How to Design and Build High Performance Walls and Roofs

December 6 @ 9:00 am - 4:30 pm

Description

California’s new Title 24 Energy Code all but requires high performance walls with exterior insulation as well as attics and roofs with multiple layers of insulation in what can seem to be in confusing and contradictory locations.

This class examines how to design and build high performance wall and roof assemblies that deliver energy efficiency and do not lead to water and moisture failures.

Steve Easley will use pictures from real world installations to illustrate the do’s and don’ts to building high performance walls and roof assemblies that are affordable and cost effective.  This interactive class is designed to sort through the myriad of insulation system options in order to match the best insulation system to the type of structure.

Energy codes are requiring specific installation protocols to ensure true insulation performance. This class also will explain installation and air barrier requirements by codes in order to develop appropriate specifications to meet these new codes and create buildings that perform with better real world results.

 

 Agenda

Introduction & Safety Announcements

  • Vented verses unvented attics
  • Fiberglass batts & blown, cellulose blown & dense pack, 1-part spray foam, open & closed cell 2-part spray foam, rigid foam board (EPS, XPS, isocyanurate, etc), SIPS
  • Open cell spray foam, what works best where
  • Closed cell spray foam, what works best where
  • Understanding the environmental impacts of foam insulation
  • Safety & IAQ issues (during & after installation)
  • Avoiding common insulation related building failures
  • Fire resistance and code issues
  • Understand mechanisms different types of insulation use retard heat flow
  • Insulation permeability and moisture vapor transfer and condensation
  • New approaches to insulating attics
  • Air sealing and air barriers
  • RESNET’s insulation installation grades 1,2,&3
  • Title 24 and QII

Objective

The objective of this course is that at the conclusion, participants will be able to:

  • Describe how to correctly incorporate exterior wall insulation over wood sheathing with regards to proper water/air barrier and flashing integration.
  • Explain how to design and build energy efficient high performance roof and attic assemblies to reduce the risks of premature roof failures.
  • Select the best insulation system for a given application and write better specifications regarding insulation and installation.
  • Explain how insulation works and sort fact from fiction regarding manufacturer claims.
  • Summarize the relationships between air barriers, moisture vapor transmission, condensation, material permeability, and how these terms relate to selecting the best insulation system for achieving Title 24 requirements.
