PlenaLith

DESCRIPTION
PlenaLith is a waterproof membrane featuring a monolithic film that delivers superior water tightness and effective protection against UV rays and heat.
Thanks to its monolithic structure, it is completely airtight and acts as a wind barrier, while still allowing internal moisture vapor to escape, thereby reducing the risk of condensation.
The material maintains high mechanical strength over time, even when exposed to chemical agents, offering an ideal balance between robustness and breathability.

APPLICATION
PlenaLith is designed for use as a secondary protective layer in pitched roof applications. It is installed directly above the insulation panel or continuous substrate, ensuring active and long-lasting waterproofing even in harsh weather conditions like strong winds or driving rain.
Its compact and continuous surface prevents water and air ingress, while controlled breathability allows moisture vapor to escape, preserving the insulation’s long-term performance.
Like all Aplena products, PlenaLith is quick and easy to install, even in challenging environmental conditions, thanks to its flexible material and dimensional stability.
PlenaLith is a technical choice for high-performance roofing systems requiring maximum resistance, energy efficiency, and long-lasting protection.
