SOL-R-SKIN 

Radiant Barrier Underlayment

SOL-R-SKIN Radiant Barrier Roof Underlayment

PRP Roofing supplies SOL-R-SKIN radiant barrier roof underlayment as part of our premium Florida roofing products lineup.
This patent-pending system combines a high-performance roofing underlayment with reflective foil insulation to create a radiant barrier under the roof deck, delivering some of the highest effective R-values available in a thin underlayment profile.

Designed for use under composite shingles, stone coated metal roofing, clay tiles, and metal roofing systems, SOL-R-SKIN is an ideal upgrade for residential and commercial projects across Florida that need energy savings, comfort, and enhanced fire performance in one product.

What Is SOL-R-SKIN?

SOL-R-SKIN is a next-generation underlayment that blends the weather protection of a synthetic roofing underlayment with the thermal and fire characteristics of advanced insulation.
A highly polished aluminum surface, fiberglass core, and synthetic underlayment are bonded together into a single product, creating a durable radiant barrier beneath the roof covering.

  • Patent-pending hybrid of roof underlayment and reflective insulation.
  • Addresses all three modes of heat transfer: radiation, conduction, and convection.
  • Designed to reduce heat gain, improve indoor comfort, and support energy savings.
  • Engineered to help roofing assemblies meet modern energy and fire code requirements.

 

Class A Thermal Underlayment

SOL-R-SKIN Class A Thermal Underlayment starts with a 99% highly polished, scrim-reinforced aluminum layer, bonded to fiberglass, then laminated to a synthetic underlayment substrate.
The result is a robust radiant barrier underlayment that pairs thermal performance with a high level of fire resistance.

  • Tested thermal performance of approximately R-5.5 (ASTM C1363/C1224).
  • Class A / Class 1 fire rating as tested to ASTM E108 and ASTM E84.
  • Helps meet evolving energy and fire codes when used as part of a complete roofing system.
  • Approved for use under shingles, tiles, metal roofing, and stone coated metal roofing systems.

Compared to older reflective insulations built around bubble or foam cores, SOL-R-SKIN Class A Thermal Underlayment is designed to fit more applications, especially where fire performance and code compliance are a priority.

Code Approvals and Listings

SOL-R-SKIN Class A Thermal Underlayment has passed rigorous fire and performance testing and is listed with several key agencies:

  • Class A burning brand performance for fire barriers.
  • Meets requirements for Wildland Urban Interface (WUI) applications.
  • Listed with CalFire for specific fire-zone use.
  • Listed with Miami-Dade County, Florida Product Approval, and Intertek for code compliance in demanding jurisdictions.

Easy-to-Handle Rolls

SOL-R-SKIN Class A Thermal Underlayment is packaged for efficient transport and installation:

  • Supplied in 4-square rolls measuring 4.5′ x 100′.
  • Approximate 12″ roll diameter and about 45 lbs per roll.
  • Size and weight make it easier to move on site and position on the roof.

 

Sol-R-Skin Composite Underlayment

SOL-R-SKIN Composite Underlayment combines a strong synthetic underlayment with a scrim-reinforced, highly polished aluminum radiant barrier that faces outward to reflect radiant heat before it enters the roofing assembly.

  • Radiant barrier surface has an emissivity of approximately 0.03, reflecting about 97% of radiant heat flow.
  • Lightweight 4.5-square rolls weighing roughly 21 lbs each.
  • Compact roll size (around 5″ diameter) for easier lifting, staging, and handling on the roof.

This composite configuration is especially effective where solar heat gain is a concern and a thin, highly reflective underlayment can help contribute to a cooler roof system.

 

Radiant Barrier Technology and High R-Values

SOL-R-SKIN products are part of a broader family of roofing radiant barriers engineered for high thermal performance.
Instead of relying on conventional packaging-style bubble or foam cores, SOL-R-SKIN uses a refined manufacturing process to create a more rigid, board-like appearance and improved durability.

  • Reflective aluminum surface reduces radiant heat transfer into the attic or roof cavity.
  • Elevated effective R-values compared to many traditional underlayments.
  • Helps reduce cooling loads, particularly valuable in Florida’s hot, sunny climate.
  • Supports energy-efficiency goals when combined with proper attic ventilation and insulation.

Reinforced Durability

Many reflective products rely on glue to adhere facings to a fiberglass or foam core, which can create weak points over time.
SOL-R-SKIN uses a heat-sealing process that bonds the layers into a single, more rigid structure for improved strength and long-term stability on the roof.

 

Benefits for Florida Roofing Systems

In Florida, roofs must handle intense solar radiation, high temperatures, heavy rain, and coastal conditions.
Integrating SOL-R-SKIN radiant barrier roof underlayment into a system can help:

  • Reduce attic and roof-deck temperatures by reflecting a large percentage of radiant heat.
  • Improve indoor comfort and help lower cooling energy demands.
  • Enhance fire performance and code compliance, including in high-risk zones and strict coastal jurisdictions.
  • Pair with advanced roof coverings like stone coated metal roofing, synthetic slate, synthetic shake, and metal panels.

SOL-R-SKIN underlayments can be a key component in a complete high-performance roof assembly for both residential and commercial buildings throughout Florida.
