Every long-lasting deck starts with a solid foundation. The Lunawood Insulation Band provides essential protection for the substructure, preventing ground moisture from rising into the decking boards and ensuring lasting performance in all climates.

Applied directly onto the joists, Lunawood Insulation Band acts as a waterproof layer between the substructure and decking boards. It prevents moisture accumulation, reduces the risk of decay, and improves the lifespan of the entire deck.

Especially in outdoor applications, where wooden structures are constantly exposed to changing weather conditions, this small addition makes a significant difference.

By ensuring proper airflow and blocking capillary moisture from the ground, the Insulation Band helps maintain the stability, aesthetics, and durability of Lunawood Decking for years to come.
