Steel Encasement Solutions
Steel encasement is commonly achieved using non-reactive materials such as boards or sprays, or reactive solutions such as intumescent coatings. Thin film intumescent coatings provide the most effective insulation through chemical reactions at high temperatures, resulting in the coating swelling and creating a low conductivity layer of protection. These coatings provide fire resistance for 30, 60, 90 and even 120 minutes.
Boards are used for structural fire protection to encapsulate structural steel components with minimal disruption and a clean, boxed appearance. Fire resistance of steel encasement solutions is measured according to fire tests described in BS 476-20 and BS EN 1363.
