Insulation plays a critical role in making homes comfortable, energy-efficient, and peaceful. Without enough insulation, rooms may feel unevenly heated or cooled, energy bills can rise unnecessarily, and outside noises become harder to ignore. Attics, in particular, are one of the simplest areas to upgrade, providing homeowners in San Fernando Valley an excellent opportunity to improve their home’s performance. The question is: which type of insulation is best for this space?

Advantages of Blown-In Fiberglass

Fiberglass insulation comes in a range of sizes and thicknesses, making it versatile enough to be used in attics, walls, garages, and crawl spaces. Blown-in fiberglass is especially efficient at filling tricky spots—corners, tight edges, and around framing—that other insulation types might miss.

Several benefits stand out when considering blown-in fiberglass:

• Improved energy efficiency
• Cost-effective solution
• Natural fire resistance
• Simple installation process
• Sound-dampening properties
• Environmentally friendly choice

Comparing Blown-In Fiberglass to Other Options

For most homes across Southern California, blown-in insulation (or loose-fill) tends to be the optimal choice. A specialized machine blows small bits of fiberglass into place, covering every gap and the attic’s floor joists. This method ensures that heat doesn’t escape through the wood, helping homeowners save on energy costs.

Spray Foam: Is It Worth the Price?

Spray foam insulation creates a barrier against heat, air, and moisture. It adheres directly to surfaces and solidifies into a long-lasting layer. This insulation option works well in spaces where the attic is used for living or storage, or if the home’s ductwork runs through the attic. However, spray foam’s significant price tag—three to four times higher than fiberglass—makes it a less attractive choice unless its specialized benefits are truly needed.

Considering Fiberglass Batt Insulation

Another common form of insulation, fiberglass batts, consists of pre-cut sections of fiberglass designed for easy placement. Though this type is frequently found in attics, it often proves less efficient. Fiberglass batts fit snugly only in areas where rectangular spaces of a standard size exist. When cavities aren’t completely filled, the insulation doesn’t perform at its full potential, leading to wasted energy and higher utility costs.

How Much Insulation Should Your Attic Have?

Even a small amount of insulation is better than none, but many homes across Los Angeles County don’t have enough to achieve peak performance. Take a quick look at your attic. If the insulation measures just 3 or 4 inches in height or if floor joists are visible, it’s a sign that you could benefit greatly by adding more.
