Mayplas Masonry Cavity Stop Sock (MP552) is designed to offer 60 minutes fire resistance between the outer brickwork and inner blockwork of masonry wall constructions. It can also be used for the control of sound flanking transmission at wall junctions.
- Vertical Stop Socks are compressed and friction fitted between the outer brickwork and inner blockwork - joints are close butted.
- Horizontal Stop Socks are compressed and friction fitted between the outer brickwork and inner blockwork - joints are close butted.
- MP552 is designed to be compressed by 15mm in the cavity as the brickwork is built up
- A DPC cavity tray with a minimum upstand of 100mm should be installed immediately above the stop sock (not when used as closer in external cavity wall at eaves level or at ceiling and roof junction)
