We cut heating and cooling bills up to 30%, quiet winter wind and summer storm noise, and back every install with a 90-day performance guarantee.
In Indiana, where freezing winters and humid summers push HVAC systems hard year-round. Attics across the region can hit 130°F in July and fall below freezing in January — and without proper blown-in insulation, that heat and cold move straight through the ceiling, driving up energy bills and straining HVAC equipment.
Our Indiana crews install premium blown-in fiberglass to a verified R-value blanket that stops winter heat loss, blocks summer heat gain, preserves attic ventilation, and dampens winter wind howling and summer storm noise. Most homes are completed in a single day, backed by a 90-day guarantee.
The chart below compares monthly heating and cooling costs for a typical Central Indiana home — one with old or under-insulated attics, and one upgraded with InsulX blown-in fiberglass to R-49. The biggest gaps show up exactly when you need relief most: deep winter and peak summer.

The U.S. Department of Energy recommends R-49 to R-60 for Indiana attics (Insulation Zone 5). Most Central Indiana homes benefit most from R-49, which we install to a verified depth and document with a depth card for every customer.
Yes. Properly installed blown-in insulation typically cuts Indiana heating and cooling bills 15–30% by stopping attic heat loss in winter and attic heat gain in summer. On a $250/month energy bill, that's $37–$75 kept every month. Most homeowners recover the investment in 3–5 years.
We inspect and prep the attic, seal obvious air leaks around penetrations, protect the living space, then blow fiberglass to a verified target depth. We finish with a depth card photo documenting the installed R-value and a full cleanup. No demolition, no structural changes — most homes are done in a single day.
Absolutely. Blown-in fiberglass is non-combustible, won't hold moisture, and preserves attic ventilation paths — critical for managing both winter condensation and summer humidity. It fills gaps and voids that batts miss, which is essential for stopping winter heat loss through the ceiling.
In the Indianapolis metro, blown-in fiberglass insulation typically costs $1.50–$3.50 per square foot installed, or roughly $1,200–$3,500 for an average attic depending on existing insulation, access, and target R-value. InsulX provides a free instant estimate before any work begins.
