Circa column casing technical information


Heat and pressure are applied to bond layers of plywood veneers with a finishing kraft paper and compensating balancer to produce a strong and lightweight profile, which retains consistent shape with good rigidity and integral strength.

The manufacturing process ensures that a low moisture content of around 7% is maintained to provide greater stability. To ensure an effective bond is achieved and the material retains high structural integrity, a type MR (moisture resistant) adhesive is used which conforms to BS 1204:1979.

As standard, all Circa column casings are manufactured using UKTR compliant and sustainably sourced timbers. All dimensional tolerances can vary by +/- 4mm and the nominal material thickness tolerance is +/- 1mm.

Location and installation

Circa pre-formed plywood casings are extremely versatile and designed for interior use only due to the nature of the materials and finishes used in their construction. Fixings are concealed by an extruded aluminium feature joint incorporating a colour matched insert.

The immense scope of finishes available and the fact that they are durable, easy to install and cost effective, makes them one of the most popular column casing solutions.

Fire resistance and spread of flame

The substrate conforms to BS 476-7:1997 Class 2 spread of flame. When used in conjunction with a fire-retardant laminate or lacquer, bonded with an appropriate adhesive system, conformance to Class 1 spread of flame is achieved.

Two-year guarantee

All products in our Circa range carry a two-year guarantee, as standard. This covers the casings against the de-lamination of plywood veneers and bonded decorative finishes, when used under normal conditions, and is effective from the date of purchase.

A range of finishes is available to meet individual specifications, including plain casings for on-site decoration together with high pressure laminates for increased durability and improved aesthetics. Please click here to go to the ‘Finishes’ section for more information.
