What Is CosyWall?

CosyWall™ insulation (CWI) is an external wall cavity insulation system (EWCIS) for wall insulation, providing thermal insulation and acoustical insulation to wall cavities lined on both sides. The CosyWall house insulation system includes:

  • An assessment of building suitability.
  • Licensed insulation installation of water-repellent glasswool insulation.
  • Durable external wall cladding repair.

How does CosyWall Work? codemark_logo Wall Insulation | Retrofit Home Insulation - AAA Insulation

CosyWall is NOT spray insulation foam, expanding foam, or spray foam insulation. It is a DRY spray-in type insulation. CosyWall insulation is manufactured by melting and spinning a blend of inert, natural minerals, similar to Rockwool insulation.

CosyWall Insulation is a formaldehyde-free, non-combustible, water repellent, durable dry blown wall insulation. CosyWall is packed in weatherproof plastic CWI bags. You can get wall insulation NZ wide with Cozy Wall insulation.

The CosyWall in wall insulation system is a multi-purpose product designed to provide effective thermal wall insulation and acoustic wall (soundproofing walls) insulation for existing watertight external timber-framed wall cavities, fibre cement, plywood or sealed masonry veneer claddings.  CosyWall has a Codemark Certificate of Conformity,  as it is proven to be a reliable insulation option.
