List of featured suppliers of FLUES Twin-Wall Construction Four Hour Fire Rating on Building Products Index

In the event of a fire, the insulation will help to keep the outer layer of the flue cool, preventing damage to surrounding materials, while the inner layer will contain the smoke and fire. This type of construction is often required in commercial and industrial buildings where fire safety is of utmost importance.
