Linings (Plywood & Sawn Timber) Print E-mail
An attractive and practical method of lining one or more walls in a room is to use timber in either sheet form (such as plywood) or in the form of specially profiled boards.

Plywood sheeting used for lining a wall sometimes has a surface which is smooth and sometimes has a surface which has been decoratively grooved.

The specially profiled boards are generally referred to as lining boards.

The boards are profiled to overlap and may be fixed horizontally, vertically or at an angle.

There are a number of profiles produced. The various profiles offer a range of visual impacts. Profile descriptions include V-jointed, Double V-jointed, and Shadowline.

Lining boards are a specialty timber product. Specialty timber products (sometimes referred to as milled products) include products that may have either a sawn or dressed surface and are graded primarily for appearance although some do have a strength requirement. They include flooring, cladding, lining boards, joinery products and domestic decking. There are several grades described in Australian Standards and a range of standard sizes and profiles available. See: Timber & Wood Products - Sawn or Milled Timber.

Sometimes lining boards do not live up to user expectations. In most cases this is not the fault of the material but rather as a result of a lack of understanding of the various species of timber, their suitability and their installation and maintenance.

Any timber (treated or untreated) that is used for decorative purposes in a home, may from time to time be subjected to moderate changes in the "environment" within the home. These changes can result from the normal seasonal changes and from the application of mechanical heating and cooling. When subjected to such changes, the timber may take up and lose moisture from or to the atmosphere as the environment around the timber changes. The timber will expand or contract when it takes up or loses moisture. Although the expansion and contraction will normally be almost negligible, the profile and the method of fixing of lining boards allow for any expansion in the width of the lining boards during periods of higher humidity.

The application of a protective coating to the timber surface is recommended. Protective coatings include products which penetrate the surface of the timber and products which provide a film or coating to the surface of the timber.
