Embracing a broader perspective

LCAs and EPDs are good tools to assist in determining sustainable insulations; however, calling manufacturers to obtain more information such as type of energy use, facility location, material efficiency, and recycling protocols will ensure the best sustainable design decisions are being made. There is no question that thermal insulation is a requirement for building enclosures.

In the context of designing for the present and future, it is essential to think beyond the conventional boundaries and explore other aspects of thermal insulation that might not have received adequate attention before. This broader perspective allows for more comprehensive and innovative approaches to be adopted. The manufacturing and transportation impacts of the various types of insulation are important considerations in the goal for more energy-efficient design and construction.
