Key Specifications

Why Choose Comfort R-38?

Maximum Energy Efficiency: The dense fiberglass structure minimizes heat transfer, helping you maintain consistent indoor temperatures.

Acoustic Comfort: Beyond thermal benefits, the high-density fibers act as an excellent sound dampener, reducing noise between floors or from the outside.

Easy Installation: Pre-cut to 23-inch widths, these batts friction-fit perfectly into standard 24-inch on-center wood framing without the need for specialized tools.

Fire Resistant & Non-Corrosive: Naturally non-combustible and does not require chemical fire retardants that can corrode pipes or wires.

Best Applications

Cathedral Ceilings: Fits perfectly in deep rafter cavities.

Floor Joists: Ideal for insulating over unheated crawlspaces or basements.

Attics: Use as a base layer or a "top-off" to meet modern building codes.

Pro Tip: When installing, ensure a snug fit without compressing the material. Compressing a 9.5" batt into a smaller space will actually lower its effective R-value.
