Natural Products: Corian
Corian is the original solid surface material; a 12mm thick premium through-coloured mineral composite backed by 25mm moisture resistant MDF subframe.
With over 50 years of development, Corian as a material boasts one of the most well established portfolios. Their range of styles is constantly updated, and covers a wide range of styles from clean block colours to complex swirling patterns.
Below, we explore some of the key points to consider when purchasing a veined Corian worktop.
Properties of Veined Corian Worktops
Veining characteristics vary for each material in the range, but can include directional flow, swirls, highlights, lowlights and can create mottled or marbled appearances. Smaller samples will often not be fully representative of full-sheet veining, and veins can differ between worktops within the same batch.
Drainer grooves and recessed drainers will each show a continuation of the same veined pattern. As the colouration is three-dimensional, drainer groove configurations will show a distortion in any straight-line veins on the top surface.
Veined surfaces cannot be repaired as effectively as homogeneous worktops. Typically, and particularly for worktops which have cracked due to thermal shock, sections of matching material will be inserted and affixed. The random finish of veined surfaces means these joins would be visible.
Colours of Corian are quality controlled between batches. Because the range is capable of large-scale sweeping veining patterns, smaller samples may not be fully representative of the colours found in an installed worktop. Colours viewed in print or by screen may also not be fully representative of actual samples.
Joints & Shaping
Corian as a material is capable of seamless joints. Veined patterns will however have a distinct discontinuation at the point where two sections meet. Corners are joined using an offset butt joint, to strengthen the corner against stress. Corian can also be Thermoformed, which may cause mild warping of the designs.
Sheet Size Limitations
Sheets of Corian have a maximum width of 760mm, and a maximum length of 3658mm, some of which may be reserved for creating offset-corner joints.
In some instances, Corian may be joined along the width, for example if a design exceeds the slab dimensions or an extended corner is installed. In these instances, an S-Joint will be used to try to avoid more obvious straight-line joints.
Colour matched bowls
Corian bowls are available in limited block colours, while Trevino & Primo Classic bowls can be manufactured to match any Corian style. Where these join, there will be a noticeable breakage in any veining patterns.
