Attic Insulation

When people think of making their homes more energy-efficient, they often imagine solar panels or energy-saving appliances. But there's a simpler, more cost-effective solution sitting right above your head: attic insulation. At Kent Insulation, we know just how important this unsung hero is to your comfort, energy bills, and even your health.

In this post, we’ll walk you through everything you need to know about attic insulation—what it is, why it matters, the types available, and how to make the best choice for your home.

Why Attic Insulation Is So Important

Let’s start with the basics. Heat rises, which means in winter, warm air naturally heads up toward your ceiling—and eventually, into your attic if it’s not properly insulated. In the summer, a poorly insulated attic can become a giant oven, making it harder to keep your living space cool. The result? Your HVAC system works overtime, and you pay the price with higher energy bills.

Here are some key benefits of attic insulation:

• Energy Efficiency: Proper attic insulation can reduce your heating and cooling costs by up to 30%.

• Home Comfort: Say goodbye to drafty winters and stifling summers. Insulation helps regulate indoor temperatures year-round.

• Environmental Impact: Using less energy means a smaller carbon footprint. It’s a win for you and the planet.

• Increased Home Value: Buyers love energy-efficient homes, making insulation a smart investment.

• Moisture Control: Insulation can help prevent condensation and the mold or mildew that comes with it.

Signs You Need New or Better Insulation

If you're wondering whether your attic insulation is doing its job, here are some signs to look out for:

• Uneven temperatures in different rooms

• Higher-than-usual energy bills

• Ice dams on the roof in winter

• Drafts, especially upstairs

• Old insulation (over 15–20 years) or visibly compressed, damp, or moldy material

Not sure what’s up there? No problem. A professional assessment from a trusted company like Kent Insulation can tell you everything you need to know.

Types of Attic Insulation

There’s no one-size-fits-all approach to attic insulation. Your best option depends on your climate, home size, and existing insulation. Here’s a breakdown of the most common types:

1. Batt (Blanket) Insulation

Made from fiberglass or mineral wool, this type comes in rolls and is laid between attic joists. It’s affordable, easy to install, and a popular DIY choice.

Pros: Inexpensive, readily available
Cons: Less effective if joists are irregularly spaced or there are obstructions

2. Blown-In (Loose Fill) Insulation

This method uses a blower to fill the attic with loose fiberglass or cellulose. It’s perfect for attics with lots of nooks, crannies, and obstructions.

Pros: Excellent coverage and efficiency
Cons: Requires special equipment and professional installation

3. Spray Foam Insulation

Spray foam expands to fill cracks and gaps, offering both insulation and air sealing. It’s ideal for complex or oddly-shaped attic spaces.

Pros: High R-value, great air sealing
Cons: More expensive and requires professional application

Understanding R-Value

R-value is a measure of thermal resistance—the higher the R-value, the better the insulation. The recommended R-value for attics in most parts of Canada and northern U.S. is R-49 to R-60. If your home doesn’t meet this standard, you're likely losing energy and money.

DIY or Professional Installation?

While some insulation jobs can be DIY-friendly, attic insulation is often best left to professionals. A qualified team like ours at Kent Insulation ensures:

• Proper material selection

• Correct and even installation

• Safe handling of materials (especially with older homes that may contain asbestos)

• Identification of ventilation or moisture issues

A botched job can do more harm than good—think trapped moisture, mold, or poor airflow. With professionals, you get peace of mind and long-term savings.

Don’t Forget Ventilation

Insulation and ventilation go hand in hand. Without proper attic ventilation, trapped heat and moisture can lead to mold, rot, or even roof damage. A well-insulated attic should still be able to “breathe.” At Kent Insulation, we always assess ventilation as part of our insulation services.

Final Thoughts

Attic insulation might not be glamorous, but it’s one of the smartest ways to boost your home’s comfort, efficiency, and value. Whether you’re dealing with hot upstairs rooms, cold winter drafts, or rising energy bills, it might be time to look up—literally.
