Green Building & Sustainability
Westile white solar reflective pavers have a standard solar reflective index (SRI) of 79.7 which will help meet most requirements for low slope roof energy efficiency. In addition to providing outstanding durability, Arctic White Ballast Pavers™ from Westile effectively reduce interior heat gain and cooling loads as well as assisting to reduce heat island effect.
Walkways using Ballast Paver start at 16½" wide and can be customized by installing Ballast Paver side by side, creating walkways.
Perimeter Ballasted Application
Ballast Paver used as a perimeter ballast (10 feet minimum) guards against gravel scour and protects the roofing system at it's most vulnerable area.
Fully Ballasted Application
Ballast paver has been wind tunnel tested at Colorado State University and far exceeds the performance of gravel ballast and other paver systems.
Ballast Paver wind engineered systems (Systems I - IV) are designed for new or existing buildings.
