Explain this equation
Gives the lining channels, brackets, track and track fixings for a GypLyner metal-framed wall lining.
N1 counts GL1 lining channels at centres s along wall length L. Each channel needs brackets at vertical centres sb over height H, giving Nb. Lt is GL8 track at floor and ceiling. Nf counts fixings for both tracks at centres sf.
The 1000 converts metres to millimetres. Rounding up with +1 gives a channel at each end of the wall; rounding up the brackets keeps every bay at or under the maximum spacing between the track ends.
Sense check: a 4.8 m wall at 600 mm centres takes 9 channels; at 2.4 m high with brackets at 800 mm that is 3 brackets each, 27 in total.
Watch out: close the bracket centres where the lining will be tiled, and add channels at openings and corners.

Good to know
GypLyner walls use GL1 lining channels at 600 mm centres held in GL8 track at floor and ceiling, with GL2 (or GL9) brackets fixed to the wall at 800 mm vertical centres (closer where the lining will be tiled). Track is fixed at 600 mm centres. The count assumes each channel has bays of no more than the bracket spacing between its ends in the track. Add channels at openings and internal and external corners.
Common mistake
Spacing brackets to suit the background fixings rather than the 800 mm maximum, or forgetting the extra channels round windows and doors.
Limits
Straight wall, no openings. Brackets and anchors must suit the background; boards, screws and insulation are counted separately.
