Presented at Building America Experts Meeting – Interior Insulation Retrofit of Mass Masonry Wall Assemblies
Location: Westford, MA
The objective of this program is to explore numerous methods of retrofitting foam insulation on the interior of mass masonry walls. When this is appropriate is the subject of another discussion. Materials options, delivery systems, and strategies for energy performance, reversibility, durability, vapor control, and water management will be demonstrated in various applications.
General Topic – “internal insulation of mass masonry”
Specific topic – “projects and lessons learned”
Provide a collage of examples of “internal insulation of mass masonry” in single-family, multi-family, and institutional projects
Illustrate installations using a number of material types
open and closed-cell foams
stressed-skin foam panels
various membranes and coatings
Demonstrate a number of delivery systems and methods
injection, spray, air sealing
assemblies including stressed-skin foam panels
Show a number of application types
open and closed cavities/surfaces
above-grade interior masonry retrofit strategies
with and without drainage provisions

Participants will be able to select the correct polyurethane foam product and installation method for their specific projects.
Participants will be able to identify the building science issues related to the use of foam plastic.
Participants will be able to differentiate between open and closed-cell foam products.
Participants will be able to relate their projects to similar real-world case studies demonstrating installation methods and foam uses.
