The Wi System is a deceptively simple, yet extremely versatile alternative to traditional windposts and lintels.  It is a method of providing structural support to masonry panels subject to lateral load and can allow the uninterrupted construction of “oversize” blockwork walls with unrestrained lengths of 11m and heights of 8m.

Hollow column and trough blocks allow the construction of integral reinforced concrete columns and beams within the blockwork construction, which eliminate the need for traditional windposts or lintels. This novel approach leads to significant improvements in the structural, acoustic, air permeability and fire resistance performance of the wall panels compared with the use of traditional windposts or lintels. The Wi System also indisputably leads to the most aesthetic finished appearance of structural blockwork walls.

Key benefits
  • 20% saving on construction costs vs SHS wind posts and like for like on angles (WP2s)
  • It’s safer – Eliminates large plant & lifting operations
  • It’s quicker – Logistically far simpler. Can be built in parallel with rest of wall. Fewer operatives required
  • Simplified, more robust fire, acoustic, thermal, and air permeability details
  • 4 hours fire rated – No fire boarding and 50% fewer joints = Large savings across the package
  • Increased overall quality – Fewer details means higher quality and easier to manage
  • Up to 23.6% Carbon Reduction through delivery and manufacture – Can be used toward BREEAM points
  • Aesthetically pleasing as single substrate
  • 2-3 day lead time on all materials
  • Provides maximum versatility during design and construction
  • Single source trade – removes risk by keeping all activities with one supplier
