AtticFoil is a heavy-duty, pure aluminum radiant barrier that reflects 97% of radiant heat away from your home. Lower attic temperatures by up to 30°F and reduce cooling costs by 10-15%!
AtticFoil is a professional-grade radiant barrier made from double-sided pure aluminum foil laminated to a tear-proof, reinforced material. Unlike traditional insulation that slows heat transfer, AtticFoil reflects radiant heat away before it can enter your living space, keeping your home cooler in summer and warmer in winter.
When your attic heats up, it's not just from outside air temperature—it's the invisible radiant heat from the sun penetrating your roof. AtticFoil acts like a shield, reflecting up to 97% of this radiant energy back toward its source. The result? A dramatically cooler attic that means less work for your air conditioner and lower energy bills year-round.
How Radiant Barriers Work
Unlike traditional insulation that slows heat transfer, radiant barriers reflect heat away before it enters your living space. When the sun heats your roof, that heat radiates down into your attic. A radiant barrier reflects this heat back, preventing it from warming the insulation and air in your attic.
Proven Temperature Reduction
Independent testing shows AtticFoil can lower attic temperatures by up to 30 degrees Fahrenheit on hot summer days. By reflecting 97% of radiant heat before it enters your attic, your air conditioning system works significantly less, resulting in 10-15% savings on cooling costs and improved year-round comfort.
What Makes AtticFoil Different?
Not all radiant barriers are created equal. AtticFoil stands out as the professional choice for maximum performance:
Does it really work? Absolutely! AtticFoil reflects up to 97% of radiant heat transfer, and when combined with proper insulation, creates one of the most effective energy-saving systems available. Every home is different, so we'll assess your specific situation to project your expected savings.
Key Benefits of AtticFoil Radiant Barriers
97% Heat Reflection: Pure aluminum reflects nearly all radiant heat before it enters your attic
Year-Round Savings: Blocks heat in summer, reflects warmth back in winter—lowers both cooling AND heating costs
Prevents Moisture Problems: Perforated design allows air flow, preventing condensation and mold growth
Durable & Long-Lasting: Heavy-duty tear-proof construction lasts for decades without degrading
Fast Installation: Retrofit existing attics quickly—typical installations complete in one day
Boosts Insulation Performance: Makes your existing insulation work 50-100% more effectively
Cleaner, Cooler Attic: Lower attic temperatures mean less dust circulation and better HVAC performance
Environmentally Friendly: Reduce your carbon footprint while saving money on energy bills
AtticFoil is one of the most cost-effective energy upgrades you can make. By stopping radiant heat at the source—your roof deck—you prevent the #1 cause of high attic temperatures. Combined with adequate insulation, AtticFoil creates a complete thermal barrier that can save 10-15% on cooling costs while dramatically improving home comfort.
Professional AtticFoil Installation
AtticFoil can be installed in two primary ways, depending on your attic configuration and goals. We'll recommend the best method for your specific situation:
Installation Method #1: Stapled to Roof Rafters
The most common and effective method for maximum heat reflection:
- Attic Assessment: We measure your attic space and identify the optimal installation pattern
- Rafter Installation: AtticFoil is stapled to the underside of your roof rafters, creating an air gap between the foil and roof deck
- Complete Coverage: All sections are properly overlapped and secured for maximum effectiveness
- Quality Inspection: Final walkthrough ensures proper installation and no gaps in coverage
Installation Method #2: Laid Over Insulation
Alternative method when rafter access is limited:
- Insulation Check: We inspect your existing attic insulation condition
- Foil Application: AtticFoil is carefully laid on top of existing insulation with foil facing up toward the roof
- Seam Sealing: Overlapping seams are secured for continuous coverage
- Final Review: Complete inspection ensures proper placement and maximum benefit
Installation Time: Most residential attic installations are completed in a single day with minimal disruption to your daily routine. We work efficiently and clean up thoroughly when finished.
Ideal Applications
Residential Homes
Perfect for existing homes where adding more insulation is difficult or impractical.
Attics with Low Clearance
Works excellently in confined attic spaces where foil installation would be challenging.
Metal Buildings
Excellent for warehouses, workshops, and commercial metal structures.
Bonus Rooms
Keep bonus rooms and upstairs spaces comfortable year-round.
Maximize Your Energy Savings
While radiant barriers are highly effective, they work even better when combined with other energy-efficiency improvements:
Add Attic Insulation: Radiant barriers reduce heat transfer at about 50%, while insulation accounts for the other 50% of energy efficiency. Learn about our attic insulation services
Seal Air Leaks: Proper air sealing prevents conditioned air from escaping and reduces energy waste
Adequate Ventilation: Proper attic ventilation works with radiant barriers to keep your attic cooler
Remember: Attic insulation is the most important at about 50% of the insulation value of the home. Crawl spaces are 2nd at about 30%, and walls are last at about 20%. Installing good windows and doors is more important than trying to insulate the walls.
