Rainscreen & Insulation Installation in One

VC was designed to meet even the City of Vancouver’s stringent energy code standards and can be used in 2x4 or 2x6 construction. The product helps meet the Vancouver Code, R22, in a typical 2x4 wall system (BC Energy Step code 1-3+) as well as made to meet R27 to R28 in a typical 2x6 wall system (Step Code 4-5+).

How else can Vertibreak® help your project?
  • Long Term Successful Cladding Attachment with most common claddings Confirmed in 3rd Party Deflection testing.
  • Use of exterior insulation can move the dew point resulting in less condensation, mould & rot.
  • Veritbreak 4 & 6 are 'semi-vapour open'(semi-permeable) so that potential moisture vapour has some ability to escape from walls.
  • Not as susceptible to shrinking, warping, cupping and other wood furring issues which may cause uneven or wavy siding
  • Creates a more robust air barrier when used in conjunction with a taped housewrap system.
  • Individual drainage channels may aid 'compartmentalization' for pressure equalization resulting in less moisture transfer across drainage cavity.
  • Limits the ability for 'ballooning' of housewrap which may otherwise cause tears or air barrier failure.
