Should I purchase a single-source manufacturer building envelope system, or is it acceptable to use materials from different manufacturers within the same system?
When purchasing a Building Envelope system, such as deck systems, roof systems, weather barrier systems (including single source manufacturer window and door flashings), as well as below-grade, planter, and water feature systems, it is crucial to choose complete systems from a single source manufacturer. These full systems are thoroughly vetted, tested, and verified to work together, ensuring chemical and adhesion compatibility that is suitable for the specific environment.
Using a single-source manufacturer’s complete system is the only way to obtain watertight warranties and predictable performance. Mixing materials from different manufacturers within the same system should be avoided, as even materials from the same manufacturer can sometimes be incompatible.
Carefully reading and adhering to the manufacturer’s specifications is critical, even when using a complete system. In some cases, additional measures, such as using epoxy divorcing layers or aluminum tape, may be required to separate materials and maintain compatibility.
California Consultants can peer review your project’s design to ensure that the building envelope systems have been purposefully selected and specified to achieve a watertight structure with comprehensive watertight warranties.
