Compliance & What It Means

Not a fire seal. This product is not a fire-rated seal. It is designed for finishing and sealing raised or uneven door sills; it is a threshold/nosing profile rather than a fire-tested sealing product. If your door is a fire door, pair it with (or choose) a Kilargo intumescent fire seal tested to AS 1530.4.Ordering & dispatch.
