Armatherm™ FRR Structural Thermal Break Material

(Thermal Insulation Material - TIM)

Armatherm™ FRR structural thermal break material provides a combination of low thermal conductivity and high compressive strength and has been used in hundreds of structural steel framing connections transferring load in moment and shear conditions. Armatherm™ FRR thermal break material can support up 40,000 psi and has an R value of 0.9 per inch. The material is made of a reinforced, thermoset resin which is fire resistant and has very limited creep under load, making it the ideal material for use in structural steel and façade thermal break connections.

Washer and Bushings using Armatherm™ Thermal Insulation Material (TIM)

With a bolt through insulation pad there is a slight thermal transfer along the connecting bolt.

To further reduce heat loss, Armatherm™  bushings and washers can be used on the warm face of the structure. A thermal break at the bolt connection will reduce heat loss an additional 4% per bolt depending on the wall assembly construction.

In extreme applications (e.g. Indoor Swimming Pools), to prevent condensation on the bolt head, a polyurethane nut cap can be supplied to effectively screen this cold surface from the internal environment.
