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 & swell, thus filling the gap between the door & frame & preventing the flow of hot gases & smoke. However, not all such seals are equal, & 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 & demonstrable cost-effectiveness, which can be specified with absolute confidence.
