What Attic Insulation Actually Does
Attic insulation slows down heat movement. In winter, it keeps warm air from escaping through your ceiling. In summer, it blocks heat from radiating down into your living spaces. The result? Your furnace and AC don't have to work as hard, rooms feel more comfortable, and energy bills drop.
Here's what matters before insulation goes in: sealing the big air leaks. Gaps around plumbing pipes, electrical chases, recessed lights, and attic hatches let conditioned air escape even when insulation is present. The Department of Energy recommends sealing those openings first, then adding insulation on top. It's like putting on a jacket over a shirt with holes—seal the holes, then layer up.
Most homeowners notice three things after installation:
Why Choose Integrity for Attic Insulation
We've completed attic insulation projects for over 10,000 customers across Southeast Michigan and Northwest Ohio. Our approach stays straightforward: seal the leaks that matter, match insulation material and depth to your home's needs, and keep your living spaces clean during the work.
What sets our attic insulation services apart:
What We Install in Attics
We install blown-in insulation for most residential attics. The material gets blown through a hose into your attic space, where it settles around joists, odd angles, and hard-to-reach corners. Unlike batt insulation (the pink rolls you see at hardware stores), blown-in material conforms to irregular spaces and doesn't leave gaps where air can sneak through.
Why blown-in works well:
Ventilation stays balanced: Your attic needs airflow to manage moisture and prevent ice dams in winter. We make sure insulation doesn't block soffit vents or ridge vents during installation. Proper ventilation + proper insulation = a system that performs without causing problems down the line.
For details on material options, coverage rates, and how blown-in compares to other types, see our Blown-In Insulation page
Our Attic Insulation Process
Check Current Conditions
We start by looking at what's already in your attic. If you can see the tops of your floor joists, insulation depth is probably below recommended levels. We also check for obvious air leaks—gaps around pipes, wiring penetrations, recessed lights, and the attic hatch. These are the spots where air moves freely between your living space and the attic.
Seal the Big Gaps First
Before insulation goes in, we seal large openings. That means sealing around plumbing chases, HVAC ducts, electrical boxes, and any place where conditioned air can escape. The EPA and Department of Energy both emphasize this step—sealing leaks first makes the insulation work better and prevents you from just insulating over pathways where air still moves.
Prep, Protect, and Install
We cover areas that need protection (like stored items or walkways), set up our blowing equipment, and start filling the attic to target depth. The material distributes evenly around obstacles and settles into place. Installation typically wraps up in a few hours for most homes, depending on attic size and access.
Light Cleanup and Walkthrough
After installation, we do a quick cleanup and walk through what we did. You'll see the difference in insulation depth right away. We also provide basic maintenance tips (don't compress insulation with storage, keep vents clear) and answer any questions before we leave.
