When your attic needs more insulation, the brand matters. Owens Corning has been making fiberglass insulation for decades, and there's a reason contractors keep using it. The loose material fills around joists, pipes, and wiring without leaving gaps—you get coverage everywhere, not just the easy-to-reach spots.

Better insulation means fewer cold spots in winter, less heat creeping through in summer, and lower energy bills month after month. The material settles into place evenly across your entire attic floor. That even coverage is what makes the difference between an insulation job that performs and one that leaves you wondering why your bills didn't change.

We've been installing attic insulation for over 25 years in Ohio and 3 years in Michigan. When homeowners ask us which brand to use, we recommend Owens Corning. The material performs consistently, coverage stays even, and Owens Corning backs their product. You're not taking a chance on an unknown manufacturer.

Adding insulation without sealing air leaks first is like putting on a winter coat but leaving your windows open. You'll still be cold, and you'll wonder why the insulation didn't help as much as you expected.

Before we blow any insulation, we seal major openings where air is leaking between your living space and the attic.

Here's what happens when we install Owens Corning attic insulation at your home.
 
1. Check current depth and obvious leaks
We measure how much insulation you already have and look for air leaks that need sealing. If your attic is easy to access and we don't see major issues, this takes about 30 minutes. If we find problems—rotted wood under the roof, gaps around fixtures, or water stains that suggest a leak—we'll document them and talk through what needs fixing before insulation goes in.
 
2. Seal first, prep and protect
We seal the major air leaks we identified. Then we prep your home. The blowing machine stays outside, but the hose runs into your attic. We protect your living spaces with drop cloths and make sure the hose path is secure. This keeps dust and debris out of your rooms.
 
3. Blow Owens Corning fiberglass to planned depth for even coverage
The machine feeds compressed Owens Corning fiberglass through the hose into your attic. We work systematically across the attic floor, building up the insulation to the planned depth. The material fills around obstacles and settles into an even layer. We check coverage as we go to make sure there are no thin spots or gaps.
 
4. Light cleanup and walkthrough
When the insulation is in place, we clean up any stray material and do a final walkthrough with you. You'll see the new insulation coverage, and we'll answer any questions about what we did. Most installations take a few hours from start to finish, depending on attic size and access.

For a more detailed breakdown of what happens during an attic insulation project, see our attic insulation process page:

Insulation works best when your attic can breathe. That means keeping the vents along your roof edges (soffits) and at the peak (ridge vents) clear so air can move through the attic space. The living space below stays sealed and conditioned. The attic stays vented so moisture doesn't build up.

When we install Owens Corning insulation, we make sure not to block soffit vents. If insulation covers those vents, air can't enter the attic, and you end up trapping moisture. Over time, trapped moisture leads to mold, rot, and reduced insulation performance.

Attic insulation is an investment that pays off over time through lower energy bills and better comfort. We offer monthly payment plans that make it easier to fit the project into your budget. Most approvals happen within 24 hours.

If you want to estimate your project cost before talking to us, use our attic insulation cost calculator. It gives you a ballpark range based on your attic size and current insulation level. Then explore financing options to see how monthly payments might look.
