A radiant barrier is a shiny, reflective material, typically made of aluminum foil, that is used to reduce heat transfer. It is most commonly installed in the attic to reflect radiant heat away from the livings spaces below.
Xtreme® reflective attic insulation barrier:
Radiant barriers are not created equally. Today’s marketplace offers many different manufacturers with a wide variety of quality.
Based on knowledge gained from 15+ years in the reflective insulation marketplace, we’ve designed all our reflective products using the highest quality raw materials, manufacturing processes, and lamination machinery available in order to exceed ASTM testing requirements for performance and safety.
Radiant barrier insulation is often installed in attics, either stapled to the roof rafters or directly to the roof decking. The temperature in the attic can be reduced by up to 30 degrees in summer months when enclosing it with an attic foil.
We don't recommend installing radiant barriers over the attic floor. If you must, make sure there is sufficient air flow in the attic. This will help prevent condensation from forming under the radiant barrier on the attic floor. Also, over time, dust accumulation can decrease the effectiveness of a radiant barrier placed on the attic floor.
