ICC IECC & ASHRAE 90.1 Prescriptive Opaque Wall R-value Compliance EvaluationĭuPont will verify that thermal insulation specified on the submitted drawings comply with the prescriptive opaque wall R-value requirements for the specified climate zone and code. If submitted drawings do not show proper termination/ties for continuous WRB/AB, DuPont will reference existing solutions and provide guidance to address the discrepancy and/ or provide a custom proposal for special design considerations or highly complex projects. verify transition areas (highest risk areas)have continuous WRB/AB coverage, review every termination of DuPont product. Use of the Design Assistance Package does not confirm compliance with all requirement of any DuPont warranty.ĭuPont will verify that drawings show continuous WRB/AB (i.e. Any comments and observations, mark-up to design details, or illustrations are provided by DuPont to suggest how to incorporate DuPont building products into the project design to achieve compliance with the DuPont Installation Literature.

Drawings must be of sufficient quality and detail for DuPont to effectively perform the review. The objective is to verify the drawings communicate the details critical to enabling high quality installation in accordance with the DuPont Installation Literature. and Installation Information.ĭuPont’s Installation Literature was developed based on extensive environmental testing includingwater and air infiltration testing.ĭupont’s review will examine the sequence of DuPont materials as well as flashing details around penetrations, fenestrations, roof/wall junctures, wall/foundation junctures, etc. With decades of water, air, and thermal experience, our experts know that building envelope protection starts and ends with the details.ĭuPont Installation Literature ConformanceĭuPont to confirm that the technical drawings for above grade exterior walls meeting industry standards submitted by the customer are consistent with the published DuPont Installation Literature, including Installation Guidelines, Installation Bulletins, Installation Instructions, Installation Procedures. To help reduce errors and potential costly rework,DuPont now offers design-phase detailing and technical assistance for above grade exterior walls directly from the DuPont Building Knowledge Center Team. RFIs and rework can add up quickly in terms of both time and cost an estimated 30% of the work done by construction companies is rework, with rework accounting for roughly 5% of the overall contract value. We all know that time is of the utmost importance on the job site. Custom Commercial Building Envelope Design Assistance from DuPont
