ROCKWOOL FIREPRO® DuctRock® Slab – per 1.2m length

Insulating ductwork can be beneficial for reducing thermal transmission as well as protecting the structure in the event of a fire which can amount to costly damages. ROCKWOOL FIREPRO® DuctRock® Slab can provide up to 2-hours’ fire protection to ductwork in addition to fire resistance where they pass through fire rated walls and floors. This provides assurance that fire cannot spread unseen through ducting around a building.
