Single Bubble Insulation

Single Bubble insulation is an economic alternative compared to our double bubble product. It is also 96% reflective which means it does the exact same job at preventing radiant heat gains in your building. With only a single layer of polyethylene bubbles, we recommend single bubble insulation for less extreme climates.

Double Bubble Insulation

Our most popular bubble foil insulation is used for applications in metal buildings, pole barns, basements, crawl spaces, and many other places that require a vapor barrier. Double bubble foil has a double layer of polyethylene bubbles that acts as an extra thermal barrier to prevent condensation.

Between Joist Insulation

Between joist insulation is made from the same material as our top-selling double bubble product. The only thing that makes this product special is that it is pre-cut to either 16" or 24" widths and includes staple tabs along both sides for easy attachment between floor joists.

Ultra CBF Under Slab Insulation

Designed specifically for installation under concrete slabs and radiant floors. The metalized foil in under slab insulation is sandwiched between a layer of polyethylene bubbles on each side to protect the reflective coating. This is the only product that we sell that is rated for use under concrete slabs and as reflective radiant floor insulation.
