Greensboro, NC - May 2nd, 2007 - DP 40 is the design pressure rating that Endura's Force 5 Door System is certified, lab, and now field tested to meet the requirements.  Field tests, where equipment and set up are variable, can expect performance to be less compared to a lab test.  However, field testing in the Pacific Northwest gave a result consistent with lab testing.  Endura Products was pleased to work with a well-known Pacific Northwest builder on independently testing their 6/0 wide by 8/0 tall French Therma-Tru panels with the Hoppe enhanced Endura Force 5 system. 

Endura's Force 5 Warranted System is designed and tested to the highest water resistance rating attainable, combining Endura's components with customer door panels that are assembled and installed according to Force 5 specifications.  Force 5 System components have been precisely engineered to work together from the ground up.  The parts have been strenuously tested to ensure excellent quality and durability.  Endura's Force 5 Dealers have been certified to properly assemble and install these door systems.  This guaranteed entry door system provides the customer with long-lasting performance against air and water infiltration in their entry doors.

During this field testing in the Pacific Northwest, Endura's Regional Manager and two Product Engineers were on-site.  A well known independent lab performed the testing and had two technicians present along with a few of the builder's customer service staff.

Endura's system with Therma-Tru door panels yielded two results of 2 passes at DP 27, which is considered the equivalent to a lab tested DP 40 rating.  The system was then tested for a full cycle at an actual DP40 and also passed.  The DP (Design Pressure) rating is based on the air and water resistance.
