Radiant Barrier Installed Before Attic Insulation

What Is An Attic Radiant Barrier?

An attic radiant barrier is a highly reflective material that is installed on the plywood or draped over trusses under the roof decking in the attic. It helps reflect thermal radiation and reduce heat transfer from entering the attic.

Frequently Asked Questions

How does an attic radiant barrier work?

Radiant barriers reflect radiant heat instead of absorbing it, which helps lower attic temperatures and reduces the strain on your cooling system.

Is this a replacement for attic insulation?

No. A radiant barrier is not a substitute for insulation. It’s an added layer of protection that works alongside your existing insulation and ventilation to better regulate attic airflow and temperature.

How long does an installation take?

Most installations are completed in a single day, depending on the attic’s size, accessibility, and whether additional work is being done at the same time.

Does a radiant barrier installation come with a warranty?

Yes, our radiant barrier installation is backed by a 10 year warranty on both the materials and our installation workmanship. Should any issues arise due to defective materials or improper installation, we will repair or place the affected radiant barrier at no additional cost to you during this 10 year period.
