Overview
About Fire-rated linear joint seals
Linear joint seals combine backing (often stone wool) with fire-rated sealants or sprays, sized for joint width and movement.
They are tested to EN 1366-4 (classified under EN 13501-2), UL 2079 / ASTM E1966 for joints and ASTM E2307 for perimeter fire barriers at curtain walls, and AS 1530.4.
Head-of-wall joints under steel decks need systems tested with the deck profile.
