Ducts

New Project (44).png

APPLICATION OVERVIEW

In accordance with Building regulations, when ductwork passes through any element of construction which has a designated period of fire resistance, the integrity of that compartment should be maintained.

Our Rock Mineral Wool fire protection solutions are  designed to protect vertical and horizontal, rectangular and square steel ductwork associated with ventilation and/or air conditioning systems, in addition to ducted supply and extract systems (whether through ducts or plenums), mechanically assisted systems and those relying on
natural convection.

Why Mineral Wool?

  • Our Rock Mineral Wool solutions are non-combustible with a melting point in excess of 1000°C, providing up to 2 hours fire protection to steel ductwork.

  • Our solutions are applied in a single thickness, removing the need for multi-layer applications, and providing assurance of a uniform thickness and allowing for easy verification of correct installation on site.
