Why Insulate Your Attic?
Let’s face it – Insulation an attic right now is probably acting like a heat sponge in summer and a cold air vacuum in winter. If your energy bills are creeping higher than a Dallas Cowboys fan’s hopes in preseason (only to crash later), poor insulation might be the culprit. Attic insulation isn’t just a bunch of fluffy stuff we toss up there. It’s the superhero cape your house deserves – slashing energy costs, stabilizing indoor temps, and even boosting home value. Your HVAC will thank you. Your wallet will high-five you. And your family won’t complain about their bedrooms feeling like an igloo or a sauna anymore.
How Attic Insulation Works
Heat flows one way: from warm areas to cooler ones. In the summer, that means outdoor heat is crawling in; in winter, indoor heat is escaping. Insulation creates a thermal resistance (measured in R-value) to stop this back-and-forth nonsense. The higher the R-value, the better the heat-stopping power. R is for “resistance”… not “ridiculously hot attic.”
Signs Your Attic Needs Better Insulation
Your utility bill makes you audibly gasp
Upstairs rooms feel like a punishment
Your HVAC runs harder than a Buc-ee’s on Memorial Day
You see ice dams (in winter) or condensation (in summer)
Old insulation looks like something a possum dragged in
TYPES OF ATTIC INSULATION
Fiberglass Insulation (Batts vs. Loose-Fill)
Fiberglass is that pink (or yellow) fluffy stuff that looks like cotton candy but will itch you into next week if you touch it bare-handed.
Batts: Pre-cut panels – great for even spaces
Loose-fill: Blown-in – better for tight, awkward spots
Good R-value, cost-effective, and doesn’t feed rodents. (But squirrels still try.)
Cellulose Insulation
Made from recycled paper and treated to resist fire, mold, and bugs.
Eco-friendly
Great air sealing when densely packed
Often blown-in to cover the entire attic floor
Bonus: It’s like giving your attic a warm, crunchy granola hug.
Spray Foam Insulation
This is the Cadillac of insulation – fancy, airtight, and excellent at keeping hot air out (and cool air in).
Open-cell: Flexible, air barrier, lower R-value
Closed-cell: Rigid, moisture barrier, high R-value
It costs more but pays for itself over time, especially in tricky attics near McKinney’s luxury neighborhoods like Trinity Falls or Adriatica
Mineral Wool (Rockwool)
Fireproof. Soundproof. Pest-resistant. And heavy-duty.
High R-value
Water repellent
Doesn’t burn until over 2,000°F (so… we’re good)
Radiant Barriers & Reflective Insulation
Best used as a tag-team with other insulation types. Radiant barriers reflect heat; fiberglass/cellulose absorb it. Pair them together, and you’ve got an attic that actually behaves.
