Linear joint seals are passive fire protection systems designed to maintain the required building fire resistance across a separating element, plus, if and where relevant, to accommodate a defined degree of movement. Linear joint seals can be found in walls, floors, and in so-called head-of-wall applications – joints between walls and ceilings or walls and floors.
Linear Joints for the UK and Europe are typically tested to the BS EN1366-4 fire-resistance test standard.
