3. Perfectly watertight in 5 steps
- Thanks to their unique composition, the moulded E-Board® insulation panels are 100% waterproof.
- The unique tongue-and-groove system ensures that the panels snap together seamlessly.
- The PU bonding between the panels creates a sealed insulation shell.
- The sides of the panels are lightly chamfered, resulting in a V-notch on the front of each seam, which is always filled by waterproof adhesive mortar.
- A semi-circular groove in the tongue of the panel ensures that every single droplet that still manages to penetrate, is removed.
