What is AtticFoil Radiant Barrier?
AtticFoil is a professional-grade radiant barrier made from double-sided pure aluminum foil laminated to a tear-proof, reinforced material. It reflects up to 97% of radiant heat away from your home, keeping your attic cooler in summer and reducing energy costs.
How does a radiant barrier 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. AtticFoil reflects up to 97% of this heat back, preventing it from warming the insulation and air in your attic.
How much can I save with AtticFoil?
Most homeowners see 10-15% savings on cooling costs after installing AtticFoil. By reflecting 97% of radiant heat and lowering attic temperatures by up to 30 degrees Fahrenheit, your air conditioning system works significantly less.
Does AtticFoil work in winter too?
Yes! AtticFoil is double-sided, so in winter it reflects warmth back into your home, reducing heating costs as well. It provides year-round energy savings.
Will AtticFoil interfere with my WiFi or cell phone signal?
AtticFoil is perforated to allow breathability, which significantly reduces any potential for signal interference. Most customers report no issues with WiFi, cell phones, or other wireless devices.
How long does AtticFoil last?
AtticFoil is extremely durable and designed to last for decades. The heavy-duty tear-resistant construction ensures it won't degrade, rip, or lose effectiveness over time like some products.
Can I install insulation over AtticFoil?
AtticFoil works best when it faces an air space. We typically install it on the underside of your roof rafters, allowing it to reflect heat before it reaches your insulation. This makes your existing insulation work 50-100% more effectively.
How long does installation take?
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.
Do I still need attic insulation if I have AtticFoil?
Yes! AtticFoil and traditional insulation work together for maximum energy efficiency. Radiant barriers reflect heat, while insulation slows heat transfer. Combined, they create the most effective energy-saving system available.
Is attic ventilation still important with AtticFoil?
Absolutely! Proper attic ventilation works hand-in-hand with radiant barriers. While AtticFoil controls radiant heat, good ventilation helps control convection loads. Together they maximize comfort and energy savings.
