Why Is Air Sealing Important?
If you want your home to be as energy-efficient as possible, you need to do more than just insulate and ventilate. It would be best to use a sealant to fill those tiny holes that allow air to pass through. If you don’t seal up your home and keep out any unwanted dirt, bugs, and air from the outside, you won’t get the best from your HVAC system or insulation materials, and it’ll cost you more money than it should. You might want to check out our tips for air sealing window sashes for a detailed guide.
That’s because air can leak through tiny holes, heat can escape in the winter, and cool air can escape in the summer, which means that your HVAC has to work even harder to do its job, using more energy to pump up your electric bill.
What Is the Difference Between Sealant and Caulk?
Sealants or caulks are essential because they help ensure that your home is well insulated from the outside environment. It helps keep your home safe from water and air leaks.
Caulk and sealant are typically used to fill spaces between two building materials, and both are designed to be air-tight. The main difference is that caulk is more flexible than sealant and can withstand minor joint movement. Most caulk in the market can contract and expand without cracking in high or low-temperature conditions.
To give you ideas on what caulk is the most effective based on your application, here are five products you can try:
