Tomeet this requirement builders must have a third partyapproved by their local code jurisdiction complete a blowerdoor test and submit the air leakage results to the codeofficial. This webinar will provide an overview of the generallogistics of completing a blower door test for typicalresidential construction projects to assist builders inscheduling and planning for this mandatory requirement.62

9/24/2018Air Sealing for 5 ACH50 Strategies? Tuesday, November 13 @ 1pm: PHRC Webinar!Air Sealing for 5 ACH50DescriptionPennsylvania’s prescriptive air leakage requirements have recently beenchanged from 7 ACH50 to 5 ACH50. With this change, builders may have tomodify their air sealing package to comply with the prescriptive airinfiltration requirements. In this webinar we will look at areas of concern forair leakage and review several techniques to potential seal those areas.Learning trometrie/permeabilite-a-lair/Review the 2015 IRC and IECC requirements on air leakage.Understand the physical transition of a home with a higher leakage rateto a home with a lower leakage rate and how that change can affect thesustainability of building componentsLearn why air sealing is important to the occupant comfort and healthby not allowing air infiltration from potentially contaminated areasReview air sealing techniques that can help achieve this lowerprescriptive standard.Webinar Overview Getting You Prepared What The Code Says Basics of Air Tightness- Basics of Blower Door TestsYourCompanyYour Site Getting Your Site Prepared- Scheduling- Site PreparationYou Getting Your Company Prepared- Test current homes17Blower Door SetupSet up on an exterior doorAdjustable frame & cover forany size single exterior doorAir pressure gaugeDoorTestBlower (Fan)Fan with adjustable rings fornearly all SF buildingsFan power cord(standard ments-Loans6
