Attic Insulation Upgrade Plan
A well-insulated blown-in insulation creates a thermal barrier that prevents warm air from seeping into living areas in the winter and scorching hot outdoor air from entering homes in the summer. This minimizes energy waste, helping your HVAC system run more efficiently and reducing utility bills.
An attic insulation upgrade is one of the most cost-effective home improvement projects you can undertake, delivering big savings over time. And, in California, you can often qualify for rebates from local utilities like SDG&E and PG&E for energy-efficient upgrades that meet the state’s Title 24 standards.
In this article, FHB contributing editor Mike Guertin walks you through some relatively inexpensive techniques for tuning up your attic’s insulation and minimizing air leaks to make your home more energy-efficient. He starts by pointing out common sources of air leaks in attics, including gaps around recessed lights and electrical boxes, plumbing or electrical chases, framing, chimneys and other penetrations, then provides tips for sealing them with caulk and spray foam.
Next, he recommends checking your existing fiberglass batt insulation to ensure it has a minimum R-value of about 30. And he suggests adding more insulation, such as blown-in cellulose, which has a higher R-value and is effective in hard-to-reach spaces. This environmentally friendly insulation is made from recycled paper that has been treated for fire and pest resistance.
In many cases, homeowners can make these attic insulation upgrades themselves with a little DIY help. However, proper installation is essential to maximize energy efficiency and avoid costly mistakes. Working with a professional contractor to complete an attic insulation upgrade can also help ensure your project meets Title 24 standards and is compatible with your roof and solar systems.
