Everyday contractors fill in holes in our walls and roofs by installing windows, doors and skylights to seal up these opening. Complicating this matter even more, we expect our windows, doors and sometimes skylight to be able to open and close and yet keep air and moisture out. One hundred percent sealing of these opening under wind and moisture pressure of 100 mph for the next 20 years is next to impossible. We need to accept that these opening will at sometime leak. Weather-Bloc understands this phenomena and has designed numerous products to control this dilemma - we call it Weather-Bloc Moisture Management.

Weather-Bloc manufacture two types of window and door products:
1) products that are air and moisture barriers.
2) products that manage the moisture and move it out of the structure.

Due to Our Micro-Grab™ Adhesive Technology, our Advanced Closed Cell Foam Gaskets and our cutting-edge Pan Systems, Weather-Bloc Systems is the premier manufacturer in sealing, energy saving and moisture management systems of windows and doors in all of North America.
