Home Insulation and Air Sealing – What Are The Differences?

Proper home insulation and air sealing are crucial to making your home safe, comfortable, and energy-efficient. But even if they’re both important, you should know each one’s key differences.

What Does Home Insulation Do?

When you insulate your home, you use high-quality materials to block gaps in your home, including your roof, walls, or floors. This process helps regulate your property’s indoor temperature and soundproof it from any unwanted noise. Some other benefits of insulating your home are:


  • Reducing your energy bills during the winter and summer months
  • Increases your property’s value, especially if energy efficiency is a selling point
  • Reducing your carbon footprint by using less energy to keep your home comfortable
  • Prevents mold and mildew from building up

Before you begin any insulation project, you need to know which type of insulation would be best for your home. For instance, batt insulation is an eco-friendly, cost-effective method that uses fiberglass to protect your home. On the other hand, spray foam insulation uses cellulose to effectively seal any potential gap.

What Is Air Sealing?

Air sealing eliminates any small gaps, cracks, or holes where air may seep in or out of your home. This includes areas such as windows, doors, or places where your home’s foundation meets the framing. Air sealing can also be effective in keeping out insects, complementing your home’s existing insulation, and eliminating any unwanted drafts.

While a few methods are available to air seal your home, caulking and weatherstripping are two of the most common ones used for specific areas around the house. If your property is in the construction phase, house wrapping is generally used around your home as a protective barrier. Additionally, particular types of insulation, like cellulose, are installed using dense packing to reduce airflow through crevices.

Why Both Insulation and Air Sealing Are Important

It’s clear that each method has its clear differences. Insulation creates a barrier against any heat coming in and out, especially during extreme weather. On the other hand, air sealing will block off any small cracks to ensure your living space stays comfortable year-round without overworking your HVAC units.

However, having both is essential to maximizing your home’s energy usage. Air sealing and insulation complement each other, and not having one in your home will still lead to higher energy costs, uneven heating or cooling, or worse. For this reason, investing in high-quality insulation and air sealing will your home’s energy efficiency and get you the most savings possible.
