Sealants are more than a gap fillertheyre a critical component of building envelope resilience In modern construction, especially where thermal cycling, seismic movement, or expansion joints are at play, only sealants with true dynamic joint movement tolerance can keep water, air, and contaminants out over the life of the building.
Procurement leaders, contractors, and envelope designers must carefully evaluate sealants not just by brand, but by movement classification, adhesion performance, and substrate compatibility.
