Foil Fiberglass Vinyl Insulation – Product Details
Premium Reflective Insulation with Fiberglass Core
This Foil Fiberglass Vinyl insulation roll combines the power of reflective technology with the proven thermal stability of fiberglass. Designed for both commercial and residential use, it effectively combats radiant heat, conductive heat transfer, and moisture challenges in demanding environments.
Structure and Composition
The product consists of a central fiberglass insulation core laminated on one side with a reflective aluminum foil and on the other side with a durable white vinyl facing. This multi-layer construction allows it to serve dual purposes—thermal insulation and surface protection.
Material Breakdown
Aluminum Foil Face: Reflects up to 95% of radiant heat.
Fiberglass Core: Provides bulk insulation with high thermal resistance.
White Vinyl Backing: Adds strength, puncture resistance, and clean visual finish for exposed applications.
Performance Highlights
Foil Fiberglass Vinyl insulation delivers exceptional performance in settings where both thermal control and surface durability are required. It resists damage from compression, maintains a strong R-value over time, and adds reflectivity to improve HVAC efficiency.
Key Performance Metrics
Size: 6 ft wide x 125 ft long (750 sq ft per roll)
Excellent Radiant Heat Barrier: Reflective foil enhances overall insulation effectiveness.
Consistent Thermal Resistance: Fiberglass maintains R-value in extreme temperature variations.
Durable Finish: Vinyl layer provides protection during and after installation.
Installation Advantages
Foil Fiberglass Vinyl insulation is engineered for easy handling and installation, even in large-scale applications. Its flexible design makes it compatible with a wide range of structures and systems. For more on installation, see Detailed Installation Instructions
