Expert Spray Foam Insulation Services in Plano, TX
Batt insulation — pre-cut fiberglass or mineral wool panels — is one of the most widely used insulation methods in residential construction, and one of the most misinstalled. Compressed batts, gaps around wiring, and misfit cuts around framing can reduce effective R-value by 20% or more. CoreLine technicians install batt insulation the right way: precision-cut, friction-fit, and properly faced.
We install both fiberglass and mineral wool batts depending on the application. Fiberglass batts are the cost-effective standard for most wall cavities, floors, and attic knee walls. Mineral wool batts offer superior fire resistance and soundproofing — often the right choice for party walls, attached garages, and mechanical room walls. We’ll recommend the right product for your specific project.
Batt insulation is most cost-effective when walls or floors are already open — during renovation, new construction, or after water damage. If your walls are finished, blown-in insulation is usually a better fit. CoreLine will evaluate your home and recommend the approach that delivers the best performance for the cost.

Can’t say enough about the fabulous job that core line did on my attic insulation. Guys came on time and immediately started working. Removed all of my old insulation, sanitized the attic and then replaced everything. Spent time cleaning up every area inside and outside my home. Highly recommend core line.

Professional, Efficient, and a Massive Difference in Home Comfort!
I recently hired CORELINE INSULATION to upgrade the energy efficiency of my home here in the DFW area, and I couldn't be more impressed.
From the initial consultation to the final cleanup, the entire process was seamless.
The team was incredibly knowledgeable and took the time to explain exactly where my home was losing energy.
They didn't just try to sell me a service; they provided a clear plan to help lower my electricity bills and make our rooms feel more consistent in temperature.
A few things that stood out: Professionalism: They arrived right on time and were very respectful of my home, using drop cloths and ensuring everything was spotless before they left.
Expertise: You can tell they know the Texas climate.
They recommended the perfect solution for our specific attic layout. Immediate Results: I noticed a difference in how little my A/C cycled on within 24 hours of the job being finished. If you’re looking for a reliable, local company that actually delivers on its promises of energy efficiency, I highly recommend CORELINE INSULATION.
It truly is an investment that pays for itself in comfort and savings!
Thanks again to CORELINE INSULATION FOR AN EXCELLENT JOB WELL DONE!

FAQ
Frequently Asked Questions About Batt Insulation in Plano
How much does batt insulation cost in Plano, TX? +
Every batt insulation project is different — cost depends on square footage, material (fiberglass vs. mineral wool), and whether old insulation needs to be removed first, which adds to project cost on retrofit jobs. Give us a call and we’ll come out to provide a tailored, no-obligation estimate. Our minimum project cost is $1,500.
What’s the difference between fiberglass and mineral wool batts? +
Fiberglass batts are lighter, widely available, and cost-effective — ideal for most residential applications. Mineral wool (Rockwool) batts offer better fire resistance (melts at 2,150°F vs. 1,100°F for fiberglass), superior soundproofing, and are naturally hydrophobic. We stock both and recommend based on your specific application.
Where does batt insulation work best in a Plano home? +
Batt insulation excels in open-stud walls during renovation, attic knee walls, floors over unconditioned spaces, and between floor joists. It’s also commonly used in new construction where framing is fully accessible. For finished walls or tight attic cavities, blown-in or spray foam is usually a better fit.
Can I install batt insulation over existing insulation? +
In some attic applications, yes — unfaced batts can be installed perpendicular to existing batts for additional R-value. However, we assess the existing insulation for moisture, pest damage, and settling before recommending an overlay. In some cases, removal and replacement is the better investment.
Is CoreLine licensed and insured in Texas? +
Yes. CoreLine Insulation is fully licensed and insured in Texas, BBB accredited, and Greenguard Gold certified. All installations carry our workmanship warranty.
