Radiant Barrier Roofing Insulation
Stop Heat Before It Enters Your Building
ES® reflective roofing insulation blocks solar radiant heat at the roof deck before it enters attic and interior spaces. By stopping heat at the source, it helps lower attic temperatures, improve indoor comfort, and reduce cooling demand.
This radiant barrier roofing system works in both shingle and metal roof assemblies, helping control attic heat and improve overall building energy efficiency.
Reflective roofing insulation blocks solar heat at the roof deck, lowering attic temperatures, improving indoor comfort, and reducing cooling costs. Perfect for residential, commercial, agricultural, and metal roofs.
Reduce Roof Heat Gain
Solar radiation is one of the largest contributors to unwanted building heat. Installing a roof radiant heat barrier over roof decking and under shingles in residential shingle roof systems limits heat transfer into attic and living spaces.
Improve Indoor Comfort
A properly installed roof radiant heat barrier over roof decking and under shingles reduces attic heat buildup and improves HVAC efficiency.
Lower Cooling Costs
Reflective roofing insulation reduces heat gain through the roof system, decreasing demand on air conditioning equipment.
What Is Radiant Barrier Roofing Insulation?
Reflective roofing insulation is a reflective material installed at or near the roof deck to reduce heat transfer caused by solar radiation, functioning as a roof radiant barrier that helps control attic heat gain.
In many roof systems it functions similarly to an attic radiant barrier, helping prevent excessive heat buildup in attic spaces. Depending on the roof design, radiant barriers may be installed above the roof deck, inside the attic, or in both locations. In attic installations, attic foil insulation helps reflect radiant heat and improve overall thermal performance.
Installed over roof decking and under shingles, or beneath metal roofing panels, it helps:
- Lower attic temperatures
- Reduce HVAC load
- Improve thermal performance
- Protect roof assemblies
In homes with vaulted or sloped roof assemblies without attic space, radiant barriers are typically installed directly beneath the roof deck as part of a cathedral ceiling insulation system.

Benefits of Radiant Barrier Roofing Insulation
Roofs absorb significant solar heat throughout the day. Without a reflective barrier, that heat radiates downward into attic and interior spaces, increasing cooling costs.
ES® radiant barrier insulation for metal roofs and deck-mounted systems provides energy-efficient roofing that reflects heat away before it impacts indoor conditions.
Depending on the product selected, ES® materials also assist with:
- UV resistance
- Moisture management
- Vapor control within roof assemblies
Tested and Code-Compliant
✔ ASTM E84 Fire Performance
✔ ASTM E2599 Radiant Barrier Performance
Designed for long-term thermal performance without maintenance.
INSTALLATION APPLICATIONS
Installation varies based on roof type, climate zone, and building design.
Shingle Roof Systems
Installed above roof decking and beneath asphalt shingles this energy-efficient roofing solution reflects heat before it enters attic spaces.
Metal Roof Systems
Radiant barrier insulation for metal roofs installed beneath metal panels to reduce radiant heat gain in metal buildings.
Agricultural and Commercial Roofs
Installed beneath roof panels or integrated into roof assemblies, reducing heat gain in warehouses, barns, and commercial structures.
Long-Term Roof Assembly Protection
ES® reflective roofing insulation supports durability by helping resist:
- Moisture-related performance issues
- Conditions contributing to fungal growth
- Pest intrusion pathways
For complete building envelope performance, pair roof insulation with reflective house wrap insulation to control heat transfer through exterior walls, while basement insulation helps reduce heat loss and moisture from below.
