The THERMOMASS system, available from Composite Global Solutions is specified with both the insulation component as well as the connectors that hold the two layers of concrete sandwich panels together.
Made from a fibre composite possessing the same thermal properties as concrete, THERMOMASS proprietary patented connectors expand and contract at the same rate as concrete.
Conventional plastic connectors that expand at different rates, put pressure on the concrete during the diurnal cycle, and cause the concrete to crack and spall. This leads to an unattractive appearance, and very importantly, dangerous consequences. The Building Code of Australia or any concrete peak body documentation does not have a section covering the use of connectors in sandwich panels.
In use in Australia, the US and Europe for over 30 years, THERMOMASS insulated concrete sandwich panels come with third party documentation and testing process that proves the strength, durability and thermal properties of the THERMOMASS connectors.
Steel connectors transfer heat from the outside of the building to the inside through thermal bridging. Independent testing shows that heat travels down these connectors and forms hot/cold spots on the interior wall, reducing or nullifying the effectiveness of the insulation layer.
However, THERMOMASS connectors are non-conductive, allowing the panel to protect the R-Value of the insulation layer.
Building with concrete without THERMOMASS connectors can lead to higher energy use, risking the building’s lifespan, the money invested and the safety of the occupants.
