Blown-In Insulation: Is it Right for Your Home?

If you have a sneaking suspicion your home may need more insulation, you’re probably right. High energy bills, chilly drafts, walls that are cool to the touch and uneven temperatures from room to room are just some of the signs that your house could benefit from an insulation upgrade. 

Not sure what kind of insulation will fix your problem? You’re not alone. Types of insulation vary, depending on where it’s being installed. From traditional fiberglass batt to popular spray foam, our team installs it all. But here in the Chicago suburbs, the most common choice is blown-in insulation. 

What is Blown-In Insulation? 

So what exactly is blown-in insulation? Also known as loose-fill, it’s a material that’s literally blown in, and fills the space that requires insulation. Imagine filling your walls up with down feathers, and you’re on the right track. 

While filling walls with down feathers might sound warm and cozy, we promise choosing loose-fill cellulose insulation is a much better idea. This eco-friendly insulation is our go-to choice here at Koala Chicago. It’s made from wood-based materials, like recycled cardboard and newspaper, and is treated to resist mildew and fire too.  

Cellulose insulation is vacuum-packed tight into cubes but is loose and fluffy as a cloud once installed. An awesome option for so many reasons, blown-in insulation is the material we find ourselves recommending again and again.  

Where is Blow-In Insulation Best Used?

Blow-in insulation is a great choice for two types of projects: 

1. Insulating Attic Spaces 

If you have an unfinished attic, cellulose insulation is a perfect choice. Why? First, it’s cheaper than spray foam but still has a high R-value. Second – it holds up over time, retaining its ability to insulate even as it slowly settles. And third – installation is quick.  

2. Insulating Existing Walls or Ceilings

Insulating an existing wall or ceiling might feel impossible, but a seasoned installer with the right equipment can do the job pretty painlessly. 

How is Blown-In Insulation Installed?  

In an Attic Space 

Installing blown-in insulation in an attic is best left to professionals, as it requires special equipment to get the job done right. 

First, any existing insulation that might be damaged is removed by high-powered vacuums. Next, fresh cellulose is blown in using a blower hose. The installers will fill every nook and cranny, including the space between floor joists. It can even be layered over existing batt insulation. 

How deep should the insulation in your attic be? It all depends on your climate and desired R-value. Scheduling a free evaluation by a professional is the best way to know if your attic is adequately insulated. 

In Existing Walls or Ceiling

It’s not uncommon for houses – even new-construction homes – to need insulation added to walls or ceilings. Often homeowners think it’ll be impossible, or very costly, to add insulation into closed spaces. But, it’s actually quite simple! 

Whenever possible, our team at Koala in Chicago likes to install blown-in insulation into walls from the exterior. This is easy if a home is sided; we simply pop off a piece of siding, drill a hole and use our blower to fill the space with insulation. 

It is possible to do this from an interior wall or ceiling too, it just involves wall patching and paint after the job is complete. 

Why Choose Blown-In Insulation? 

There are many reasons blown-in insulation is the most recommended option here in Chicago: 

1. It’s Affordable 

Having blown-in insulation installed in your attic or walls is an affordable home improvement that pays off. Not only will your home be cozier, quieter, and more comfortable, but its value will increase. 

2. New Insulation Pays for Itself 

Over time, properly insulating your home pays for itself through lower heating and cooling bills. Adding insulation can reduce your energy bills by 30% or more. 

3. It’s Environmentally Friendly

Cellulose insulation is made of 85% recycled materials, making it a green option that doesn’t compromise performance. 

4. Installation is Fast 

Hire a professional with the right equipment, and the job can be done quickly! Most installation jobs can be completed in a day, making this one home improvement that you can check off your list in a snap.
