Based in Holland, Ohio, we saw an opportunity to make a significantly better, stronger, longer lasting product. How did we do it? We listened. From the beginning, we paid attention to what our dealers and homeowners wanted. We began producing vinyl replacement windows and doors in 1988. By the mid-1990s, we were creating vinyl patio sunrooms. Today, we are focused on creating an efficient, technologically-advanced operation, with a product that still responds to the needs and desires of our customers
