![]() We take time to precisely analyze how the parts work with the whole. The advantage of doing this is simple: we observe potential problems firsthand, and engineer solutions as a team. Testing is performed first by our own team of engineers. Here, we subject our prototypes to severe simulated weather and atmospheric events to examine performance and suitability. The wall's unique wall-and-control panel design is the industry s Gold Standard for accuracy in testing. Viwinco Windows 6ġ2 The Gold Standard Our 30,000-square-foot, on-site state-of-the-art Research and Development Center is home to our own certified test wall. A Combination of Checks: Tempered glass is both visually inspected and measured with a series of gauges to ensure it meets industry standards for optical clarity. After the glass is cooled, it is placed on a cart and sent to the insulated glass department. The length of time the glass is heated depends on its thickness. Once it is washed, the glass is sent through to the tempering oven. Next, the glass proceeds through our seaming line, where the edges are polished. First, we laser-etch the Viwinco certification logo onto each piece of glass. A surface compression of 10,000 psi or more and an edge compression of 9,700 psi or more ensures that, if the glass does break, it will fracture into tiny cubes referred to as "dice." 1. From the compression comes strength: tempered glass is four or five times as strong as regular annealed glass. The process requires glass to be heated to approximately 1200 F and then immediately force-cooled with air nozzles to create surface and edge compression. Tempered glass is the other essential in laminated glass units. Also referred to as safety glass, it shatters into small cubes when broken, as opposed to jagged shards. Viwinco Windows 4ġ1 Glass Tempering Rollers feed the glass into the tempering oven. Above: The two layers of glass, with PVB laminate sandwiched in between, adhere to each other after having been heated in an infrared oven. This protects the glass from impurities, helping to ensure that nothing interferes with the lamination process. Left: Assembling laminated glass in a clean room, which is dust-free and controlled for temperature and humidity. Laminated glass consists of a piece of.090 polyvinyl butyral (PVB) a resilient, flexible interlayer pressed between a double-pane of clear glass and a pane of tempered Solarban 60 low-e glass. Viwinco operates dedicated tempering and laminating departments, both of which utilize the most technologically advanced equipment and function under the leadership of an expert staff. Since we control the source, we also control the quality of every single window that leaves our 140,000-square-foot manufacturing facility. Viwinco s production methods make us one of the most trusted and reliable manufacturers of impact products in the country. ![]() 1 OceanViewĩ Conceived of, Designed, Manufactured and Tested In House. OceanView windows are certified impact-resistant preventing wind and debris from entering the house, lifting up the roof and pushing the walls outward. With all this knowledge, we designed and introduced the next generation of windows: our certified impact-resistant OceanView line. We added in-house laminating and tempered glass lines to our manufacturing facility, obtained our own specialized air canon, and within our test facility fired projectiles at windows until we learned exactly how not to penetrate the glass. Products that would stand up to brutal weather conditions and prevent the destruction caused to homes along the coast by gusting, turbulent winds and wind-borne debris. We had our eyes on a goal: to create products of the future. Over twenty years ago, during a decade of extreme weather conditions such as Hurricane Andrew and other natural disasters, Viwinco invested significant time and resources in expanding our study of the science of windows.
