Mannok IsoFrame – PIR insulation for Steel/Timber Frame
Foil faced rigid Polyisocyanurate (PIR) insulation, for external cavity walls of conventional timber and steel framed dwellings with a masonry outer leaf. Height restrictions apply in some cases. Mannok IsoFrame may be installed between structural studs. Also, used with insulated dry lining systems and as insulated sheathing or used as part of a system incorporating any combination of these options.
Mannok IsoFrame has been tested to BS EN 1365-1:2012 and BS 476-21:1987 for use with structural steel/timber studs, where a fire resistance of 30 minutes is required. In steel stud construction it has 60 minutes fire resistance.
