Window sealants are crucial for maintaining windows and improving your HVAC system’s energy efficiency. They protect your house from drafts, heat leakage, and moisture intrusion that can force your HVAC system to work harder to keep your home comfortable. The best sealants can provide quality protection for years. Listed below are the best types of window sealants available.
Silicone Caulk
Silicone caulk is one of the best window sealants. The seal it provides can last for more than 20 years against both exterior and interior windows. Silicone caulk is fully waterproof, it typically dries fast, it starts working within minutes of application, and it doesn’t crumble in cold or hot temperatures. These qualities make it a great option for sealing exterior windows.
Silicone can emit a strong odor as it dries. You can’t paint over most silicone caulks. However, you can get tinted gray, white, or black silicone caulks to complement various window finishes.
Polyurethane Sealant
Polyurethane is a popular sealing material. It’s weatherproof, so you can use it as an exterior caulk. You can easily apply polyurethane caulk with a caulk gun and trim it easily. You can paint over polyurethane caulk. Polyurethane foam, a different kind of polyurethane sealant, is mainly used for door and window installations. It fills rough openings and seals large gaps without bending the frames.
Polyurethane sealants can be health hazards. Therefore, wearing gloves and a respirator when applying them is important.
Acrylic Latex
Acrylic latex caulk is thin and smooth, so you can easily apply it. It’s nontoxic and doesn’t give off a harsh odor, making it an excellent choice for sealing interior windows. You can paint it to match your window finish, and you can clean up excess caulking easily with water. However, if you’re looking for a sealant for exterior applications, acrylic latex caulks won’t cut it.
Curing times and handling vary among the different window sealants, so be sure to follow the product instructions. If you need HVAC products or services in the Lorain area, contact us at Energy 1 Heating & Air Conditioning. We have more than 50 combined years of HVAC experience.
