Dry lining
This particular cladding technique is achieved by placing pre-cut boards directly on top of interior walls and ceilings. Because surfaces like masonry, timber and brick will not give a smooth finish unless plastered used a sand and cement based render, dry lining offers a fast and practical alternative to having to wait for wet plaster to dry.
The plaster boards used for dry lining are usually mass produced, and can be made from a variety of materials and supplied in various lengths, widths and thicknesses.
Dry lining is much quicker than traditional plastering, but still creates a wall that is easy to paint or cover. By adding dabs of a plaster and adhesive mix to the wall, a dry lining specialist can press the plasterboard to ensure a secure bond is formed. This method quickly produces a smooth surface, saving both time and money.
To ensure that the insulating properties of the wall are not lost, specialist insulation can be glued to the back of the plasterboard to help keep the heat in and the cold out. When the plasterboard is being attached to metal or timber studs, the insulating layer can be fitted into the gaps between the stud work.

Suspended Ceilings
These can be defined as ceilings which are fixed to a framework suspended from main structure thus forming a void between the two components. The basic functional requirements of suspended ceilings are:
-
They should be easy to construct, repair, maintain and clean.
-
So designed that an adequate means of access is provided to the void space for the maintenance of the suspension system, concealed services and/or light fittings.
-
Provide any required sound and/or thermal insulation.
-
Provide any required acoustic control in terms of absorption and reverberation.
-
Provide if required structural fire protection to structural steel beams supporting a concrete floor.
-
Conform with the minimum requirements set out in the Building regulations and in particular the regulations governing the restriction of spread of flame over surfaces of ceilings and the exceptions permitting the use of certain plastic materials.
-
Design to be based on a planning module preferably a dimensional coordinated system with a first preference module of 300mm.
