Double Bubble

Polynum™ Double bubbles products consist of a core of two layers of bubbles to enhance Polynum™ reflective insulation performances when double bubbles are preferred. The presence of second bubble layer contributes to Polynum™ “cushion” effect for better noise absorption ()  The classical double bubbles format is: Aluminum/Bubbles/Bubbles/Aluminum, or, Aluminum/Bubbles/bubbles/Closing sheet.

Our double bubbles products are delivered with stapled (sealed) edges for ease of installation.

In order to ensure durable performances in various conditions, our products are designed and manufactured with unique recipes enable us to meet today’s constructions standards and requirements. Our products are tested in leading international laboratories for delamination, corrosion, cracks, fungus, shrinkage and strength to guarantee our products performances.

The Noise Reduction Coefficient (commonly abbreviated NRC) is a scalar representation of the amount of sound energy absorbed upon striking a particular surface. An NRC of 0 indicates perfect reflection; an NRC of 1 indicates perfect absorption.
