Innergy Rigid Thermal Reinforcements are the high-performing, energy efficient alternative to aluminum inserts.

• Made from advanced fiber-reinforced polyurethane
• Custom designed to slide easily into energy-efficient window and door frame chambers for greater support and insulation
• Virtually impermeable to cold or heat (-40° F to >200° F) and reduces condensation
• Result is a new, more energy-efficient system with all the strength and structural reinforcement of aluminum, but with a whole new set of high performance benefits.
