Intumescent seals are a practical, well-established method of achieving Fire Resistance in designated Fire Resisting Doors. Heat from a fire causes the intumescent material to foam and swell, thus filling the gap between the door and frame and preventing the flow of hot gases and smoke. However, not all such seals are equal, and as concern over litigation grows, the thoughtful specifier must examine all the options to ensure that the seal chosen for each project really is the most appropriate. As the recognised leader in intumescent seal technology, Sealmaster offers products of proven performance and demonstrable cost-effectiveness, which can be specified with absolute confidence.

Strip sizes 10 x 4mm and 15 x 4mm are 30 minute rated and strip size 20 x 4mm is 60 minute rated. The 15mm width is the popular choice or doorset manufacturers who prefer the size due to its 'belts and braces' way of getting through fire tests. The leading brand fire resisting doors are fitted with the 15mm size, one strip for 30 minute doors and 2 strips running parallel, but approx 6mm apart, plus one brush and one plain where smoke seals are required around the door to achieve FD60 status. Additionally, factory doorset manufacturers use this size as it has enabled them to use one size cutter for either FD30 or FD60 doors, albeit set up differently. The Fire Only strip is plain, whereas the Fire & Smoke has a brush. All brushes are black with no frustrating plastic fin, reducing noise levels and resistance
