What is the roll size and coverage?

The roll is 4 ft by 32.8 ft, about 131 square feet. That covers a long wall run or several duct wraps with few seams.

Does the foil facing replace a vapor barrier?

The foil reflects radiant heat and resists moisture, which helps in many wall and roof assemblies. In cold climates check local code, since some builds still call for a separate vapor retarder.

What R-value does it have?

No R-value is stated for this roll. Thermal performance depends on the fiber thickness, so measure the thickness and match it to the R-value your project needs.

Can I use it around ducts and pipes?

Yes, the roll is meant for ducts as well as walls and roofs. Wrap tightly and tape the foil seams so the reflective face stays continuous.

Is it safe to handle without gear?

No. Glass fibers irritate skin, eyes and lungs, so wear gloves, long sleeves, goggles and a respirator, and work in a ventilated space.

How does it compare with unfaced batts?

It adds a reflective, moisture-resistant face that plain batts lack, and the roll covers long runs with fewer seams. Unfaced batts are simpler where a separate vapor barrier is already planned.

Our take on the Wellco Foil-Faced Fiberglass Insulation Roll

This is a foil-faced fiberglass insulation roll, 4 ft wide by 32.8 ft long, roughly 131 square feet per roll. The glass fibers handle thermal and acoustic insulation, while the foil face reflects radiant heat and resists moisture. It suits walls, roofs and duct wrapping, and it competes with unfaced batts and foil-backed rolls on the same jobs. The foil facing is the main edge over plain fiberglass, which needs a separate vapor barrier in damp spots.
