Design Pressure (DP) testing measures the performance of fenestration products to withstand positive and negative pressures. To provide design pressure performance specifically attributed to doorglass, Western Reflections doorglass frame and IG combinations were tested in fixed door slabs to isolate and focus all design pressure against the doorglass assembly. Doorglass design pressure performance is superior to door system design pressure performance.
The 2010 Florida Building Code (FBC) has wind zone specific performance requirements. A design pressure standard is defined for all projects located in the state. Other states continue to adopt DP requirements.
Design pressure requirements can vary based on product location on the building, height of the building, density of buildings, and wind zone designation. The positive DP number is the standard for wind blowing at the building (windward) and the negative DP number represents the vacuum pressure on the opposite side of the building (leeward).
All Western Reflections doorglass products (decorative door glass, clear door glass, enclosed blinds) with SS, SST, FiberMate®, FiberPro®, and severe weather frames are certified to meet 2010 Florida Building Code DP requirements in 1 and 2 story buildings. Non-impact doorglass, depending on door slab and configuration, have DP ratings from ±60 to ±80. Refer to ODL/Western Reflections' FBC Product Approval FL15260 for specific model numbers and associated DP ratings.
Transoms have a +80/-130 DP rating for rectangular shape; +100/-130 DP rating for curved shapes, and meet code requirements for fixed windows. Refer to Western Reflections' FBC Product Approval FL4554-R3 for further details.
Vent door lights with screen assembly have a ±60 DP rating. Refer to Western Reflections' FBC Product Approval FL14440 for further details.
