Silicone’s excellent aging characteristics, resistance to ultraviolet (UV) light and weathering, and long effective life span has made pre-cured sealants a popular material for construction-related applications.
For many years, designers and contractors have espoused tilt-up construction for providing a more airtight building envelope than competing wall assemblies, such as wood and metal stud wall, metal siding, and concrete and brick masonry. Now, code language may also be a supporting factor.
Providing adequate rainwater management and control for air, vapor, and heat flow through the building enclosure is critical to long-term performance and durability. In contemporary wall assemblies with layered materials, the complexity of coordinating these various demands can be overwhelming.
The majority of large-scale design/ construction projects revolve around a single concept known as the owner’s project requirements (OPR). Developed throughout each project phase, these criteria essentially define the performance specifications for the building as a whole.
