Insulated soffit liner
RCM Caltech is an adhesively bonded soffit liner combining a non-combustible calcium silicate board (Siltech or Multipurpose), typically 6mm thick, with an insulation medium of either mineral wool, EPS or phenolic.
Caltech is primarily used in soffit liner applications 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 what we believe is the most extensive range of combinations available, all bonded with an ultra high-performance external grade adhesive.
- Long term durable bond
- Impact resistant boards from 3.2mm up to 12mm
- Extensive range of options
- 4 insulation mediums available
- Integrates with other RCM products
