Astroflame Intumescent Duct Sleeve
The Astroflame intumescent duct sleeves are simple to fit and cost effective (one sleeve can replace two collars). The sleeve can be fitted from one side and requires no additional mastic or specialist tools. Upon contact with the high temperatures present in a fire, the intumescent material will expand to seal the penetration, effectively blocking the smoke and flames from passing through.
