Eliminating Moisture: Window Installation in Exterior Insulated Walls

Scott Tirrell

Architectural Consultant, LEED AP BD + C, FMPC

Pella Corporation - Scarborough, ME

Session Description 


Proper integration of fenestration products into the building envelope plays a critical role in managing moisture in any wall assembly. The addition of exterior insulation in today's energy efficient buildings can make this challenging. We'll look at the impact exterior insulation has on water managed installation design and evaluate options for meeting the requirements for proper window installation in exterior insulated walls including: blocking, exterior extension jambs, and support brackets. Discussions will cover the evolution of wall construction through time and identify the benefits and variations of exterior insulation.

Any professional in building design, construction, management, or ownership will benefit and will leave with a better understanding of the role proper installation of windows in exterior insulated walls plays in a healthy and energy efficient building.
