Multi-Layer Reflective Attic Insulation
A lightweight reflective insulation designed for residential attic retrofit applications.
Designed to complement existing insulation.
Perforated reflective aluminum facings are bonded to both sides of a fiberglass core. AttiicELEVATE installs as a supplemental layer, with existing attic insulation remaining in place.
Thermal benefit, in every season.
Summer: reflect heat away.
Helps reduce radiant heat transfer from the attic toward the living space.
Winter: help keep heat inside.
Helps reduce upward radiant heat transfer through the attic assembly.
Illustrations explain the heat-transfer principle, not a guaranteed temperature or energy result. Performance varies by home, climate, existing insulation, attic configuration, ventilation, HVAC system, installation, utility rates and occupant behavior.
Built for residential attic retrofits.
More Consistent Comfort
May help improve temperature consistency and comfort throughout the home.
Reduced Radiant Heat Transfer
Helps reduce radiant heat transfer through the attic assembly in both hot and cold conditions.
Lower HVAC Workload
Reduced heating and cooling loads can reduce HVAC workload.
Year-Round Thermal Benefit
Designed to help manage radiant heat transfer in summer and winter.
Vapor-Permeable Construction
Micro-perforated construction lets water vapor pass through rather than be trapped.
Sheet-Form Construction
The bonded sheet-form product does not settle under its own weight after installation.

| Fire performance | ASTM E84: ≤25 flame spread; ≤50 smoke developed |
| Room burn testing | UL 1715 / UBC 26-3: PASS |
Reflective-surface performance does not mean whole-home heat transfer or energy use is reduced by 97%. Tested system R-values depend on the laboratory assembly, heat-flow direction and required air spaces. They should not be added directly to existing insulation R-values unless the installed assembly matches the tested configuration.
A supplemental layer for the attic.
Loose-laid application
Installed over existing attic-floor insulation in unfinished residential attics.
Rafter application
Installed perpendicular across rafters while maintaining appropriate ventilation, in accordance with the approved application instructions.
Install in accordance with Attiic’s current installation instructions and applicable local codes. Confirm application-specific details with Attiic before installation.
