Insulation 101: Airsealing

May 24, 2022

Heating and cooling make up the most energy usage in a residential home, so it's important to retain that good air inside the home while keeping outside air out. Enter AIRSEALING!

What is Airsealing?

Airsealing is the process of stopping the passage of air or vapor with material. In other words, keeping inside air inside and outside air outside.  

How does airsealing work?

Airsealing is achieved by applying caulk or weather stripping to areas that have air leaks in order to fill cracks, holes, and other openings in your building envelope. 

What are the benefits of airsealing?

For starters, by keeping outdoor air outside, your indoor air quality will drastically improve after air sealing. Airsealing reduces bacteria, allergens, and other outdoor pollutants inside. 

Additionally, airsealing will improve the quality of your home in several ways: less moisture, less pests, less hvac loss, and lowered energy costs. 

Does a home need to breathe? 

It does not need to breathe, but it does need to ventilate in a controlled manner. Airsealing your home will stop unwanted "breathing" and your home will continue to have proper ventilation through controlled airflow such as your HVAC system, air quality devices, and attic or crawl space vents. 

How do I airseal?

Most basic air sealing can be done by anyone. If you have a drafty window or door, sealant products and door sweeps are available in hardware stores and can be applied in minutes.

However, some air leaks may be harder to spot and resolve. Many leaks occurring in a home are around the foundation or basement as well as in the attic. Hiring a qualified expert like Koala Insulation will ensure your large air leaks in these areas are resolved to seal up your home's building envelope so you can enjoy less moisture, less pests, cleaner air, lower energy costs, and a more comfortable indoor climate.
