  2. Knauf Exterior Wall with AQUAPANEL® Technology

Do I need a Water Barrier if I install AQUAPANEL® Cement Board directly on steel?

Yes! Here is an explanation of the purpose of the AQUAPANEL® Water Barrier.

Yes. The vast majority of climatic conditions require a water barrier in the facade due to the consequences of water penetration.

Condensation can form in exterior components at any time of the year from convection or vapor diffusion. A wall system must be structured in such a way to ensure that moisture from convection and diffusion is safely directed outside. The application of water barrier is necessary in all the Knauf Exterior Wall systems.

For special cases, please consult your local AQUAPANEL® technical department.
