HK Composites Connection Ties for Insulated Concrete Sandwich Panels

HK Connection Ties are engineered thermopolymer ties designed to connect two concrete wythes through rigid insulation for insulated concrete sandwich panel systems. Their patented, low-conductivity polymer systems excel in tests for tensile strength, shearing, concrete pull-out, long term alkaline resistance, fire, cyclic fatigue and more. Standard and composite action ties available.

HK ties minimize the energy draining effects of thermal bridging experienced when metal ties or solid sections of concrete are used to connect the concrete wythes of sandwich panels through the insulation layer.

Thermal Mass Effect

thermal mass is a property of the mass of a building which enables it to store heat, providing "inertia" against temperature fluctuations.
 

HK ST Ties

  • AC 320 compliant evaluated by ICC-ESR 3381
  • ST Ties support 2" to 8" insulation thickness
  • Fully fabricated foam systems - XPS, Polyiso
  • More ductile - the ability of the connector to flex with thermal expansion reduced potential cracking & spalling of concrete panel
  • Reduced Lead times: shop drawings, foam fabrication, flat bed delivery direct to jobsite
  • Dynamic R-Values achieved through thermal mass effect
  • 18 year warranty
  • Installation instructions
  • SPECS

HK Double Prong Ties

  • Unique to the industry, ties support 1" and 1.5" insulation board
  • DP ties deflect thermal expansion between two prongs encouraging independent panel flex without spalling or cracking concrete.
  • Fully fabricated foam systems - XPS or Polyiso
  • Reduced lead times: shop drawings, foam fabrication, flat bed delivery direct to jobsite
  • Dynamic R-Values achieved through thermal mass effect
  • 18 year warranty
  • Installation Instructions
  • SPECS

HK Composite Action Ties

  • Designed to create a structurally composite concrete insulation panel - glass fiber reinforced thermoplastic
  • Composite Action means that the two wythes of concrete are acting together structurally thus allowing a thinner panel to be created.
  • Tested in accordance to ICC-ES AC 320
  • Fully Fabricated foam systems - XPS, Polyiso
  • Reduced lead times: shop drawings, fabrication, flat-bed delivery direct to job site
  • Dynamic R-Values achieved through thermal mass effect
  • 18 year warranty
  • CA Installation instructions
  • SPECS

HK Vertical Pour/ Modular Precast Systems

  • Specifically designed for use in vertical pour site cast formwork, precast panels, or modular precast units
  • tested in accordance with the ICC-ES AC 320
  • 2", 3" and 4" ties available
  • Fabricated foam systems - XPS, Polyiso
  • In-place temperature range -40 to 200 F
  • 18 year warranty
