When it comes to improving home comfort and reducing energy bills, few upgrades deliver a better return on investment than air sealing, attic insulation, blown insulation, and fiberglass wall insulation. Whether you’re building a new home or upgrading an older one, combining these insulation strategies helps create a home that’s not just efficient — but also healthier, quieter, and more comfortable all year round.
At Lonestar Air Sealers, we specialize in helping homeowners understand the power of properly installed air sealing and insulation systems. In this post, we’ll break down how air sealing, attic insulation, blown insulation, and fiberglass wall insulation work together to protect your home.
The Importance of Air Sealing
Air sealing is the first and most critical step in creating an energy-efficient building envelope. Without air sealing, even the best attic insulation and fiberglass wall insulation won’t perform at full capacity.
Tiny gaps and cracks around windows, doors, light fixtures, attic hatches, plumbing penetrations, and electrical outlets allow conditioned air to escape and outside air to enter. This leakage leads to drafts, uneven temperatures, moisture issues, and high utility bills.
By professionally air sealing your home, especially in the attic, walls, and crawl spaces, you can:
-
Prevent energy loss
-
Improve indoor air quality
-
Block dust, allergens, and moisture
-
Maximize the performance of attic insulation, blown insulation, and fiberglass wall insulation
At Lonestar Air Sealers, our air sealing experts identify hidden leaks and seal them using durable materials for long-lasting efficiency.
Attic Insulation: Your First Line of Defense
Once your attic is properly air sealed, the next essential upgrade is attic insulation. Without enough attic insulation, your HVAC system has to work overtime to keep up with outside temperatures.
Properly installed attic insulation helps:
-
Maintain consistent indoor temperatures
-
Reduce heating and cooling costs
-
Prevent ice dams and moisture buildup
-
Increase overall home comfort
We recommend pairing attic insulation with air sealing for best results. At Lonestar Air Sealers, we often use blown insulation in attics to achieve thorough coverage, especially in hard-to-reach corners and around joists.
Why Blown Insulation Is Ideal for Attics
Blown insulation — also known as loose-fill insulation — is one of the most efficient and cost-effective ways to insulate an attic. Made from cellulose or fiberglass, blown insulation can fill irregular spaces more effectively than traditional batt insulation.
Benefits of blown insulation include:
-
Fast and efficient installation
-
Superior coverage and reduced gaps
-
Excellent soundproofing and thermal performance
-
Compatibility with air sealing for maximum effectiveness
At Lonestar Air Sealers, we specialize in combining air sealing with blown insulation to ensure your attic performs like a thermal barrier. When used together, air sealing and blown insulation can significantly improve your home’s energy performance.
Don’t Forget About Fiberglass Wall Insulation
While the attic is a top priority, fiberglass wall insulation is just as important when it comes to whole-home energy savings. Walls make up a large surface area of your building envelope — if they’re not properly insulated, you’re losing conditioned air and comfort.
Fiberglass wall insulation offers:
-
Excellent thermal resistance (R-value)
-
Fire and moisture resistance
-
Long-term durability
-
A cost-effective solution for retrofits or new builds
Installing fiberglass wall insulation in conjunction with air sealing and attic insulation helps create a complete thermal envelope. At Lonestar Air Sealers, we install high-quality fiberglass wall insulation in exterior walls, garage walls, bonus rooms, and more.
Combining All Four: The Gold Standard of Home Efficiency
The most efficient homes rely on a layered approach:
-
Air sealing to stop leaks
-
Attic insulation to control temperature
-
Blown insulation to cover irregular attic spaces
-
Fiberglass wall insulation to insulate wall cavities
Together, these four elements form a comprehensive strategy that maximizes comfort, minimizes energy waste, and protects your home from outside elements. Whether you’re retrofitting an older home or improving new construction, Lonestar Air Sealers can help you design a custom plan using air sealing, attic insulation, blown insulation, and fiberglass wall insulation.
