Allowances for larger and taller mass timber buildings have been approved as part of the National Fire Protection Association (NFPA) 5000, Building Construction and Safety Code, and, where applicable, NFPA 101, Life Safety Code.
To be approved for use in building construction, products need to be tested and evaluated to the requirements of building codes by appropriate third-party entities. In the rapidly evolving market for building materials, a manufacturer’s ability to demonstrate its products are code-compliant is critical to gaining approval for use in the thousands of jurisdictions across the nation. This code evaluation process can be time-consuming, and can impact timelines for introduction of products into the market.
Many designers and specifiers understand controlling air, vapor, and thermal transfer helps mitigate moisture problems within the building envelope. Moisture accumulation is a performance adversary that can lead to structural deterioration, finish damage, organic growth, and reduced building longevity.
