REFLECT HEAT WITH RADIANT BARRIER

Radiant barriers are typically installed in residential properties—most commonly in attics—to help reduce heat transfer during the summer months and improve indoor comfort. These systems use reflective materials such as foil, laminated roof sheathing, metal shingles, or spray-applied coatings to deflect radiant heat instead of absorbing it.
By limiting the amount of heat that enters the home through the roof, this solution can significantly lower attic temperatures, reducing peak summer heat by up to 30 degrees—often from around 150°F to approximately 110°F—helping to decrease cooling demand and energy costs.

These barriers are recommended in San Antonio due to the hot summers, especially when cooling air ducts are located in the attic. Our radiant barrier spray, similar to liquid aluminum, reduces up to 81% of the radiant heat entering the attic and does not deteriorate over time as much as other materials.

Frequently Asked Questions

Geo-Insulation is available to help with any questions regarding your needs. Below, you’ll find detailed answers to the most frequently asked questions:

There are two types available: spray-applied and foil.

The spray option is generally less costly than foil. Foil installation can take several days since the material must be fastened to the roof decking rafters, while the spray is applied directly between the rafters and is typically completed in one day. Foil systems have been known to interfere with cell phone reception, whereas the spray-applied solution does not cause this issue.

Yes. Any material odor dissipates over time and typically fades within 2–7 days.

Foil can sag and detach from the ceiling over time. Additionally, wildlife moving through the attic may damage the foil and cause it to fall onto the floor.
