What Is Infrastop Double Bubble Insulation
Infrastop Double Bubble Insulation is a reflective, two-layer energy barrier designed to reduce heat transfer through roofs, walls, and floors. The product combines a foil-faced inner layer with a spaced air gap and a second reflective surface to minimize radiant heat transfer. Commonly used in residential and commercial projects, it provides a lightweight, easy-to-handle solution that complements other insulation types. For homeowners seeking improved comfort and lower energy bills, double bubble insulation delivers a practical option that is compatible with various building envelopes.
How Double Bubble Insulation Works
The core principle is radiation reflection coupled with a trapped air cavity. The first foil layer reflects radiant heat away from living spaces, while the air gap reduces conductive and convective heat transfer. A second foil surface further reflects heat back toward its source, creating a low-emissivity barrier. This combination boosts thermal resistance across a wide temperature range and performs well in hot summers and cold winters. The result is a noticeable reduction in cooling and heating loads when properly installed.
Key Benefits For U.S. Homes
- Energy Efficiency: Reduces cooling costs in summer and heating costs in winter by limiting radiant heat transfer.
- Lightweight And Flexible: Easy to handle, cut, and install in tight spaces such as attic joists and crawl spaces.
- Moisture Resistance: Foil facings help manage humidity and minimize mold risk when combined with proper ventilation.
- Versatility: Suitable for roofs, walls, and floors, and works well with radiant floor systems and existing insulation.
- Cost-Effective: Lower installation time and material costs compared to some thicker insulation options, with potential long-term energy savings.
R-Value And Performance
Double bubble insulation typically provides an R-value that depends on thickness, installation method, and surrounding materials. While foil-faced reflective products may not carry a high R-value on their own, they significantly reduce heat gain and loss when combined with an existing insulation layer, air sealing, and proper ventilation. In hot climates, the radiant barrier effect can yield substantial savings during peak sun exposure. For the American homeowner, the practical benefit hinges on local climate, attic ventilation, and the presence of continuous insulation layers.
Installation And Tips
Proper installation is critical to maximize performance. Key steps include sealing all gaps, ensuring full contact with the surface, and avoiding compression of the material. Inattentive installations can create air gaps that diminish effectiveness. When used in attics, place the double bubble insulation on the warm side of the roof deck in hot climates, or beneath the roof deck if a vented roof is desired. In walls, maintain an unobstructed air gap to preserve radiant barrier effectiveness. Always follow the manufacturer’s guidelines for overlaps, tape, and fasteners to ensure a continuous reflective barrier.

Applications And Uses
The product is widely used in residential renovations, new construction, and light commercial projects. Inattic conversions, cathedral ceilings, and retrofits in older homes are common scenarios where double bubble insulation contributes to a balanced thermal envelope. In coastal or humid regions, the moisture-resistance aspect supports durability when combined with appropriate ventilation. For retrofit projects, it can be paired with traditional batt insulation to optimize overall performance without dramatically increasing wall thickness.
Maintenance And Longevity
Double bubble insulation is generally low maintenance. It does not require painting or coatings and can last decades if not damaged by punctures or improper handling. Inspect installations during seasonal repairs or after severe weather for signs of moisture intrusion or tears in the foil facing. If needed, small tears can be sealed with approved reflective tape. Avoid stepping on or compressing the material, which can reduce reflective efficiency and air gap integrity.
Comparisons With Other Insulation Types
Compared with fiberglass or mineral wool, double bubble insulation emphasizes radiant heat reflection more than bulk insulation. While bulk insulations provide higher R-values per inch, reflective barriers excel in hot climates by reducing heat gain through radiation. In energy retrofit scenarios, many builders pair double bubble with traditional insulation to create a balanced system. When evaluating cost, consider not only material price but also potential savings from reduced cooling loads and faster installation times.
Cost Considerations And ROI
Prices for double bubble insulation vary by brand, thickness, and sheet size. For most residential projects, cost-effectiveness improves with improved attic access, fewer air leaks, and the avoidance of unnecessary thick insulation where a radiant barrier suffices. A practical ROI analysis should include anticipated energy savings, climate-specific performance, and the costs of labor and accessories. In regions with intense summer heat, homeowners may see quicker payback due to lower air conditioning demand, while in milder climates the ROI may be more gradual.
Frequently Asked Questions
Q: Can Infrastop Double Bubble Insulation be used in walls? A: Yes, it can be installed in walls where appropriate air gaps are maintained and when combined with other wall insulation. Q: Is it suitable for humid environments? A: It can help manage radiant heat and moisture if used with proper ventilation and a complete building envelope strategy.
