Let it breathe with Moisture Release Technology (MRT) that allows internal moisture to escape while keeping external water out of the building envelope.
Sahara Excel is a weather resistive barrier designed for contractors and homeowners who understand that a building that breathes creates a drier, healthier building system.
We’ve also made Sahara™ Excel extra tough with Reactive Extrusion Technology, because we know how important durability is to contractors when it comes to installation.
Sahara™ Excel defends all types of buildings from the harshest conditions Mother Nature or anything else can deliver.
Installing Sahara™ Excel with Moisture Release Technology helps keep your projects dried-in during new construction or re-modeling and assists in drawing moisture out of the building envelope for the lifetime of the building system.
