Residential Commercial Agriculture Wall House Wraps
RadWrap T180 REF
A house wrap that does two jobs at once: it sheds rain like a normal weather-resistive barrier, and reflects radiant heat before it ever reaches the wall cavity. It's also vapor-permeable, so any moisture inside the wall can dry to the outside. Class 1 / Class A fire-rated.
Features & Benefits
What makes it work
- Blocks bulk moisture while allowing controlled vapor release through the membrane
- High reflectivity with a low-emittance surface to cut radiant heat transfer
- Industrial-strength woven core for better tear resistance and jobsite durability
- Helps reduce condensation risk and keeps wall/roof cavities drier
- Adds a reflective layer that helps lower the effective heat load on the envelope
- Works as a breathable reflective house wrap and can also be used in attic/roof applications
- Roll format installs fast, staples cleanly, and stays stable during handling and fastening
- Fiber-free material, no itchy fibers, no special clothing or respirators needed for typical installs

Performance Data
Thermal performance
| Product name | Total R-Value (Rt) (ft2xFxh/BTU)** |
|---|---|
| T180 REF Wrap with R 15 blanket/foam | 20.71 |
| T180 REF Wrap with R 19 blanket/foam | 25.71 |
- R-values represent estimated and potential heat resistance for our insulation in the proposed application.
- Actual performance depends on air film size, temperature, surface condition, and airflow direction (up, down, or horizontal).
- Calculations are based on RIMA, AIRAH, ASHRAE, and ISO 6946 standards, following ASTM procedures for air film resistance.
- When two air spaces are used, values assume still air conditions in both spaces.
- For a full R-value assessment, please contact us directly or your nearest dealer.
