The roof is part of the building envelope where penetrations such as davits, anchors and supports for dunnage extend through the thermal envelope and roof insulation creating non-continuous insulation. These interface details are typically connected to interior trusses or structural elements creating a thermal bridge and point transmittance (heat flow). The R value of the roof can be reduced by up to 40% in these areas.
A structural thermal break at these locations will improve the U value of the roof assembly and prevent potential condensation problems at the structural connection. Armatherm™ FRR and 500 series thermal break materials can transfer the loading conditions at these locations while significantly reducing heat flow, creating continuous insulation. The heat loss can be improved by as much as 80%.
