Which is better for an attic?

Both are perforated and breathable, so both suit attics. The EcoFoil is the cheaper way to cover a small attic; the BlueTex covers twice the area per roll and has a white face.

Is the BlueTex worth the extra money?

Only if you need 1,000 sq ft rolls, a heavier foil, or a white visible face. Per square foot, the EcoFoil at $69.90 for 500 sq ft at Target as of November 6, 2026 is much cheaper than $194.95 at AtticFoil Radiant Barrier.

Do both block the same amount of heat?

Yes, close to it. EcoFoil states 96-97% radiant heat blocked; BlueTex states 97% reflectivity. The bigger difference is coverage and weight, not reflectivity.

Which is easier to install?

The BlueTex is heavier and stronger, so it resists tearing, but it needs a 1/2 in air gap on the foil side. The EcoFoil is thinner and lighter, and its 500 sq ft rolls are easier to handle alone.

Can either be used as a vapor barrier?

No. Both are perforated and breathable. EcoFoil lists 8.5 perms; BlueTex says it is not a vapor barrier.

How much do I need for a 1,000 sq ft attic?

Two EcoFoil rolls (about $139.80 at Target as of November 6, 2026) or one BlueTex roll ($194.95 at AtticFoil Radiant Barrier as of November 6, 2026).
