For coastal or inland projects specifying DP-50 requirements, consider Quaker’s Crusader Series vinyl windows, a heavy-duty DP-50 alternative to a standard vinyl windows. Our Crusader DP-50 product was developed because high winds aren’t just limited to the Gulf Coast, Pacific Rim or Atlantic Seaboard. The Upper Midwest, Plains States, Great Lakes Region and inland areas off the coasts all get their fair share of extreme, gusty weather.
It should be noted that several models from our Brighton Series wood clad window line have design pressure ratings of 50 or higher right out of the box. No upgrades necessary for DP-50 building codes.
