Reflective Bubble Reflective: 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 97% of all radiant energy.
Reflective Bubble Reflective - A Single Bubble Insulation
Overview
Single Bubble Reflective Insulation is a highly effective, lightweight solution for thermal insulation and radiant heat protection. Engineered with a core layer of polyethylene air bubbles, sandwiched between two layers of reflective aluminum foil, it acts as an efficient barrier to radiant heat transfer. Ideal for both residential and commercial applications, this versatile insulation provides superior energy savings, comfort, and protection against moisture.

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.

Applications of Single Bubble Reflective Insulation
Residential Applications
Attics
Single Bubble Reflective Insulation is ideal for attic spaces, where it reflects radiant heat in the summer and retains warmth in the winter. Install it over joists, under rafters, or along attic walls to increase energy efficiency and comfort.
Walls
Perfect for both retrofit and new construction, this insulation enhances thermal performance in exterior and interior walls. It helps maintain consistent indoor temperatures by reducing radiant heat gain or loss.
Floors and Crawl Spaces
When placed beneath floors or between joists, it acts as both a thermal and moisture barrier. This is especially useful in homes with crawl spaces, helping to reduce drafts and protect against dampness.
Garages and Workshops
Apply to garage walls, ceilings, or doors to reduce energy loss and create a more stable indoor temperature—ideal for both personal workspaces and storage use.
Commercial and Industrial Applications
Metal Buildings and Warehouses
Metal structures are prone to heat absorption and loss. Reflective insulation moderates indoor conditions by reflecting radiant energy and reducing thermal transfer through the building envelope.
Storage Facilities
Insulation helps keep internal environments stable for stored goods, preventing damage from heat and moisture fluctuations. Useful in both conditioned and unconditioned storage areas.
Agricultural Buildings
Protects livestock, feed, and equipment from temperature extremes. Often used in poultry houses, barns, and dairy facilities where ventilation and thermal regulation are key.
Specialty and Alternative Uses
Recreational Vehicles (RVs) and Campers
Enhances comfort and energy efficiency in RVs and campers by lining walls, ceilings, and floors. Lightweight and flexible, it’s ideal for mobile applications where space and insulation matter.
Tiny Homes and Shipping Containers
Its compact thickness and strong performance make it a perfect fit for tiny homes and container homes. Easily integrated into walls, ceilings, and floors for maximum space efficiency.
HVAC Duct and Water Heater Wraps
A popular DIY use—wrapping ducts and water heaters with reflective insulation improves energy efficiency and reduces standby heat loss.
Greenhouses
Helps regulate internal greenhouse temperatures by reflecting excess radiant heat while maintaining light diffusion. Especially beneficial for delicate plant environments.
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.
Helps Prevent Moisture Damage
Protects wood, drywall, and stored goods from moisture-related deterioration by limiting water vapor infiltration from external sources or ground-level humidity.
Durable and Maintenance-Free
Long Lifespan
Resistant to tearing and corrosion. Maintains its performance over time without the sagging or breakdown that can occur with traditional insulation materials.
Minimal Upkeep
Once installed, it requires little to no maintenance. It retains its insulating and reflective properties without the need for frequent inspections or replacements.
Easy Installation
Lightweight and Flexible
Can be installed quickly using basic tools. The flexibility allows it to wrap around pipes, fit into tight spaces, and conform to irregular shapes with ease.
Versatile Application Methods
Compatible with a variety of fastening methods—staples, adhesives, or mechanical fasteners—making it suitable for DIY projects or professional installation.
Cost-Effective Investment
Affordable Upfront Cost
Compared to some bulkier insulation materials, single bubble reflective insulation offers a lower purchase price while delivering competitive thermal performance.
Long-Term Value
Its energy-saving benefits and durability lead to a strong return on investment. Reduces HVAC system wear and can extend the life of building components.
Eco-Friendly Performance
Reduces Carbon Footprint
By lowering heating and cooling energy demands, this insulation helps reduce greenhouse gas emissions from energy production.
Recyclable and Safe
Many products are made from recyclable materials and are free from harmful fibers or chemicals—making them safer to handle and better for the environment.
