To be applied to mineral fibre wool boards and used to help reinstate the fire resistance performance of wall constructions (where they have been provided with apertures for the penetration of single or multiple services).

Features and benefits:

  • For service penetration and blank seals.
  • Can be spray, brush or trowel applied.
  • Suitable for internal use without additional environmental protection according to ETAG 026-3.
  • Remains flexible between -5°C to 70°C.
  • Easy to use.
  • Fibre free coating.
  • Life expectancy of over 25 years.
  • CE marked.

Applications:

  • Flexible and rigid walls of 100 mm minimum thickness.
  • Large openings in walls with additional supports.
  • Suitable for use with composite panels and cross-laminated timber (CLT).

Approved by/ conforms to:

  • IET (IEE) 17th Edition Fire Stop Compliant to Regulation 527.1-3 – 'Electrical Installations'.
  • BS 7671-2008, chapters 42 and 52 – 'Electrical Installations Fire Resistance'.

Supplied in 2.5 kg, 5 kg, 10 kg, 20 kg and 25 kg pails.

Pyrocoustic® Sealant is required to seal all joints and junctions during the sealing process. PyroPro® HPE Sealant is required to seal around specific services. Can be used in conjunction with Stopseal® Batt products. Consult manufacturer to view performance data in different applications.
