Description

Smoke Exhaust Duct Insulation Board is used when basement smoke exhaust ducts, fan room duct sections, and fire-control air routes need a protective insulation layer that can be installed without changing the main route. The product is checked around smoke duct board enclosure, size data, facing, and seam treatment. These points reduce wrong cutting and help the site team keep the layer neat after delivery.
