Though Rockwool FirePro gives effective thermal insulation for square and rectangular-shaped ductwork, that is not just what they are known for. These specially made duct boards give exceptional fire resistance and also superior sound insulation. Here are some very important features of this excellent product by Rockwool:

Make: Rockwool duct insulation board is made with non-combustible, high-density mineral wool with high-emissivity black foil facings on the front. Mineral wool does not only reduce heat loss in ducts but also helps give fire resistance for up to 2 hours, especially in ventilation and smoke extract ducts. 

Easy to Install: FirePro duct boards are easy to install. It is easy to cut using a  hand saw or circular/table saw. These duct insulation boards can be mechanically secured around the rectangular and square ductwork using insulation stick pins with washers or Fire-Pro adhesives. 

Fire Resistance: Rockwool duct board can safeguard ducting for up to two hours in addition to providing fire resistance when it passes through fire-rated walls and floors. This ensures that a fire cannot spread unnoticed throughout a building's ductwork. It is typically employed in commercial and industrial settings.

Thermal And Acoustic Insulation: Mineral wool insulation has low thermal conductivity, which helps protect ducts from heat loss. Stone wool also has the ability to use trapped air to increase its thermal efficiency. Also, due to their high density, these duct boards also soundproof ductwork. They help make the workplace more productive, by reducing the operational sound of ducts.
