Parapet Roof Penetration Thermal Bridging Solution

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 making 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 percent in these areas.
