Project summary

Mark Wille, Aron Jones, and Joe Konopacki review the assembly details of Shaun St-Amour's latest basement.

The project is part of Clay Construction Inc.'s high performance work.

Construction details

• Insulated Concrete Forms (ICF) are used for the basement.
• ICF provides superior insulation and structural strength.
• A Stego membrane is used as a durable vapor control layer.
• The membrane is intended to prevent moisture infiltration.
• The team will seal gaps and joints in the foundation and walls for air sealing.

Expected performance

• Well-insulated basement space.
• Energy-efficient basement space.
• Moisture-resistant basement space.
• Improved indoor air quality.
