Rmax ThermaBase-CI™
Continuous Insulation for Exterior Walls

This superior thermal insulation board is a composite product  manufactured with Rmax Thermasheath®-3 or Rmax Durasheath®-3 as the insulation layer bonded to a nailing surface. The standard nailing surface for ThermaBase-CI is 7/16” OSB (APA rated). Alternate nailing surfaces, such as 5/8” or 3/4” OSB or CDX plywood, are available upon request.    

ThermaBase-CI™ is engineered to allow for normal expansion of the wood without gaping the insulation layer.
