Fire safety requirements play an increasingly important role in both new construction and renovation work. Decisive for fire development is the degree to which fire and smoke develop and the degree of fire penetration from, for example, the façade inwards.
Fire resistant crack seals are a decisive factor to prevent fire spreading as a result of fire penetration from the facade as much as possible. To limit fire propagation, HARDCAST® is a high-quality fire retardant butyl tape. The butyl tape has fire class B and makes it possible to realise an airtight and fire-safe detailing around window frames.
European established tests determine how products react to heat and the extent to which they contribute to a rapid spread of a fire. The fire retardant butyl tape FSR 40, manufacturerd by CARLISLE® Construction Materials B.V, did not show flashover in any of the tests and made a very limited contribution to the fire.
In addition to flammability (fire class), the classification for smoke development and drop formation is also determined. Burning droplets are a direct danger to people (for example rescuers) and to the creation of new fires in other places.
A distinction is made between different classes where HARDCAST FSR 40 achieves the highest classification in terms of drop formation and in the field of smoke formation. Low smoke production and no production of droplet formation as a result of burning parts.
