Panel Installation and Maintenance

Correct installation of a veneered panel is fundamental to its performance so it is vital that care is taken when handling Shadbolt panels.

Veneered panels are normally supplied fully finished (finishing on site is not recommended) so they do not require any further treatment on site. Care is essential when handling on site to avoid damage to the veneers, as it may be difficult to obtain matching veneer for repair purposes.


Examples of typical fixing methods are shown below:

Timber battens
Horizontal timber battens are fixed to the background, and the panels fixed direct to them by woodscrews. Fixings would normally be at the panel joints; there are various joint details which can be used to conceal the fixings.
It is essential that battens are accurately fixed to provide a true vertical and level surface to the finished panelling.

Split battens
Split battens are fixed to the wall and to the back of the panels, which are then simply lifted into place.

Proprietary fixings (example)
Z Bar system : aluminium interlocking sections can be used in a similar way to split battens. One section is fixed to the wall and the other to the back of the panels, and the panels are lifted and hooked on.

For split battens and Z Bar system aluminium sections, panel heights must be at least 50mm less than the floor-to-ceiling height to allow them to be lifted over the fixings and dropped into position. These methods allow panels to be removed for access, repair or refurbishment.



It is the nature of the panels that the vertical joints between them will be visible. They may be treated as a feature, for example a recessed joint or jointing strip, or as simple butt joints.

Examples of some of the most common joint treatments and corner details are shown here, but Shadbolt are able to manufacture to any suitable details required.


It is essential that the following conditions are observed in order to avoid any adverse effects on panels and their finishes.

Panels must not be installed until the building envelope is complete and weathertight, all wet trades work is complete, and heating/air conditioning has been commissioned. Conditions should be as close as possible to those expected in the occupied building.

Temperature should be in the range 13oC to 21oC (55oF to 70oF). Relative humidity should be conducive to an optimal product moisture content within the range 10% to 12% during storage, installation and thereafter. After installation, panels should not be subjected to sudden or extreme changes in temperature or humidity. Please see the moisture content graph opposite.

If it is unavoidable that heating or air conditioning is brought into operation after installation, this should be done gradually over as long a period as possible.



Correct storage on site is essential. Store in a clean, dry area, in the same conditions as are expected when the building is occupied. Cover to protect against dirt and risk of damage from other trades working.

Store panels stacked flat and level, on supports. Supports should be timber, covered with plywood or cardboard to avoid marking the panel surface, minimum 100mm wide x 50mm deep, across the full width of the panel. There should be three such supports, equally spaced, one across the centre and one 300mm from each end.

Veneered surfaces should not be exposed to strong light or direct sunlight as this could cause differential fading and shrinkage / cracking of the veneer.


Scheme matching of veneers means that it is essential for doorsets and panels to be installed in the correct positions.

In many cases, each panel is designed for installation in a specific location in the building or in a specific sequence, and must be hung with the correct face visible on each side – refer to instructions on the product’s Shadbolt bar code.

In matched schemes all panels are individually identified to show their intended positions, and installers must be made aware of the need to fit each one in the correct location – refer to instructions on the product’s Shadbolt bar code.


Door panels are supplied to exact finished sizes and must not be trimmed on site.

Where there is uncertainty in wall thicknesses, adjustable split frames can be supplied to allow fixing adjustment on site.

Please contact Shadbolt in the first instance if you have any questions or queries.


Regular inspection and maintenance are essential to ensure that panels retain their design performance throughout their life. Full recommendations are available from Shadbolt.


Veneered panels should be cleaned by wiping with a damp cloth; where necessary a mild detergent solution may be used. Abrasive or chemical cleaners must not be used.


If veneered products should be accidentally damaged during or after installation, repair is usually feasible. However, exact matching of the veneer may not always be possible. Consult Shadbolt for advice.
