Atlas Rboard® rigid insulation is a closed cell polyisocyanurate (polyiso) foam core, faced with a non-reflective coated glass-mat facer on both sides. Rboard® combines high R-value, enhanced durability from two coated glass-mat facers,and water resistive attributes in a high performance rigid insulation board.

Rboard® is suitable for a variety of continuous insulation (CI) applications. Panel sizes are 4' by 8' or 4' by 9'. Panels can be supplied in nominal 16" or 24" widths for use in cavity wall applications. Custom sizes are also available.


Recommended Applications:

Rboard® is a very versatile rigid insulation board for use in multiple energy saving applications. It is designed for all types of construction including commercial, institutional and residential. The coated glass-mat facers enhance the board’s durability in a similar manner to their use on exterior glass-mat gypsum boards. The coated glass-mat facers are more permeable than foil facers.

Common applications include:
  • Exterior and interior insulating sheathing for walls framed with wood or steel studs. Interior application requires a thermal barrier
  • Exterior or interior CI (continuous insulation) for cmu/block/concrete wall systems. Interior application requires a thermal barrier
  • Exterior CI (continuous insulation) for installation over wood or gypsum sheathings
  • Use over existing cladding to improve energy efficiency and provide a level surface prior to installing a new cladding
