Knauf SHAFTLINER MOULDSTOP User manual

Step 2: Install first SHAFTLINER MOULDSTOP panel
■To enable fixing of aluminium clip, cut the first SHAFTLINER MOULDSTOP panel to width so that its edge falls
not less than 50mm from timber stud.
■Fit SHAFTLINER MOULDSTOP panel fully down into the PARTIWALL base track and align with end of track.
■Fit PARTIWALL end track tightly over SHAFTLINER MOULDSTOP panel and into the base track. Screw fix
end and base track junction with 10g x 16mm Type ‘D’ drill point wafer head screws.
■Fix PARTIWALL end track to timber frame with PARTIWALL aluminium clip.
Step 4: Continue installing SHAFTLINER MOULDSTOP panels and PARTIWALL studs
■Continue to install SHAFTLINER MOULDSTOP panels and PARTIWALL studs until reaching end of wall.
■As framing progresses, fix PARTIWALL studs to timber framing with PARTIWALL aluminium clips.
■Cut the last SHAFTLINER MOULDSTOP panel in line with the end of PARTIWALL base track. Fit PARTIWALL
end track tightly over the edge of the panel and screw fix end and base tracks junction with 10g x 16mm
drill point wafer head screws both sides.
■Fix end track to timber frame with PARTIWALL aluminium clip.
Step 3: Install first PARTIWALL stud and clip
■Fit PARTIWALL stud fully down into the PARTIWALL base track and move tight over the edge of SHAFTLINER
MOULDSTOP panel. Tap lightly to give a snug fit.
■Fit second SHAFTLINER MOULDSTOP panel into PARTIWALL base track and push tight into the PARTIWALL stud.
■Fix PARTIWALL stud to timber frame top plate with PARTIWALL aluminium clip.
Step 1: Install base track
■Use full track lengths, spaced 6mm apart.
■Position PARTIWALL track at min 20mm clearance along full length of the timber frame, starting and ending
in line with the timberl frame.
■Fix each track length to slab/foundation with approved concrete fasteners at 600mm maximum spacing and at 150mm
maximum both ends.
Installation Procedure (PWT60.1)
■Ensure that SHAFTLINER™ MOULDSTOP panels, PARTIWALL®studs and end tracks are the same length. Cut to length if required.
■In a multi-level SHAFTLINER MOULDSTOP Fire Barrier, PARTIWALL studs at upper levels are recommended to align with the studs below.
■PARTIWALL aluminium clips must be installed progressively as the SHAFTLINER MOULDSTOP Fire Barrier is erected.
■PARTIWALL aluminium clips must be spaced at maximum 600mm horizontally and 3000mm vertically.
■For aligned floors, PARTIWALL aluminium clips must be directly opposite on both sides of the PARTIWALL studs, unless noted otherwise.
■For offset floors, PARTIWALL aluminium clips can be staggered in line with floors on each side of the wall.
■Fix PARTIWALL aluminium clips to PARTIWALL studs with 2 x 10g x 16mm Type 'D' drill point wafer head screws (2 x 10g x 30mm Type 'D'
drill point wafer head screws if fixing through 16mm FIRESTOP®plasterboard).
■Fix PARTIWALL aluminium clip to timber frame with 2 x 6g x 25mm Type 'W' timber screws.
■SHAFTLINER MOULDSTOP Fire Barrier must be adequately braced against wind forces until the building is enclosed.
■When laminating 16mm FIRESTOP to Fire Barrier ensure butt joints fall centrally between PARTIWALL studs.

Step 6: At mid-floors
■Screw laminate 16mm FIRESTOP®to one side of SHAFTLINER™ MOULDSTOP Fire Barrier with 10g x 40mm
Type ‘L’ laminating screws at max 400mm centres (both directions) and nom 10mm from the edges. Ensure minimum
150mm overlap above floor and below ceiling level. Plasterboard joints do not need to be set with compounds.
Ensure joints are tight. Butt joints must fall centrally between PARTIWALL studs.
■Screw fix PARTIWALL aluminium clips through 16mm FIRESTOP into PARTIWALL studs and end tracks and
fix PARTIWALL aluminium clips to timber frame.
PARTIWALL STUDS ON UPPER
LEVELS MUST ALIGN WITH
STUDS BELOW.

Step 10: Seal for fire
■Install continuous Knauf Firepack®mineral fibre packer at external wall junctions and under roofing.
■Fill cavities between roof battens with compressed Knauf Firepack mineral fibre packer.
Step 9: At roof
■Measure and cut SHAFTLINER MOULDSTOP panels and PARTIWALL studs to pitch of roof.
■Allow 25mm gap at top of SHAFTLINER MOULDSTOP panels for frame shrinkage and roof movement in pitched
roof, flat metal roof, parapet and box gutter applications.
■Fix PARTIWALL track on rake and fix PARTIWALL studs to roof frame on one side with PARTIWALL aluminium clips.
■Screw fix top and end track junctions with 10g x 16mm Type 'D' drill point wafer head screws.
■Screw-laminate 16mm FIRESTOP to one side of SHAFTLINER MOULDSTOP with 10g x 40mm Type ‘L’ laminating
screws at 400mm max centres (both directions) and nom 10mm from edges. Ensure minimum 150mm overlap
below ceiling level. Plasterboard joints do not need to be set with compounds. Ensure joints are tight. Butt joints
must fall centrally between PARTIWALL studs.
■Ensure minimum 150mm overlap below ceiling level.
■Screw fix PARTIWALL aluminium clips through 16mm FIRESTOP into PARTIWALL studs and end tracks
and fix PARTIWALL aluminium clips to timber frame.
Step 8: Next level of SHAFTLINER MOULDSTOP Fire Barrier
■Using full track lengths, install PARTIWALL bottom track for the upper level of
SHAFTLINER MOULDSTOP Fire Barrier back-to-back with the top track below and
leaving 6mm gap between track lengths. Screw fix each track length with 10g x 16mm
Type 'D' drill point wafer head screws at 600mm maximum centres and at each end.
■Install SHAFTLINER MOULDSTOP panels, PARTIWALL studs and clips as per level
below. PARTIWALL studs must align with studs below. If PARTIWALL studs are
not aligned with studs below, fix back-to-back tracks at max 300mm centres.

■Apply continuous Firesound™ sealant along PARTIWALL®base track/floor junction on one side only.
Step 7: Install top track
■Using full track lengths, fit PARTIWALL top track over the installed SHAFTLINER
MOULDSTOP panels and PARTIWALL studs.
■Push top track fully down over the top of PARTIWALL studs.
■Screw fix top and end track junctions with 10g x 16mm Type ‘D’ drill point
