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.

More and more commercial projects are requiring exterior insulation under all cladding materials because it is non-combustible, water ‘repellent’, fire-resistant and sound absorbent.
