Residential Commercial Floor Basement Wall
P1 Single Bubble Foil White
A thinner, lighter version of our foil/white reflective insulation, with a single bubble core for tight spaces where Double P1 won't fit. The foil face reflects 95% of radiant heat and blocks vapor, while the white side leaves a clean exposed finish in basements, garages, and barndominium ceilings.
Features & Benefits
What makes it work
- 5-layer bubble insulation structure
- Solid poly white surface for a clean, aesthetic finish
- Low-emittance foil surface (E=5%)
- Reflects 95% of radiant heat
- Unique LDPE plastics blend for long service life
- Stiffer than most bubbles on the market, allowing easier installation
- Suitable for all building insulation applications
- Ideal for retrofits and home improvement projects
- Excellent insulation for metal buildings and carports
- Minimizes heat bridges in metal structures
- Will not delaminate, ensuring durability and stability
- Compatible with hybrid installations using foam or fiberglass
- Ideal for metal buildings requiring a white facing
- Provides an impressive R-value when installed with an airspace

- 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.
