Blown-in fiberglass insulation is one of the most cost-effective ways to upgrade an attic in the Dallas–Fort Worth area. Loose-fill fiberglass is blown in to a precise depth, flowing around joists, wiring, and obstructions to create a seamless thermal blanket that traditional batts can't match.
If your North Texas home has hot upstairs bedrooms, an HVAC system that never seems to keep up, or insulation that has settled and thinned over the years, adding blown-in fiberglass is often the highest-impact, lowest-cost improvement you can make.
How Blown-In Fiberglass Improves Comfort & Efficiency
Most attics lose efficiency because insulation is uneven, compressed, or simply too shallow for the Texas climate. Blown-in fiberglass solves that by delivering uniform coverage at the R-value your home actually needs, reducing heat transfer through the ceiling, easing the load on your air conditioner, and keeping rooms more consistent floor to floor.
Topping Off Existing Insulation
You don't always need to start from scratch. In many DFW homes we can blow new fiberglass directly over existing insulation to bring the attic up to a modern R-value. If the existing material is contaminated or damaged, we'll recommend removal and sanitation first for the best long-term result.
Benefits of Blown-In Fiberglass Insulation
- Even, gap-free coverage around joists and obstructions
- Excellent cost-to-performance value for attics
- Quickly raises R-value to meet today's energy standards
- Helps eliminate hot and cold spots between rooms
- Non-combustible and resistant to moisture damage
- Can be added on top of existing attic insulation
Frequently Asked Questions
What R-value do I need for an attic in North Texas?
The U.S. Department of Energy recommends roughly R-30 to R-60 for attics in our climate zone. We measure your current insulation depth and top it off to the right R-value for maximum comfort and savings.
Can you add blown-in insulation over my old insulation?
In most cases, yes. If your existing insulation is clean and dry, we can blow new fiberglass on top to reach a higher R-value. If it's contaminated or water-damaged, we'll remove and sanitize first.
Is blown-in fiberglass better than spray foam?
They solve different problems. Blown-in fiberglass is the most affordable way to raise attic R-value, while spray foam also air-seals the envelope. Many homeowners combine air sealing with blown-in insulation for the best value.
