HP Wall System XR

HP+ Wall Systems XR Series

High-Performance Walls for the Future

HP+ Wall System XR Series is a strong structural assembly that complies with codes when built as an air barrier system (ABS). Nominal insulation R-values can range from of R-25.2 up to R-45.8 with 2x4 wood framing. The XR Series offers exceptional energy and cost efficiencies.

HP Wall Systems Series XR

Build Stronger: Create a stronger wall assembly and use less wood than traditional construction.

Build Smarter: Construct a wall assembly that incorporates continuous insulation and an air/vapour barrier system without the need for a conventional vapour and weather resistive barrier.

Build Sustainable: Minimize energy loss with reduced air leakage and high R-values while enhancing indoor comfort.

Systematic Success

The HP+ Wall System XR Series is designed to deliver a smart new way to build affordable, high performance homes.

The wall assembly features the following:

  • 2x6 bottom and top plates
  • 2x4 wood framing at 16"or 24" on center construction
  • 2" Neopor® graphite-enhanced rigid thermal foam insulation. Also available in different thicknesses and R-values to fit your climate zone needs and code requirements
  • MasterSeal® NP1 sealant
  • 2 1/2" WALLTITE® insulating air/vapour barrier material
  • 2" x 4" finished timber girts with 1/2" plywood strips
  • Extra room to add more WALLTITE® for an increased R-value

Strength in Numbers

By combining 2x4 framing with foam sheathing and spray polyurethane foam in a composite design, the HP+ Wall System XR Series can increase structural strength while reducing lumber content and eliminating the need for plywood or OSB sheathing. When properly designed and installed, the HP+ Wall System can offer one of the best values available for residential construction.

Benefits include:

  • Can reduce lumber content by eliminating wood sheathing (plywood, OSB)
  • Wood girts allow WALLTITE to get behind studs greatly reducing thermal bridging and increasing effective R-value
  • Stronger walls with increased lateral resistance compared to a typical wall (studs and exterior sheathing)
  • Improved moisture management that can mitigate thermal and structural issues
  • Mitigate thermal and structural issues; reducing potential builder callbacks

Build a Better Barrier - Thermal, Air, Water and Vapour Drive

With integrated thermal, air, water and vapour flow management in a single system, the HP+ Wall System XR Series provides an effective building envelope against severe Canadian climates.

  • Provides higher thermal performance in 2x4 wood framing and interior square footage without increasing the building's footprint
  • Reduces thermal bridging through continuous insulation which can also perform as a weather resistive barrier
  • Creates a superior air and vapour barrier using WALLTITE and MasterSeal NP1

Tested wall assembly. Increased peace of mind.

The HP+ Wall System XR Series has been tested by third party organizations and evaluated by CCMC.
