Residential Commercial Agriculture Attic Floor Metal Building
Double P2 Double Bubble Double Foil
Our most versatile reflective insulation, with foil faces on both sides and a thick double-bubble core for stronger thermal performance than single-bubble products. It reflects 95% of radiant heat, blocks vapor, and works in walls, floors, attics, and metal buildings. Use it anywhere you want both faces reflecting heat back where it came from.
Features & Benefits
What makes it work
- 7-layer bubble insulation structure for superior strength and performance
- Low-emittance foil surfaces (E=5%)
- Reflects up to 95% of radiant heat
- Unique LDPE plastic blend for extended service life
- Stiffer and more durable than most bubble insulation products on the market
- Easy to install and suitable for all building insulation applications
- Ideal for retrofits and home improvement projects
- Excellent insulation solution for metal buildings and carports
- Helps reduce thermal bridging in metal structures
- Delivers strong R-values when installed with air spaces
- Will not delaminate over time
- Enhanced durability and long-term stability
- Compatible with hybrid installations using foam or fiberglass

Thermal performance
| Assembly | Heat-Flow Direction | Typical R-Value |
|---|---|---|
| Attic - Vented | Heat flow down | Call or e-mail for R-Value |
| Metal Buildings | Heat flow down | R-9.7 to R-22.5* |
| Metal Buildings | Wall | R-5.0 to R-9.0* |
| Post Frame Buildings | Heat flow down | R-9.7 to R-22.5* |
| Radiant Floors | Heat flow down | R-9.7 to R-22.5* |
| Wall - Basement Masonry | Wall | R-5.0 to R-9.0* |
- 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.
