Whichever system is employed, some knowledge
is required of where certain fixtures are going so that extra
reinforcement can be added to allow heavy items such as kitchen
cupboards or bathroom basins
to be properly supported.
Electrical wiring and plumbing pipe work will also be run
through the wall during its construction and it is essential that
everything will be in the right place when the room is finished as
correcting even the smallest mistake afterwards, such as adding an
extra light switch, is time consuming. Large mistakes can involve
having to take down entire sections of plasterboard - a messy
process if the board has already been plastered.
When building a stud wall that will be used as the
wall of a shower cubicle special waterproof board should be used.
Aquapanel is a glass mesh reinforced, cement based board that can
withstand being immersed continually in water and therefore avoids
the problem of having to rip down tiles to replace plasterboard
should the shower develop a leak.
Wooden Stud Partitions
The most common type of internal wall is the
wooden stud-partition. Here lengths of 3"x2" or 4"x2" (75x50mm or
100x50mm) are made into a frame which runs across floor, walls and
ceiling. Studs are then attached between head (ceiling) and sill
(floor) plates at regular intervals and noggins skew-nailed between
them to stiffen them. Doorways are allowed for with cut outs in the
sill plate and extra studs above the door. Extra noggins or sheets
of wood can be attached between studs to allow for heavy
fixtures.
Metal Stud Partitions
The metal stud construction system uses the same
basic idea as wood, but the material is plated steel sheet extruded
into lengths of a C-profile shape which can be screwed together with
self-tapping screws. It is available in lengths of 2.4m to 4.2m (8'
to 14') and widths of 48, 60, 70 and 146mm. Again a frame is made
around the walls, floor and ceiling and studs added, however there
are no noggins between the studs with this system. For fixing heavy
items special fixing channels are available. Once finished the
partition is plasterboarded using only drywall screws; nails cannot
be used.
Cellular Core Partitioning
Cellular core partitioning consists of two sheets
of plasterboard with a honeycombed cardboard core, effectively
forming an entire wall section in one part. As before an outline
wooden frame of 2" PAR is created with locating blocks added where
the edge of the partition meets the frame. The cellular core sheets
are then slotted into place and screwed or nailed to fix them. Where
partition sheets meet at a corner or T-joint, extra battening needs
to be inserted into the sheets to allow a solid fixing between
them. |
