Applying sealant to exterior gaps and cracks during colder temperatures presents unique challenges and requires specific considerations. For instance, certain sealant formulations may become too viscous for proper application below a specific temperature threshold, potentially leading to an inadequate seal. Conversely, some sealants designed for low-temperature application offer flexibility and adhesion in freezing conditions.
Maintaining a weathertight building envelope is crucial year-round for energy efficiency and preventing moisture damage. Historically, various materials have been employed for sealing, from rudimentary mixtures of natural ingredients to the sophisticated polymer-based sealants available today. Effective sealing in cold weather significantly reduces drafts, minimizing heat loss and lowering energy costs. It also safeguards against water intrusion, which can freeze and expand, causing structural damage and promoting mold growth.
