In just about every climate in which we live and build, the number one job of any building envelope is to keep the outside environment out. Many building products offer help, but without detailed attention to the joints, many systems fail. Weather-Bloc believes that using advanced sealing and gaskets products at these joints is critical for successful long-term building continuance.

Our gaskets are designed to work where the two surface meet but are in constant movement. This movement is caused by concrete and wood expanding and contracting but our Advanced Closed Cell Foam gasket with Micro-Grab™ Adhesive Technology has the ability to move and rebound and accommodate this movement and seal those joints.

Many contractors put a lot of faith in caulks and wet-applied sealants but Weather-Bloc’s gasket sealing systems sustain their performance over time in lab testing and field results. Our building sill sealers and gaskets protect the structural framing from moisture damage, help prevent bug and rodent intrusion and stops drafts maximizing energy efficiency.
