Corian Joints

Corian is the original solid surface material, developed by materials specialist DuPont in 1967. With over 50 years to perfect the delivery of their premium worksurfaces, DuPont has developed specific instructions as to how their products should be delivered. We at Sheridan, as a Corian Quality Network Industrial Partner, are committed to fulfilling DuPont’s requirements, ensuring Corian worksurfaces installed by our teams are long lasting, great looking, and fully covered under warranty.

Corner Joints

In corners we always use Mitred Shop Joints for the veined design to flow around the corner. This means the joints themselves are produced in-house at Sheridan by specialist fabricators, offering much more flexibility and control over this difficult section.

Also in these corners we complete a normal site joint (completed in the home) on one side of the mitred joint that will join to the rest of the worksurface on that side with minimal disruption to the veined design.


Joints to increase the Width of a worktop

For worksurfaces wider than the sheets (wider than 700mm), we use an “S” Joint to disguise the joint.

“S” Joints have a less conspicuous joint line than a straight join, making them a great solution to hide where two pieces are joined together.

Joints to increase the Length of a worktop

For worksurfaces generally longer than 3m, we do not use “S” Joints to join two lengths together. We use a standard butt joint, which is completed in the home. This is the correct type of joint required to maintain the Corian warranty.

We also use a standard rebated front edge where the front face fits into the thickness of the top surface exposing only half (6mm) of it’s thickness which minimises any visible differences between the front face and the top surface.

Other Considerations

Please note, some veined Corian styles may differ in terms of the final appearance of joints. These include but are not limited to:-

  • Translucency – The Onyx range for example mixes opaque and translucent colours. Where translucency permeates the worksurface, the glue line may be visible.
  • Veining Width & Style – Some Colours contain more variation in pattern and colour which will naturally make joins more visible. See the article on Colour Variation for more information.
  • Upstands – Both the above considerations also affect Upstands, which are produced with a straight join.
