Revamp Your Attic with Lowe’s Blown-In Attic Insulation: Say Goodbye to High Energy Bills!
Introduction
Upgrading your attic’s insulation is one of the smartest investments you can make to cut energy costs and boost home comfort. Blown-in attic insulation from Lowe’s uses finely shredded fiberglass, cellulose, or mineral wool to create a seamless thermal barrier that traps heat in winter and keeps your home cool in summer. Whether you’re tackling an older home with settled insulation or starting fresh in new construction, this versatile solution adapts to irregular spaces, plugs air leaks, and delivers long-lasting performance. In this guide, you’ll learn how blown-in attic insulation works, compare material options, and discover simple steps to install it yourself—so you can revamp your attic and wave goodbye to sky-high energy bills.
Benefits of Blown-In Attic Insulation
• Superior Energy Savings—An under-insulated attic can account for up to 30% of a home’s heat loss. By adding a thick layer of blown-in attic insulation, you create an airtight seal that reduces heat transfer, eases the load on HVAC systems, and typically slashes heating and cooling costs by 10–20%.
• Gap-Filling Power—Loose-fill insulation naturally settles into every nook and cranny, sealing gaps around pipes, wiring, rafters, and uneven framing that batt insulation often misses. The result is a continuous R-value that keeps conditioned air inside where it belongs.
• Sound Reduction—The dense, interlocking fibers of blown-in insulation also dampen airborne noise, making your living spaces quieter and more peaceful—especially welcome if you live near busy streets or noisy neighborhoods.
• Quick, Cost-Effective Installation—Renting a blower machine from Lowe’s makes DIY installation surprisingly fast. In a few hours, you can cover a 1,000-square-foot attic to recommended depths. Professional installation is also available for homeowners who prefer hands-off convenience.
• Long-Term Durability—Unlike batt insulation that can sag or compress over time, blown-in attic insulation resists settling and maintains its R-value for decades. Many products carry limited warranties, giving you peace of mind in the years ahead.
Comparing Types of Blown-In Attic Insulation
Fiberglass
• R-Value: 2.2–2.7 per inch
• Pros: Inexpensive, non-combustible, moisture-resistant, widely available
• Cons: Fibers can irritate skin and lungs; requires protective gear during installation
Cellulose
• R-Value: 3.2–3.8 per inch
• Pros: Made from recycled paper treated with fire retardants, excellent gap-filling, eco-friendly
• Cons: Can settle over time without stabilizer; slightly heavier than fiberglass
Mineral Wool
• R-Value: 3.0–3.3 per inch
• Pros: Naturally fire-resistant, soundproofing, moisture-repellent, no settling
• Cons: Higher cost, may require professional installation
Each material delivers reliable thermal performance, but your choice depends on budget, R-value targets, environmental preferences, and installation comfort. Lowe’s associates can help you calculate the exact material volume based on attic square footage and desired insulation depth.
DIY Guide to Installing Blown-In Attic Insulation from Lowe’s
1. Measure and Plan—Calculate attic square footage and target R-value (R-38 to R-60 for most climates). Use Lowe’s online insulation calculator or in-store chart to determine bags needed.
2. Gather Equipment—Rent a blower machine from Lowe’s rental center. Pick up insulation bags, safety goggles, respirator mask, gloves, long-sleeve clothing, attic light, and a tarp to protect floors.
3. Seal Air Leaks—Before blowing insulation, apply caulk or expanding foam around recessed lights, wiring penetrations, attic hatches, and sill plates to prevent drafts.
4. Load the Blower—Set the machine on a stable surface outside the attic. Insert the hose through the attic access hole and begin feeding insulation per the manufacturer’s instructions.
5. Distribute Evenly—Start at the farthest corner and work back toward the hatch, keeping the hose tip about 4–6 inches above the attic floor. Aim for uniform coverage and use a measuring pole to verify depth.
6. Check Coverage—Once you reach the recommended depth, stop blowing and inspect for thin spots. Touch up by hand or resume blowing in small areas as needed.
7. Clean Up—Disconnect the hose, sweep any stray insulation, roll up the tarp, and return rental equipment. Store leftover bags in a dry location for future touch-ups.
H2: Blown-In Attic Insulation Maintenance Tips
• Annual Inspection—Every fall, check attic insulation depth and look for signs of moisture or pests.
• Top-Up as Needed—If depth falls below the recommended level, add a fresh layer of insulation.
• Ventilation Check—Ensure soffit and ridge vents remain clear to prevent moisture buildup.
