The Sealmaster IF60 intumescent fire door seal is a perfect method of achieving fire resistance in designated fire doors. The IF60 provides 60 minute fire protection and is suitable for single and double leaf, single and double acting fire doors where no smoke control is required.
This fire seal is rebated into the head and jambs of the door frame, and is aligned with the centre of the door edge. The IF60 intumescent fire door seal is interrupted at the hinges and lock/latch plate positions, but can be protected by Sealmaster Intumescent Plugs if required. It is also used in conjunction with IMP seals at the meeting stiles on double doors.
The heat-treated aluminium holder is easy to install, and retains the intumescent material securely and is correctly positioned in the rebate but without weakening either the frame or the door. Robust and durable in use, it offers excellent vandal and damage-resistance, plus good heat conductivity to assist early intumescence. It is recommended that the groove is routed to give a ‘light press fit’ for the extrusion. The seal should finish flush with the timber. Strips should be pinned every 200mm.
The intumescent fire seal is extruded from aluminium alloy and contains two reservoirs, each having substantial reserves of Sealmaster intumescent material. Sealmaster’s specially-formulated intumescent material is based on mono-ammonium phosphate, and is compounded to resist degradation by moisture or carbon dioxide. When triggered by heat it produces a low pressure, high volume foam that fills the gap between the door and the frame. As the foam remains soft during the period of intumescent action, it has the ability to re-seal the gap, should the door warp or be moved for any reason.
IF60 intumescent fire seal has been tested by TRADA. It was fitted to a 60 minute door assembly and achieved an integrity rating of 71 minutes. IF60 intumescent fire door seal has also been tested and approved by Certifire to conform to BS476 part 22.
Sealmaster IF60 fire door intumescent seal is supplied in standard lengths of 1050mm and 2100mm, but other non-standard lengths can be made available to order. Please call or email Firewise at +44 (0) 1223 839 727 or [email protected] for bespoke sizes, prices and availability.
