Fermacell 1S11 H20 Insulated Partition

Fire resistance:

30 minutes.

Stud centres:

600 mm.

Linings:

One layer of 12.5 mm Fermacell Powerpanel H20 to each side.

- Fixings:

35 mm Powerpanel screws at 250 mm centres.

Joint treatment:

Fermacell Jointstik 1 mm glued joint.

N.B. For Powerpanel H2O - ALL joints must be fully supported / backed.

Insulation (minimum density):

60 mm mineral wool: 25 kg/m³.

Powerpanel H2O finishing:

Tiles:-

Powerpanel Surface Finish to Powerpanel H2O Boards. All joints must also be reinforced with an alkali resistant 70 mm Glass Fibre Mesh reinforcement Tape embedded into the Powerpanel surface finish.

N.B. Tiles must NOT be fixed over Powerpanel Surface Finish.

Other requirements:

All Powerpanel H2O joints must also be reinforced with an alkali resistant 70 mm Glass Fibre Mesh reinforcement Tape embedded into the Powerpanel surface finish.

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.

Movement joints are required at maximum 8 linear metre intervals.

Refer to manufacturer's literature. Vapour barrier as required for high humidity areas.

For tiled areas reduce studs to 400 mm centres as required. Tile adhesive to be suitable for cement based substrate.

Provide door reinforcement as required to suit door weights and opening size. Ensure no vertical joints at door jambs.

Offset all board joints by minimum 200 mm.

Metal studs:

• In Swimming Pool and other corrosive environments, the steel studs and associated components must have additional Corrosion Protection - e.g. C5 coating.

• 75 mm Fermacell DIN Standard Steel (50 mm fixing face, 0.6 mm gauge).

• 100 mm Fermacell DIN Standard Steel (50 mm fixing face, 0.6 mm gauge).
