FACTORS CONSIDERED IN DARK COLORED WINDOWS AND SIDING - Part I - THE COMPLEX COMBINATION OF REQUIRED VINYL PROPERTIES

摘要

Successful dark colored windows and siding require pigmentation for long-term durability and for solar reflection to avoid excessive temperatures, a durable polymer, limits on coefficient of linear thermal expansion to minimize buckling stresses, formulations with excellent initial and retained impact resistance, and a polymer base with sufficient glass transition temperature and buckling resistance to maintain shape at maximum solar heating for several decades of time.
