Paper-Backed Insulation

Definition

Paper-backed insulation is insulation that comes with paper facing on one side, which serves as a vapor retarder.

Purpose

Paper-backed insulation provides thermal insulation while the paper facing acts as a vapor barrier to control moisture migration. This combination helps improve energy efficiency and protect building structures from moisture damage.

Examples of Use

• Wall Insulation: Used in exterior and interior walls to provide thermal insulation and moisture control.
• Attics: Installed in attic spaces to improve insulation and prevent moisture buildup.
• Crawl Spaces: Applied in crawl spaces to enhance insulation and reduce humidity.

Related Terms

• Vapor Barrier: A material that prevents moisture from passing through walls, ceilings, and floors.
• Batt Insulation: Pre-cut panels of insulation commonly used in walls, attics, and floors.
• Faced Insulation: Insulation with a facing, such as paper or foil, that acts as a vapor barrier.

Notes

• Installation: The paper facing should be installed towards the conditioned space to effectively serve as a vapor barrier.
• Types: Available in various R-values to meet specific insulation requirements.
