Choosing new windows that will last season after season, regardless of what Mother Nature throws at them, is something that no homeowner should ever have to compromise on. In doing so, it’s important to pay close attention to your windows’ Design Pressure rating. DP index is a carefully-structured set of guidelines that have been defined by AAMA, WDMA and NFRC, to accurately measure how much pressure a window can realistically sustain before suffering permanent damage from wind, rain, snow and other elements.
If superior protection and long-lasting window reliability rank high on your list of concerns, the professionals at Wonder Windows are here to help you find windows with the highest design pressure rating. Call our Rochester or Buffalo locations to learn more or get started.
