Plastic polymer backed stone panel
Normally we make this type of stone panel in marble (travertine, limestone).
It is composed of 4mm marble (travertine, limestone) veneer + 3mm plastic polymer back, total 7mm thickness.
1200mm x 2400mm
About 3.70 pounds/SF (18Kg/m2), while 11.30 pounds/SF of 3/4" solid marble (travertine, limestone) slab (55Kg/m2).
It is only 1/3 weight of 3/4" solid marble (travertine,limestone) slab, So it is an ideal decoration material for high rise buildings to deduct weight load, it is also a good material for old building renovation such as hotel, school, hospital, bathroom etc.
Time and labor cost save:
Because this type of stone panel is very thin only about 7mm thickness, it is unnecessary to take off the old covering ceramics or tiles, what you need to do is just to cover it onto the old coverings directly,by this way, you can save a lot of time and labor cost.
