RCM Caltech™ is an insulated soft liner panel which consists of a combination of either our Siltech calcium silicate board or our Multipurpose Cellulose fibre cement building board with a choice of insulation mediums bonded together.
RCM Caltech is primarily used in soffit liner application to bring un-insulated floor structures up to the current building regulations thermal requirements. Available with a choice of boards in a wide range of thicknesses, RCM Caltech offers we believe the most extensive range of combinations available, all bonded with a ultrahigh performance external grade adhesive.
- Extensive range of combinations available
- Impact resistant boards from 3.2mm up to 12mm
- 4 insulation mediums available in range of thicknesses
- Long term durable bond
RCM Caltech can be drilled, screwed and nailed with conventional hand tools. For cutting the product in any volume, we recommend the use of a RCM Poly crystaline diamond (PCD) blade with flat teeth configuration, to avoid excessive wear on unsuitable blades.
