The process of creating an airtight barrier around window frames, preventing air and water infiltration, is a crucial aspect of home maintenance. Effectively addressing gaps or deteriorated sealant minimizes energy loss and potential structural damage. An example includes applying caulk to the perimeter of a window where it meets the siding or interior wall to block drafts.
Maintaining the integrity of window seals offers significant advantages. Reduced energy bills stem from minimizing heat transfer, while preventing water intrusion mitigates the risk of mold growth and wood rot, preserving the building’s structural soundness and indoor air quality. Historically, various materials, from tar to modern polymers, have been employed to achieve this critical barrier, reflecting advancements in building science and material technology.
