Builder and contractor shows are fun and JLC is no exception. Where else does someone put vinyl and then fiberglass on dry ice and drop hammers on them, or hit them? IN this video, Matt Risinger, master builder, is doing an extreme demo. When the vinyl is impacted, parts go flying. Check the video out to see how much fun they have. When it's the fiberglass rod's turn, however, it's remarkably stable. The fiberglass represents the Integrity Window by Marvin. If it's going to be on your house for decades, it's the kind of frame you want. Another product, PolyWall, fluid apply, weather resistant barriers. Check out the video and see both products!
