The visible join on the surface of the panel will vary depending on the joint style of the panel:
- flush joint
- contrast joint
- v-groove joint
There are pages with information regarding these different joint types on the website and the flush joint page has just been re-vamped with some new images to show in more detail the appearance of this type of joint.
The joint types refer only to the visible surface and do not affect the performance of the joint. We would always recommend running a thin bead of silicone inside the groove prior to installation in a shower area just to ensure no water is forced through the joint (the joint relies on the springiness of the plastic so if you took a power shower spray head and pointed it at the joint you could force the joint apart with a powerful enough jet)
