Cladding Attachment Solutions For Exterior Insulated Commercial Walls

The use of exterior insulation installed outboard of wall sheathing is becoming increasingly common across North America to meet new energy code requirements.

Commonly referred to as exterior insulation, this insulation is installed continuously on the outside of the primary structure and is typically more thermally efficient than insulation placed between studs or inboard of the structural system, provided that thermally efficient cladding attachments are used.
