What is Attic Insulation?
Insulation is measured by its R-value, which indicates its ability to resist heat flow. The higher the R-value, the better the insulation.

• insulation has a thickness of about 10 inches and provides excellent thermal resistance.
• It is one of the most commonly recommended R-values for attics in climates like Los Angeles, where both heat and energy efficiency are major concerns.
• Installing or replacing attic insulation with batts ensures your home or business remains cooler in summer, warmer in winter, and more efficient year-round.

Why Upgrade to Attic Insulation?

1. Energy Efficiency
Heating and cooling account for up to 50% of a property’s energy use. Poor or outdated insulation allows air to escape, forcing HVAC systems to work harder. insulation reduces this energy loss, helping lower utility bills.

2. Comfort Year-Round
batts help maintain consistent indoor temperatures. No more hot spots in summer or cold drafts in winter — your home stays comfortable in every season.

3. Sound Absorption
Fiberglass insulation absorbs sound, reducing noise between rooms and from outside sources. This makes it ideal for urban areas like Los Angeles.

4. Durability
The CertainTeed™ fiberglass batts we use do not rot, deteriorate, or settle over time, ensuring lasting performance.

5. Sustainability

• Made with recycled content that meets EPA standards.
• GREENGUARD Gold Certified for low chemical emissions, promoting healthier indoor air quality.
• Supports reduced energy consumption for the lifetime of your home or building.
