What is the connector spacing?

Typically, the connectors are spaced 400 mm (16 in) on center in both directions. Depending on panel dimensions and loading conditions, special spacing may be specified.

 

 

How is this spacing achieved in the field or plant?

All insulation boards supplied with the THERMOMASS Building Insulation System are delivered with prepunched holes at the specified spacing. Instructions are available should holes need to be added in the field.

 

 

What does the connector designation mean?

There are two series of connectors: MC (Metric Common) and MS (Metric Short). The MC series connectors have 50 mm (2 in) embedment into both the interior and exterior concrete layers, while the MS series connectors have 38 mm (1.5 in) embedment.

The four digits following the two-letter designation indicate the insulation thickness. The first number is the insulation thickness measured in inches, multiplied by 10. The second number is the insulation thickness measured in millimeters.

For example, an MS20/50 connector would have an embedment of 38 mm (1.5 in) and would be used with 50 mm (2 in) thick insulation.

 

 

How do I determine which connectors to use?

All connectors have a molded collar with a length corresponding to the insulation thickness. The MS serie is designed for panels in which one or both concrete wythes are 50 mm to 63 mm (2.0 in to 2.5 in) thick (minimum recommended thickness). If both concrete wythes are 63 mm (2.5 in) or more in thickness, or if the depth of the reveals in the panels allow a net thickness 2.0 in or greater, then the MC series connectors should be used.
