Thermafiber Rainbarrier Ci High Compressive Insulation

Thermafiber® RainBarrier ® ci High Compressive (80) continuous insulation boards are designed to support cladding attachment with minimal penetrations. The use of ThermaCrimp™ technology allows for excellent compressive  strength while providing thermal efficiency, non-combustibility, water repellency, and flexibility when working with uneven substrates. RainBarrier ® ci High Compressive (80) can be used behind light weight cladding — including combustible and open-joint assemblies.

Features

  • High compressive strength to support cladding attachment system with minimal penetration through continuous insulation
  • More than 10% lighter in weight than the leading competitor’s product
  • Vapor permeable
  • Tolerant of substrate irregularities
  • Non-combustible and non-deteriorating
  • Fire resistant to temperatures above 2,000°F (1,093°C)
  • Enhances acoustical performance
  • Minimum 70% recycled content1
  • Contributes to credits in several green building programs such as LEED ® and Green Globes ®

Standards, Codes Compliance

  • ASTM C612, Mineral Fiber Block and Board Thermal Insulation, Types IA, IB, II, III, IVA, IVB
