Comfort R-38 High-Density Fiberglass Insulation Batt

Dimensions: 9.5" x 15" | Coverage: 19.8 sq. ft.

Upgrade your home's thermal envelope with the Comfort R-38 Fiberglass Batt. Engineered specifically for high-performance applications, this insulation provides a massive R-38 thermal resistance in a compact 9.5-inch profile. It is the ideal solution for cathedral ceilings, crawl spaces, and floor systems where depth is limited but energy efficiency is a priority.

Key Features

Superior Thermal Performance: Delivers an R-38 value to keep your home warmer in winter and cooler in summer, significantly reducing utility costs.

High-Density Design: At 9.5 inches thick, it packs more insulating power into a smaller footprint than standard R-38 batts (which typically require 12+ inches).

Perfect Fit: Pre-cut at 15 inches wide to fit snugly between standard joists or studs spaced 16 inches on-center.

Moisture & Fire Resistant: Naturally non-combustible and designed to resist moisture buildup, protecting your structure from mold and mildew.

Acoustic Comfort: Beyond temperature control, this high-density fiberglass acts as an excellent sound dampener, reducing noise transfer between floors.

Installation Tip

For the best results, ensure the insulation is installed without compression. Tucking or folding the material can reduce its R-value. Use insulation supports (wires) if installing in under-floor applications to prevent sagging over time.
