The firestop cord is the System’s most internal element. Its primary function is to act as a barrier against flames, smoke and hot or inflammable gases in the event of fire, stopping them spreading to the rest of the installation.

This is especially important if the joint lies between fire compartments, where fire regulations demand that such compartments are totally insulated and compartmented, confining fire and smoke inside. In these cases, any opening between compartments, such as structural joints, must be sealed and comply with the required degree of fire resistance.

Sealing with firestop cord will also be applicable to joins with curtain walls or the edges of framing, in firestop walls, in technical duct through-holes and any element that must be sealed to stop fire from spreading.

The firestop cord can be installed independently, though it is an important component and the perfect complement of the structural joint. It is always recommendable to install it alongside the other elements in the System, acting as a safety system that will protect the installation and occupants’ health.

Technical characteristics:

  • Composed of fireproof, non-biodegradable, mineral fibres, covered in a network of fibreglass hairs. Does not contain asbestos or give off toxic smoke in the event of fire.
  • Strongly resists the usual aggressive chemical agents and damp.
  • Possesses an operating temperature of 780ºC.
  • Has undergone trials in accordance with European standards, obtaining a fire resistance classification of M0 / A1 S1 (fireproof ) (EN 13501:2:2016), and fire resistance of 240 minutes (EN 1366-4).
  • It is available in several diameters to cover differing joint widths.
