Installing Comfort Shield MLI Installation begins with evaluating the existing attic configuration and determining which installation method best suits the property. Depending on the attic, the material may be positioned directly over existing floor insulation or attached to the underside of the roof decking. Attic To Shingles focuses on creating a consistent thermal layer that works with the home’s existing insulation system rather than unnecessarily replacing materials that are still performing properly. Once installed, the lightweight, durable multi-layer material requires no routine maintenance and continues helping reduce radiant heat transfer. The result is an attic system designed to support lower heat gain, reduced HVAC workload, improved efficiency, and more consistent year-round comfort.
