Fiberglass Door Pre-hung Rough Openings & Design Pressure Unit Information
The chart below lists rough opening dimensions, unit sizes, and “DP” Design Pressure ratings and Impact Approvals for all of our standard “inswing” entryway configurations for our Premium Fiberglass Doors. Most of these entryway configurations have been approved by state regulatory entities for use in windstorm areas. Note that the “rough opening size” listed below is a “tight” size, and is for reference only. Your installer may wish to add to these rough opening sizes. It is important to measure your pre-hung entryway unit upon arrival at the job site, and to construct the opening to fit the individual entryway unit. “Inswing” and “outswing” units are 7/8" undersized. In the chart below, “N/A” means that the product is not available OR the product configuration has not been tested for a DP Rating. For the most up-to-date information and test results for “outswing” entryways, please check your state regulatory website and/or our GlassCraft company website at www.glasscraft.com .
