For 20 years HK Composites has been manufacturing quality concrete insulated sandwich panel wall ties. With over 25 million sq ft of insulated sandwich panels successfully poured around the world, HK Composites is quickly becoming a well-recognized brand for insulated sandwich panel systems, in both the precast concrete and the tilt-up concrete industries.

As you can see below, HK Composites manufacturers several types of ties (or connectors) for different purposes. If you need help deciding which connector system works best for your project, please contact us today.

About HK™ Composites

HK Composites creates several types of HK Wall Ties for use in insulated concrete sandwich panels. The ties (also known as "spikes" or "connectors") are manufactured from high-performance, heat and alkaline resistant, engineered polymers.

HK ties minimize the energy draining effects of thermal bridging experienced when metal ties or solid concrete sections are used to connect the concrete wythes of sandwich panels through the insulation layer. The use of HK low-conductivity ties results in a sandwich panel with maximum thermal performance.
