Sealmaster N60. 60 min Fire & Smoke seal
N60 is a combined fire and smoke seal for 60 minute, single action, fire resisting doorsets.
The seal consists of an aluminium alloy extruded profile, having two reservoirs of Sealmaster intumescent material, and a self-extinguishing, flame-retardant, elastomeric blade.
In normal use, the elastomeric blade seals the gaps between the door and frame, and act as an efficient draught seal. The seal is interrupted at the hinges and lock/latch striker plate, and protection at these points is obtained with Sealmaster intumescent plugs.
When heat from the fire reaches the IF60 seal, the intumescent foams, swells and fills the gaps around the door 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.
N60 with flame-retardant elastomeric draught/smoke blade insert was tested by TRADA. Stability and intergrity were retained for 71 minutes. Copies of test reports are available on request. N60 fire smoke seals have been tested and approved by Certifire to conform to BS476 part 22. This is the most demanding 3rd party certification scheme in the industry.
