Which materials are recommended for sealing in construction?

The selection of recommended materials for sealing in construction is primarily guided by their performance characteristics and suitability for various applications. Chloroprene or polyurethane is particularly valued for its strong adhesive properties, flexibility, and durability, making it ideal for use in environments that may experience temperature variations and which require a long-lasting seal. These materials can effectively resist moisture, UV exposure, and a range of chemicals, making them suitable for both interior and exterior applications.

In contrast, while butyl sealants and silicone sealants also serve as effective sealing options in certain contexts, they tend to have limitations when it comes to specific applications or conditions. For example, butyl sealants may not perform as well under UV exposure compared to chloroprene or polyurethane. Silicone sealants, while excellent for flexibility and water resistance, might not adhere well to all surfaces, particularly if the surfaces are dirty or wet.

Polyester, mentioned as an option, is generally not recognized as one of the primary sealing materials in construction. While it has its uses in certain applications, it does not offer the same level of performance and versatility as chloroprene or polyurethane sealants.

Overall, the recommendation of chloroprene or polyurethane reflects an understanding of the need for a strong, adaptable sealant that
