Lamella boards

Lamella boards are insulation boards designed for use on curved or irregular roof forms where standard rigid boards would bridge across the surface rather than conform to it. The lamella construction allows the board to flex into curved geometries while maintaining the required thermal resistance and providing a consistent substrate for the membrane.

Where used: Used on barrel vaults, domed roofs and any curved or compound-curved roof geometry.

Integrated within a full tapered scheme, they support long-term roof performance and durability. Contact Gradient today to discover how Lamella boards can be incorporated as part of your flat roof tapered scheme.
