Attic Insulation: The Key to a More Comfortable and Energy-Efficient Home

When it comes to creating a comfortable home and lowering monthly energy bills, attic insulation often takes center stage—and for good reason. Your attic plays a major role in regulating indoor temperatures, especially during Washington’s chilly winters and warm summers. At Kent Spray Foam Insulation, we specialize in helping homeowners maximize energy efficiency, improve indoor comfort, and protect their homes year-round with high-quality attic insulation services.

In this guide, we’ll break down why attic insulation matters, the different types available, and how upgrading your attic can transform your home’s comfort and performance.

Why Attic Insulation Matters

Many homeowners don’t realize how much heating and cooling loss happens through the attic. In fact, the U.S. Department of Energy estimates that up to 25% of a home’s heat loss occurs through an under-insulated attic. When this happens, your HVAC system must work harder, resulting in higher utility bills and uneven temperatures throughout the home.

Some of the biggest benefits of proper attic insulation include:

✔ Lower Energy Bills

By preventing heat from escaping in winter and entering in summer, insulation allows your HVAC system to operate efficiently. Many homeowners see a 20–40% reduction in energy costs after upgrading attic insulation.

✔ Consistent Indoor Comfort

No more cold bedrooms, drafty hallways, or hot upstairs rooms. Insulation helps keep temperatures stable throughout the home.

✔ Improved Indoor Air Quality

Insulation blocks dust, pollutants, and outdoor allergens from entering your living space.

✔ Moisture & Mold Prevention

A well-insulated attic helps control humidity and prevents condensation—two major contributors to mold growth.

✔ Increased Home Value

Energy efficiency upgrades like attic insulation are highly attractive to buyers and offer a great return on investment.

Types of Attic Insulation

At Kent Spray Foam Insulation, we offer a range of insulation solutions to meet different home needs and budgets. Here’s a closer look at the most popular types:

1. Spray Foam Insulation (Most Recommended)

Spray foam is a top choice for attic insulation because it provides the highest R-value per inch, superior air sealing, and long-term durability.

Benefits of Spray Foam:

• Excellent air barrier

• Mold and moisture resistant

• Reduces noise

• Expands to fill cracks and gaps

• Lasts 20–30+ years without losing effectiveness

If energy savings and comfort are your top priorities, spray foam insulation is the best option.

2. Fiberglass Insulation

Fiberglass insulation is a cost-effective and commonly used option. It comes in batts or loose-fill form and provides good thermal protection.

Benefits of Fiberglass:

• Budget-friendly

• Non-flammable

• Efficient for large open attic areas

While it doesn’t offer an airtight seal like spray foam, it still provides reliable performance when installed correctly.

3. Cellulose Insulation

Made from recycled materials, cellulose is an eco-friendly option that delivers excellent coverage and reduces heat transfer effectively.

Benefits of Cellulose:

• Environmentally friendly

• Great for insulating around pipes and wiring

• Reduces noise

It’s often blown into attic spaces for seamless, uniform insulation.

Signs Your Attic Needs New Insulation

If you're unsure whether your attic needs an upgrade, watch for these common signs:

• High heating or cooling bills

• Uneven temperatures in different rooms

• Cold drafts

• Hot upstairs rooms

• Moisture or mold in the attic

• Old or deteriorating insulation

• Icicles or ice dams forming on the roof in winter

If any of these sound familiar, it may be time to schedule an inspection with our team.
