What to know before buying

Listing details to confirm

The listing describes the material as both multi-layer reflective aluminum or high-density aluminum film and as 50%PET, 50% Mylar.

Customer feedback additionally differs on the size, including a report that it was only 14'5" long despite the listed 48 in x 10 ft. Confirm the product dimensions and material details against the selected listing before planning a fitted installation.

Negative themes

Some customer feedback describes the material as thinner than expected.
