How do I know which size thickness of panel I have?

How do I know which size thickness of panel I have?

Below is a quick description of the panels to help you choose the correct size:

10mm internal corner trim

Often referred to as shower wall panels the PROPANEL® XL and PROPANEL® LUUX panels are stronger 10mm thick panels. These require the more rigid 10mm internal corner trim for fitting.

8mm internal corner trim

Standard decorative cladding tends to come in 8mm thickness. To correctly fit you will need to match the panel with 8mm internal corner trim.

5mm internal corner trim

Thinner trade value cladding panels come in 5mm thickness. These are the thinnest and most cost-effective decorative panels available. They require smaller 5mm internal corner trims to fit correctly. Any other size will be too big making it loose for the fitting. This will compromise your finished waterproof seal resulting in a possible leakage.
