Timber Frame Cavity Barrier MP551

Designed to offer 60 minutes fire resistance between the outer brickwork and inner timber sheathing of timber frame constructions - can also be used for the control of sound flanking transmission at wall junctions

Meets the requirements of:-

  • 2000 Approved Document B Fire Safety
  • 2003 Approved Document E Sound Resistance
  • Robust Details Part E
  • NHBC Standards 2005

Manufactured using polythene enclosed non combustible rockfibre in bespoke sizes designed to be compressed by 15mm within the cavity - this “made to measure” cavity barrier design provides a minimum of 1 hour fire resistance and is crucial in sound applications where “flanking transmission” can be the weak link of an otherwise robust construction

The MP551 Standard Range has been tested by Warrington Fire Research (WFRC No: C83002) to provide 1 hour fire resistance - double the minimum requirement - meets Part B and Part E (incl Robust Details) of The Building Regulations 2000

Fitting Mayplas 551 Timber Frame Cavity Barriers


Vertical Barriers are stapled (at 150mm centres) to the inner timber sheathing by both flanges - joints are close butted. 551 is designed to be compressed in the cavity by 15mm as the brickwork is built up Horizontal Barriers are stapled (at 150mm centres) to the inner timber sheathing by the upper flange only - joints are close butted.

Cavity Barrier is designed to be compressed by 15mm in the cavity as the brickwork is built up

Meeting the Sound Flanking Transmission Guidance given in 2003 Approved Document E for Timber Frame Constructions


In timber frame constructions Mayplas 551 Timber Frame Cavity Barrier is the ideal solution for the control of sound flanking transmission and can be used in all wall and floor junctions detailed in Approved Document E where cavity stop or flexible closer are mentioned Mayplas 551 Timber Frame Cavity Barrier meets the requirements of Robust Details Part E in constructions where “close cavity with flexible cavity stop” is specified

Standard range 1 hour fire resistance which exceeds requirements of 2000 Approved Document B
