This is a fairly new myth that was recently created from a competing product manufacture and it is completely false. This is their way to redirect the customer to their foam based product which is significantly more expensive than the equally performing reflective bubble insulation products in the market today.Our Reflex-Air bubble insulation products are industrialized products, not basic packaging bubble wrap, that are manufactured to last and maintain the enclosed air space. The independently enclosed bubble layers are sealed with multiple layers of polyester creating closed air bubbles which prevent the loss of air. We are so confident in our products that we offer a 10 year warranty. All our reflective bubble insulation products are available in 16-inch, 24-inch, 48-inch, 72-inch, and 96-inch widths and of varying lengths. We offer straight edge, staple tab and tape tab versions.
