Which factor should be considered when selecting elastomeric materials for joints in construction?

When selecting elastomeric materials for joints in construction, considering temperature ranges and flexibility is crucial because these factors directly impact the performance and longevity of the materials in various environmental conditions. Elastomeric materials are designed to accommodate movement and thermal expansion or contraction in structures, which can occur due to temperature fluctuations.

Understanding the specific temperature ranges in which the materials will operate ensures that the elastomers will maintain their flexibility without becoming brittle or losing integrity. Furthermore, the ability of the material to flex without compromising its sealing ability is essential in preventing water and air infiltration, which can lead to damage and inefficiency in the building envelope. Thus, focusing on temperature ranges and flexibility ensures that the selected material will perform reliably throughout its intended lifespan, contributing effectively to the structural integrity and safety of the building.
