Radiant Barrier Insulation in Indianapolis, Carmel, Fishers & Zionsville

When the sun beats down on your roof in summer, attic temperatures can soar to 120–140°F or higher. Even the best conventional insulation slows heat transfer — but radiant barrier insulation reflects it before it enters your attic.

We specialize in radiant barrier attic installations across Indianapolis, Carmel, Fishers, and Zionsville, helping homeowners lower cooling costs, extend roof life, and create more comfortable living spaces.

Why Radiant Barrier Insulation?

Reflects radiant heat

Blocks up to 95–97% of radiant energy, unlike fiberglass or cellulose which only resist conductive heat.

Keeps attics cooler

Can lower attic temps by 20–30°F, reducing load on your AC system.

Improves comfort in living spaces

Especially noticeable in rooms directly below the attic, like upstairs bedrooms and bonus rooms.

Pairs well with other insulation

Works alongside batt, blown-in, or spray foam for a complete envelope solution.

Great ROI in hot summers

Indiana’s combination of humid summers and cold winters makes radiant barriers an effective add-on.

Durable & lightweight

Aluminum foil or foil-laminated material resists moisture, pests, and degradation.

Our Radiant Barrier Installation Process

01

Attic inspection

We check existing insulation, ventilation, and framing.

02

Material selection

Choose between foil-faced sheeting, multi-layer reflective, or spray-applied barriers depending on attic design.

03

Installation

Barrier is attached to rafters, roof deck, or laid over existing insulation for maximum reflection.

04

Airflow optimization

Ensure soffit and ridge vents stay clear so your attic continues to “breathe.”

05

Final check

We verify coverage, ventilation clearance, and overall performance.

Local Use Cases

Types of Radiant Barrier Systems

TYPE

DESCRIPTION

BEST USE CASE

Foil Sheet (Stapled)

Aluminum foil attached to roof rafters

Most common, great for attics with open framing

Foil Laminated Board

Rigid panels with foil face

Adds structure, works with cathedral ceilings

Spray-Applied Barrier

Liquid coating with reflective particles

Hard-to-reach attics, retrofit applications

Multi-Layer Reflective

Foil + bubble or foam layers

Adds radiant + conductive resistance

Cost & ROI

Radiant barriers are generally more affordable than spray foam, and often installed as an add-on during insulation upgrades.

ROI comes in the form of reduced cooling bills, longer HVAC lifespan, and improved home comfort.

Many homeowners see payback in 3–5 years, especially in multi-story homes with hot upper levels.
