Washer and Bushings using Armatherm™ Thermal Insualtion 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.
