What material is often used to seal gaps and joints in construction?

Silicone caulk is a highly versatile sealing material commonly used in construction to fill gaps and joints. It is known for its flexibility and water-resistant properties, which make it ideal for applications such as sealing windows, doors, and other areas where moisture protection is crucial.

Silicone caulk adheres well to various surfaces, including glass, metal, and plastic, ensuring a tight seal that helps prevent air and water infiltration, which could otherwise lead to energy loss and potential damage from moisture. Its ability to withstand temperature fluctuations and remain pliable over time adds to its effectiveness in maintaining a seal, making it a dependable choice for contractors.

In contrast, wood glue is primarily used to bond wooden surfaces together rather than sealing gaps. Nails are fasteners used in construction to hold materials in place rather than serve a sealing function. Drywall joint compound is intended for smoothing out seams between drywall panels but does not perform as a sealant for exterior applications like silicone caulk does.
