavity tapers towards its opening.
Claim 12
Dependent Claim
59 words
The panel of claim 1 wherein the dimensions of said base panel are such that the edges of said panel intersect the centers of lines of said first projections and in these edge faces alternate protuberances and complementary recesses are provided for fitting similar recesses and protuberances along the edge faces of adjoining panels, for fitting the panel together.
Claim 13
Dependent Claim
21 words
The panel of claim 11 wherein said protuberances and complementary recesses are provided in the intersected surfaces of said first projections.
Claim 14
Dependent Claim

The panel of claim 12 wherein one protuberance and one complementary recess are formed in the intersected surface of each projection, both at an equal distance from the center of the circle of which the projection forms a part, and also equidistant from the perpendicular edges of the intersected surface of the projection.
Claim 15
Dependent Claim
50 words
The panel of claim 13 wherein a projection which is situated at a corner of the mounting panel and is intersected twice by the two perpendicular edges to form a right-angled quadrant, is formed with a protuberance on one cut surface and a complementary recess on the other cut surface.
Claim 16
Dependent Claim
14 words
