Air Sealing

Yes, caulking and silicone are commonly used for air sealing purposes.

Caulking:

Caulk is an effective material for sealing gaps, cracks, and joints in various surfaces. It can be used to fill small to medium-sized gaps around windows, doors, baseboards, and other areas where air leakage can occur. Caulk creates an airtight seal, preventing the exchange of air between the inside and outside of a building. By sealing these gaps, caulking helps to reduce drafts, prevent energy loss, and improve the overall comfort and energy efficiency of a space.

Silicone:

Silicone sealants, like caulking, are also suitable for air sealing. They are particularly useful in areas exposed to moisture, such as bathrooms and kitchens. Silicone sealants can effectively seal gaps and joints around fixtures, countertops, and plumbing penetrations, preventing air leakage and minimizing the entry of unwanted drafts, odors, and moisture. Additionally, silicone's flexibility allows it to withstand movement and expansion, ensuring a durable and long-lasting air seal.

When considering air sealing, it's important to take a comprehensive approach, addressing all potential areas of air leakage, including windows, doors, electrical outlets, and other points of penetration. Combining caulking or silicone sealants with other air sealing measures, such as weatherstripping and insulation, can further enhance the overall effectiveness of air sealing efforts.
