Fermacell 1H37 Insulated Timber Stud Partition

Fire resistance:

60 minutes.

Stud centres:

500 mm.

Insulation (minimum density):

2 x 60 mm mineral wool: 10–60 kg/m³ density.

Linings:

Two layers of 10 mm Fermacell each side.

Recycled content:

Best Fermacell gypsum fibreboard contains 100% recycled content. All by-products recyclable.

Other requirements:

Fire stopping around service penetrations. Frame out openings with the same number of layers of board as per above specification. Sockets backed using baffle boxes, intumescent putty pads or suitable rock mineral wool, sufficient to maintain the fire/acoustic performance.
