Radiant Barrier | Energy Efficiency

Along with comfort and convenience, today’s homeowners are looking for a way to save money. Offering them an opportunity to lower their energy bills and feel more at-ease within their homes will, in turn, prove to be a benefit to builders.

That’s the purpose of Fi-Foil’s attic radiant barriers…and it’s why our solutions reflect on you.

The attic is the perfect place for Fi-Foil’s radiant barrier systems: First, because the roof is the surface most exposed to solar radiation, and second, because most of the solar gain absorbed by the roof is transmitted down to the attic floor by radiation. Since the attic airspace separates the hot roof surface from the ceiling, no heat will move down by conduction, and the heat will not convect down from the hot roof to the ceiling because heated air rises. If you place an attic radiant barrier in the airspace between the hot roof deck and the cooler attic floor, you can eliminate almost all radiant heat transfer.

1. Solar radiation causes roof temperatures to reach 160˚F to 190˚F.
2. Heat is conducted through roofing materials and radiated to the ceiling below.
3. Attic temperatures climb to superheated levels, typically 140˚F in the summer.
4. Ceiling insulation R-values are rated at 75˚F and 50% relative humidity. As temperatures and humidity levels increase, R-values diminish. Radiant heat transfers into air conditioning ducts increasing energy costs. Attic structure and contents saturate and continue to transfer heat even after the sun has set.
5. Comfort is compromised – A/C run time increases and, in peak loads, cannot maintain internal temperature set points.
6. Air quality is compromised – hot humid air is drawn through leaks in the duct system.

The Solution - Silver Shield™ Attic Radiant Barrier

1. Reduces radiant heat transfer up to 97%. Treats the problem at its source - the roof.
2. A/C savings up to 12%. Significantly reduces attic temperatures up to 30°F.
3. Increases insulation and air conditioning duct efficiency.
4. Lowers temperatures and improves comfort in areas that are not typically air conditioned, such as garages and lanais.
5. Qualifies for Florida Energy Code Credits.
6. Energy Star Rating helps to qualify for energy efficient mortgages.
