Higher, effective wall assembly R values are achieved using lower values of external insulation. For example, to obtain an R value of R-13 minimum to meet ASHRAE zone 1, steel girts require an external R20, whereas Armatherm requires only R10 which brings massive savings to you. The material is made of a reinforced, thermoset resin that is fire resistant and exhibits very limited creep under load, making it the ideal material for use in structural and façade thermal break connections.
