What is the difference between rigid insulation sheets and batts?
Foilboard® GREEN rigid board insulation will maintain the same thermal performance (R-value) for the life of the insulation panel. It will not sag and it will not delaminate. Foilboard® Australia backs its Foilboard® GREEN with a 25 year performance guarantee. Fully endorsed by Standards Australia, the Foilboard® GREEN rigid insulation panel is the premium insulation product in its market, both in manufactured quality and product performance and that is why it is backed by a 25 year performance guarantee. This durable rigid panel is specifically designed to achieve exceptionally high thermal values, making it the ideal product. Unlike traditional bulk insulation and blankets, this rigid panel will not shrink, sag or droop, ensuring that the building performs to its optimal thermal value from day one, to year 25 and beyond. The insulation board cost depends largely on its R-value (also known as R-rating) however bulk order discounts are also available.
