Frequently Asked Questions
What do the bubbles do?
The layer of bubbles provides a thermal break between hot and cold air, and helps eliminate condensation from forming in your structure. Double Bubble has two layers of bubbles for extra condensation prevention. Double Bubble Reflective Insulation is typically used in the northern states where temperature differences inside vs. outside your structure are extreme, typically during cold, frigid winters.
How much tape do I need?
1 roll of tape will be needed for every 500 sq ft of reflective insulation. It's important to tape the seams between adjoining sheets—never use tape to attach the product directly to your structure. Taping the seams creates a vapor barrier when installed properly, and helps ensure the reflective properties of the insulation.
Which tape do I choose?
- For Foil/Foil finishes, choose Metalized Reflective Insulation Tape
- For White/Foil finishes, choose White Reflective Insulation Tape
Is between joist insulation available in a white finish?
At this time, Between Joist Insulation is only available in a Foil/Foil finish. If you'd like a White/Foil option added to our catalogue, please let us know by calling 888.349.3645 or filling out this form. In the mean time, if you'd like a white finish you could cut down a 48" roll of White/Foil Double Bubble to size, which is essentially the same product but without staple tabs.
How do I install Between Joist Insulation?
In most cases, Between Joist Insulation can be installed with a staple gun directly to the joists. The staple tabs make this process easy when joists are spaced by 16" or 24". Complete installation instructions can be found on this page.
