Versatile, Cost-Effective Batt Insulation for Any Project
Batt insulation (also called blanket insulation) is one of the most widely used and versatile insulation options available. Made from fiberglass or mineral wool, batts come in pre-cut panels designed to fit snugly between studs, joists, and rafters—making them ideal for new construction, additions, and renovation projects where wall cavities are accessible.
Whether you're building new, renovating an existing space, or insulating walls and floors, batt insulation provides reliable thermal performance at a competitive price. With options in fiberglass and mineral wool, you can choose the material that best fits your project's needs for fire resistance, soundproofing, and budget.
The Batt Insulation Advantage
Versatile Applications Batt insulation works in walls, floors, ceilings, attics, and more. Its pre-cut sizing makes it adaptable to standard framing in both residential and commercial construction.
Cost-Effective Performance Batt insulation delivers solid thermal performance at a lower cost than spray foam, making it an excellent choice for budget-conscious projects without compromising quality.
Easy Installation in New Construction For new builds and major renovations where wall cavities are open, batts install quickly and efficiently, keeping projects on schedule.
Fire Resistance Options Mineral wool batt insulation offers exceptional fire resistance, making it ideal for fire-rated wall assemblies and areas where fire safety is a priority.
Sound Dampening Both fiberglass and mineral wool batts reduce noise transfer between rooms, creating quieter, more comfortable living and working spaces.
Proven Track Record Batt insulation has been used successfully in millions of homes and buildings for decades, with a long history of reliable performance.
Fiberglass vs. Mineral Wool: Which is Right for You?
Fiberglass Batt Insulation
- R-value: R-3.2 to R-3.8 per inch (depending on density)
- Lightweight and easy to handle
- Most affordable batt insulation option
- Available in various thicknesses and widths
- Fire-resistant when properly installed
- Good sound dampening properties
- Best for: Budget-conscious projects, standard residential applications, most common choice
Mineral Wool Batt Insulation
- R-value: R-3.3 to R-4.2 per inch
- Superior fire resistance (melting point over 2,000°F)
- Excellent sound dampening (better than fiberglass)
- Water-resistant—won’t absorb moisture
- Denser and more rigid than fiberglass
- Made from recycled materials (rock or slag)
- Higher cost than fiberglass
- Best for: Fire-rated assemblies, superior soundproofing, moisture-prone areas, commercial applications

Where We Install Batt Insulation
Interior & Exterior Walls The most common application for batt insulation. Provides thermal protection and reduces sound transfer between rooms or from outside noise.
Floor Systems Insulate floors above unconditioned spaces like crawl spaces, garages, or basements. Improves comfort in rooms above and reduces energy loss.
Cathedral Ceilings Batt insulation fits between rafters in vaulted or cathedral ceilings, providing thermal protection while maintaining the open ceiling design.
Basement Walls Install batts in framed basement walls to improve comfort, reduce condensation, and create finished living spaces.
Garage Spaces Insulate garage walls and ceilings to improve temperature control in attached garages and reduce energy loss to your home.
Band Joists Seal and insulate rim joists (where the foundation meets the floor framing) to prevent air leakage and heat loss.
New Construction & Renovations Batt insulation is perfect for projects where wall cavities are accessible during construction or renovation phases.

Book a Free EvaluationHow much does batt insulation cost?
Batt insulation typically costs $0.50 to $1.50 per square foot installed, depending on the type (fiberglass or mineral wool), R-value, and project complexity. Fiberglass is the most affordable option, while mineral wool costs more but offers superior fire resistance and soundproofing. We provide detailed, transparent estimates during your free evaluation.
What R-value do I need for walls in Georgia?
For Metro Atlanta (Climate Zone 3), the Department of Energy recommends R-13 to R-15 for exterior walls and R-19 to R-21 for floors. We’ll ensure your insulation meets these standards during installation.
Can I install batt insulation myself?
While DIY installation is possible for experienced homeowners, professional installation ensures proper fit, minimal gaps, and maximum performance. Improperly installed batts (compressed, gaps around obstacles, or improper coverage) can significantly reduce effectiveness.
Does batt insulation require a vapor barrier?
In most applications, yes. We install faced batts (with attached vapor barrier) or add a separate vapor barrier as required by building codes for your climate zone and application.
How does batt insulation compare to spray foam?
Batt insulation is more affordable and works well when wall cavities are accessible during construction. Spray foam provides superior air sealing and is better for irregular spaces, crawl spaces, and retrofit applications. We’ll help you choose the best option for each area of your project.
Will batt insulation help with soundproofing?
Yes. Both fiberglass and mineral wool batts reduce sound transfer between rooms. Mineral wool offers superior sound dampening and is often used in media rooms, bedrooms, and commercial spaces where noise control is important.
Can batt insulation get wet?
Fiberglass batts can absorb moisture and should be kept dry. Mineral wool is naturally water-resistant and maintains its R-value even when damp, making it better for potentially moist environments.
How long does batt insulation last?
When properly installed and protected from moisture, batt insulation can last 80-100 years. Unlike blown-in insulation, batts don’t settle over time when correctly installed.
