When we talk about building better homes, it’s not just about what you see; it’s what you don’t see that makes all the difference. At Insight Homes, we’ve spent years perfecting the way we insulate every house we build across Delaware and parts of Maryland. Why? Because the right insulation isn’t just about energy efficiency, it’s about making a home that feels quieter, healthier and more comfortable all year round.
One of the most effective methods we use is blown-in insulation, and once you understand how it works, you’ll see why it outperforms traditional methods in many ways.
What Is Blown In Insulation (and How Does It Work)?
Blown in insulation is exactly what it sounds like, a loose-fill fiberglass insulation that’s literally blown into wall cavities and attic spaces using specialized equipment. Unlike traditional batt insulation that comes in pre-cut rolls, blown in material fills every nook and cranny sealing up the small gaps and odd corners that batts can’t reach.
Think of it like pouring sugar into a jar compared to trying to stuff in a sponge. One gives you complete coverage. The other? Not so much. That seamless coverage is what makes blown in insulation so effective at slowing heat transfer and stopping air leaks. It wraps the home in a consistent thermal barrier, helping prevent drafts, hot spots or cold patches from room to room.
Batt vs. Blown In Insulation: What’s the Difference?
Most builders still rely on rolled fiberglass batts. They’re quicker to install and less expensive upfront. But the problem is, they rarely fit perfectly. Batts leave gaps around outlets, corners, or pipes. They bunch up. They sag. And those little voids? They matter.
Blown in insulation doesn’t leave those weak spots. It’s packed densely into every inch of the wall cavity creating a solid thermal layer that works harder. And when we talk about efficiency, that’s where R-value comes in. It’s a simple equation: the better the coverage, the higher the R-value, the better the insulation performs. And blown in consistently delivers higher R-values than batts when installed with care.
The Power of R-Value: Why It Matters for Your Home
You can think of R-value like MPG for your home. The higher the number, the better your home resists heat flow, which means less energy is needed to heat or cool it.
Our walls are insulated to an R-23 and our ceilings reach up to R-49. That’s not a typo. It’s up to two and a half times more insulation than what you’ll find in many national builders’ homes. And the difference isn’t just on paper. A high R-value means more consistent indoor temperatures, fewer cycles on your HVAC system and real savings on your monthly utility bills.
It also means you don’t wake up freezing in one room while another feels like a sauna. Comfort plain and simple.
Total Comfort: Blown In Insulation as a Sound Barrier
One thing homeowners mention almost immediately after moving in is how quiet their home feels. That’s no accident.
Blown in insulation, especially when installed as a dense pack, doesn’t just block temperature changes. It absorbs sound. Street noise, barking dogs, lawn mowers even loud weather gets significantly muted. For many people, that’s an unexpected benefit that ends up being just as valuable as the energy savings.
We build for energy performance, but comfort matters, too. Peace and quiet are part of what make a house feel like home.
How We Build a Better Envelope
Every part of our insulation system is built to work together. It’s not just what’s in the walls, it’s how the entire building envelope performs as one tight unit.
We start with a sealed, conditioned crawl space to eliminate moisture and energy loss from below. We add foam sealing at every stud joint and around mechanicals to block air gaps. Then we use dense pack blown in insulation to wrap the walls and ceilings in an ultra-efficient blanket. That’s how we reach some of the highest R-values in the industry.
Every component is designed to work together to achieve the highest R ratings in the industry and that kind of coordination shows up in the way our homes feel from the moment you step inside.
Real Savings, Year After Year
Energy-efficient homes aren’t just about saving a few bucks on your utility bill. It’s about saving money every month every season for years.
Higher R-values reduce the workload on your HVAC system. That means fewer repairs, longer lifespan and lower energy use—especially during the intense heat of summer or deep cold snaps in winter. When insulation is done right, the savings don’t just add up—they compound over time.
So whether you’re running the A/C in August or heating your home through a Delaware snowstorm, your home stays comfortable without sending your utility bill through the roof.
Frequently Asked Questions About Blown In Insulation
Is Blown In insulation safe?
Yes. We use formaldehyde-free fiberglass insulation that’s safe for indoor air quality and completely non-toxic.
Can I upgrade insulation in an older home to Blown In?
Technically yes, but it’s much more efficient to install during the building process. Retrofitting blown in insulation means opening up existing walls which can be invasive and costly.
Does Blown In insulation settle over time?
Not when it’s done right. Our dense-pack method ensures the material stays in place and retains its insulating power for decades.
Is Blown In insulation good for all seasons?
Absolutely. It keeps the heat out during summer and traps warmth in during winter giving you year-round temperature consistency and comfort.
Built Smarter from the Inside Out
When you choose to build with us, you’re not just getting a beautiful home, you’re getting smarter construction from top to bottom. From the conditioned crawl space to the R-50 ceiling insulation, every layer has been carefully designed to create a home that’s more comfortable, more efficient and simply better to live in.
Blown in insulation is just one example of how we go beyond the standard to give you a home that’s built to perform and built to last.
