Which is better for a metal building?

The BlueTex Pro 2mm Super Wide. Its 62-inch width spans 60-inch on-center purlins with a 2-inch overlap, and the foam core adds a vapor barrier. The Reflectix roll is only about 39 inches wide and would need seams everywhere.

Is the Reflectix roll enough to insulate a garage?

Only for spot work. One roll covers about 54 sq ft, so a full garage ceiling or wall needs several rolls, and the thin bubble core gives little R-value on its own.

Does the BlueTex cost more than it is worth?

At $199.00 for 300 sq ft it works out to about 66 cents per square foot, versus about $1.24 per square foot for the Reflectix at $67.00 for roughly 54 sq ft. For a large metal building the BlueTex is the better value per square foot.

Which reflects more heat?

Both are rated at up to 97% radiant heat reflection, so reflection is a tie. The difference is the core: BlueTex uses 2mm closed-cell foam, Reflectix uses a polyethylene bubble layer.

Can I use the Reflectix on ducts and pipes?

Yes. It is thin, flexible and self-adhesive, which makes it easy to wrap ducts, pipes and radiators. The BlueTex roll is too wide and stiff for that kind of work.

BlueTex is built for permanent installation under purlins and is fastened with tape and screws, so it holds up in metal buildings. Reflectix is a lighter foil wrap best suited to spot jobs that may be redone.
