Reflective Bubble Reflective insulation: 1 layer of 5/32" polyethylene bubble that is sandwiched between two metalized, low emissivity surfaces. The polyethylene encapsulated air bubbles serve as an effective thermal break as well as a vapor barrier while the two outer metalized surfaces reflect up to 96% of all radiant energy.

How It Works
Single Bubble Reflective Insulation reduces heat transfer by reflecting radiant energy instead of absorbing it. The bubble core adds a layer of thermal resistance and a small air space that enhances overall performance. This dual-action design makes it an excellent choice for climates requiring both heating and cooling solutions.
Installation Tips
To optimize performance, incorporate an inch or more airspace between the insulation and the outer surface of structure.
Seal the seams with reflective tape.

Benefits of Single Bubble Reflective Insulation
Enhanced Energy Efficiency
Reflects Up to 97% of Radiant Heat
The reflective foil layers significantly reduce radiant heat transfer, keeping indoor spaces cooler in summer and warmer in winter. This directly reduces the demand on heating and cooling systems.
Lower Utility Bills
By improving thermal performance, single bubble insulation helps cut monthly energy costs. It’s an effective solution for both homeowners and businesses looking to boost efficiency affordably.
All-Season Indoor Comfort
Temperature Regulation
Maintains a more stable indoor climate by minimizing heat loss in winter and heat gain in summer. Ideal for improving comfort in garages, sheds, warehouses, and homes alike.
Consistent Thermal Barrier
The bubble core offers added resistance to conductive heat transfer, further enhancing overall insulation value—especially in climates with extreme temperature variations.
Moisture and Vapor Control
Reduces Condensation
Acts as a vapor barrier, helping to minimize condensation in crawl spaces, basements, and metal buildings. This reduces the risk of mold, mildew, and structural damage.
