Diagnostic Approaches to Weatherization
Participants will learn the principles of air leakage and how houses perform as influenced by pressure differences caused by increased air tightening, mechanical exhaust devices, and moisture movement. Includes classroom and lab work associated with equipment set up procedures, field analysis for finding and measuring air leakage using the blower door, methods to determine minimum ventilation guidelines, and advanced techniques using pressure gauges to determine potential for back drafting, pressure balancing of duct work on forced air distribution systems. (16 HOURS). PA WEATHERIZATION SUBGRANTEES AND THEIR CONTRACTORS ARE ADMITTED AT NO CHARGE, SELECT THE SECTION WITH $0.00 COST. (SELECT "OTHER" UNDER PAYMENT OPTIONS).
