WTC Technical Updates

WTC staff have produced several technical updates which may be of interest to the Weatherization network. The goal is to keep the network informed about methods and techniques, and offer decision-making tools which effect health, safety, and energy efficiency in Weatherization. More updates are always in the works. Please consider writing one for us.

Knob and Tube Report

During the summer of 2002, the Pennsylvania Department of Economic and Community Development (PA DCED), the Weatherization Training Center (WTC) at Penn College and STEP Inc., a Weatherization Assistance Program provider, entered into a joint research project. Its purpose was to attempt to identify simple and cost effective wiring retrofits and prescribe safe methods for installing thermal insulation where K&T wiring exists. The recently released report, Retrofitting Knob and Tube Wiring, An Investigation into Codes, Wiring Practices and Cost, provides the results of the project.
