In what scenarios are elastomeric sealants especially beneficial?

Elastomeric sealants are particularly beneficial in scenarios where there is a risk of joint movement. This is primarily due to their flexibility and ability to accommodate changes in shape and volume that occur as a result of thermal expansion, contraction, or even seismic activity. Their elastic properties allow them to maintain a seal even when the substrates to which they are applied undergo movement. This is crucial in preventing the penetration of fire, smoke, or water, thereby preserving the integrity of the firestop system.

In environments subject to significant temperature fluctuations, vibrations, or structural shifts, elastomeric sealants provide a reliable solution that can adapt to these changes without losing their effectiveness. This adaptability is essential in ensuring long-term performance and safety in firestop applications, making them a preferred choice for joints and gaps that are likely to experience movement over time.
