Description
Insul-Barrier R-12 Wall Insulation System – Insulation + Vapor Barrier in One
The Insul-Barrier Wall Insulation System is a high-performance solution designed to insulate crawl space and basement walls while controlling ground moisture. This multi-layer system combines reflective technology, closed-cell foam, and durable polyethylene skins to deliver both thermal resistance and vapor protection in a single, easy-to-install product.
Each 4′ x 25′ roll covers 100 square feet and is engineered for long-term performance in demanding environments.
Key Features & Benefits
R-12 Thermal Performance
Provides strong insulation to help regulate temperatures and reduce heat loss or gain in crawl spaces and basements.
Built-In Vapor Barrier
Integrated polyethylene layers block vapor migration, helping protect your structure and improve air quality.
Multi-Layer Construction
Engineered with reflective surfaces, closed-cell foam, and bubble insulation for consistent thermal and moisture protection.
Durable & Tear Resistant
Reinforced design resists damage during installation and long-term use in crawl space environments.
Bright White Interior Finish
Improves visibility in crawl spaces, making inspections and maintenance easier.
Flexible & Easy to Install
Lightweight blanket-style material allows for fast installation around walls, corners, and tight spaces without specialized tools.
Why It Matters
Uninsulated crawl space and basement walls allow heat loss, temperature swings, and vapor intrusion that can lead to mold, structural damage, and poor indoor air quality. The Insul-Barrier system provides a combined thermal and vapor control solution, helping stabilize your environment and improve overall energy efficiency.
