Rockwool Comfortboard 80 R5.0

Comfortboard 80 is a type of rigid insulation board used in building construction to improve energy efficiency and thermal performance. The board measures 4 feet by 8 feet and is 1 1/4 inches thick, providing an insulation value of R5.0.
R-value is a measure of thermal resistance, indicating how well a material resists heat transfer. The higher the R-value, the better the insulation performance. An R5.0 insulation value means that Comfortboard 80 can provide significant thermal resistance, helping to reduce heat loss or gain through walls, roofs, or floors.
The board is made of a rigid mineral wool material that is designed to be water-resistant, vapor-permeable, and fire-resistant. It is suitable for use in a variety of building applications, including exterior sheathing, interior walls, and ceilings.
Comfortboard 80 is often used in high-performance building projects to help meet energy codes and achieve green building certifications. It provides a durable, long-lasting insulation solution that can help improve energy efficiency, reduce heating and cooling costs, and enhance occupant comfort.
