The precast panels were designed as non-composite sandwich walls, 290 mm thick, with 90 mm of rigid insulation for a total R value of 21. Precast concrete insulated sandwich wall panels provide a functional and aesthetic wall system.
This document provides guidelines for specifying, plan-ning, designing, fabrication, and erecting precast concrete wall panels. Although the focus is on precast wall panels produced in established precasting plants, site precasting is an option that has been used successfully.
Design Tables & Charts. The following sections from the PCI Design Handbook include interaction curves, load tables, and section properties for various precast concrete components. You can access tables from previous editions of the handbook as well as the current edition.
Insulated precast concrete wall panels have all the benefits of traditional precast such as durability, acoustic absorption, and quick install, in addition to the added bonus of being an all-in-one complete
Precast Insulated Wall Panels (PIWPs) have been used in building construction for over five decades1. A PIWP consists of a layer of insulating material “sandwiched” between two wythes of concrete.
High performance precast in-sulated sandwich wall panels can provide significant contributions toward these goals. These panels are com-posed of two wythes of concrete separated by a continuous (edge-to-edge) wythe of insulation.
precast concrete sandwich wall panels commonly have steady state R-values ranging from 12 to 20 hr ft2 °F/Btu. The thickness of the insulation is determined by the thermal characteristics of the insulating material and the thermal loads on the structure.
