Is this worth it over plain double-sided foil?

If the white face will be visible, yes. It reflects about the same 97% as double-sided foil and adds a clean white finish on the back. If looks don't matter, plain foil does the same job.

Can I use it in an attic?

Yes. The micro-perforations let moisture pass through, which is why perforated barrier is the type recommended for attics. Keep at least a 1/2 inch air gap on the foil side.

Does it replace fiberglass insulation?

No. Its R-value is about R-1. It blocks radiant heat but does not provide the bulk R-value that fiberglass or foam does.

Which side faces which way?

The foil side must face the air space, at least 1/2 inch deep. The white side faces the other direction, typically the room or living space.

What sizes and weights are the rolls?

Each roll covers 1,000 sq ft, either 4' x 250' or 5' x 200', and weighs about 27 lb. That is manageable for one person to carry.

The best new price seen is $99.00 at EcoFoil as of November 4, 2026. Four stores list it new, so compare roll sizes before buying.
