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
Installation Benefits
Resists Tearing and Sagging: Maintains shape and structure over time.
Clean Interior Appearance: Vinyl surface gives a finished look, reducing the need for additional covering.

Applications
Versatile Use Across Building Types
Foil Fiberglass Vinyl insulation is ideal for a wide range of commercial, industrial, agricultural, and residential construction projects. Its reflective and insulative properties make it especially valuable in structures where both thermal efficiency and durable finish are required.
Metal Buildings and Pole Barns
This product is a top-performing solution for insulating metal roofs and walls in pre-engineered buildings. It addresses the two major concerns in metal structures—radiant heat gain and condensation.
Benefits in Metal Structures
Reduces heat buildup in hot climates
Helps prevent sweating and moisture drip
Creates a more stable indoor temperature year-round
Agricultural and Livestock Facilities
In barns, poultry houses, and equipment storage buildings, the vinyl-facing provides a cleanable, durable surface that can withstand tough agricultural conditions.
Benefits in Agricultural Use
Withstands exposure to humidity and cleaning agents
Helps protect livestock from temperature extremes
Improves lighting by reflecting interior light
Warehouses and Commercial Interiors
In commercial buildings, this insulation provides energy savings while also enhancing interior aesthetics. The white vinyl finish delivers a polished appearance when left exposed.
Common Commercial Applications
Warehouse walls and ceilings
Loading dock covers
Retail backrooms or service corridors
Exposed insulation in utility areas
Duct and HVAC System Wrap
The fiberglass core and foil facing make this product ideal for wrapping ducts and mechanical equipment. It helps maintain temperature in air systems and reduces HVAC energy loss.
HVAC-Related Applications
Ductwork insulation in unconditioned spaces
Mechanical room enclosures
Pipe and conduit insulation
Residential Use
While more commonly seen in commercial settings, Foil Fiberglass Vinyl insulation is also suitable for residential garages, workshops, and crawl spaces, particularly where a clean appearance is desired without extra finishing.
Residential Benefits
Keeps garages cooler in summer and warmer in winter
Adds a polished finish to home workshops
Reduces energy loss in crawlspaces and basements
Product Benefits
Dual Thermal Protection: Reflective + Bulk Insulation
One of the standout advantages of this product is its hybrid insulation structure. The aluminum foil reflects radiant heat, while the fiberglass core reduces conductive heat flow—delivering powerful thermal performance in a variety of conditions.
Key Thermal Advantages
Reflects up to 95% of radiant heat: Prevents heat penetration in summer and retains warmth in winter.
Stable R-Value: Fiberglass maintains insulating power even in extreme hot or cold conditions.
Improves HVAC Efficiency: Reduces the load on heating and cooling systems.
Vapor and Moisture Control
Moisture management is essential for structural longevity and comfort. This insulation helps prevent condensation, protecting building materials and reducing mold risk.
Moisture-Resistant Benefits
Vinyl Facing Resists Condensation: Especially useful in metal buildings and high-humidity environments.
Barrier to Humidity and Airflow: Helps maintain consistent indoor conditions and lowers energy costs.
Clean and Durable Surface Finish
With its white vinyl facing, this insulation offers more than thermal protection—it contributes to a clean, finished look. This makes it perfect for exposed installations where both performance and appearance matter.
Aesthetic and Structural Advantages
Professional Appearance: Bright white surface improves lighting and aesthetics.
Puncture-Resistant Surface: Withstands construction wear and long-term exposure.
Washable Finish: Easy to clean in dusty or agricultural environments.
Long-Term Performance and Reliability
Engineered to hold up under harsh conditions, this insulation maintains its shape, R-value, and physical integrity over time. It won’t sag, compress, or deteriorate with age.
Reliability Benefits
Minimizes Air Gaps and Voids: Maintains consistent insulation performance.
Won’t Degrade or Settle: Ideal for installations where long-term value is a priority.
Fire-Resistant Core: Fiberglass naturally resists flames, enhancing safety.
Installation Efficiency
Designed with installers in mind, this roll is both flexible and tough. It can be quickly cut, shaped, and mounted in tight or awkward spaces without tearing or damage.
Installer-Friendly Benefits
Lightweight and Maneuverable: Reduces fatigue and speeds up project timelines.
750 sq ft Coverage Per Roll: Fewer seams mean faster installation and reduced air leakage.
Versatile Application: Compatible with walls, ceilings, ducts, and more.
