UL Environment, Inc., a business unit of Underwriters Laboratories (UL) is releasing standard requirements, UL ISR 102, for door slabs.
UL ISR 102 provides requirements to evaluate the life-cycle environmental impacts related to producing a variety of door types: materials management, energy use, water use, manufacturing and operations, health and environment, product performance, product stewardship, and production practices.
Perhaps this will help fill the existing void of reliable information for evaluating the relative sustainability of construction related materials and products.
