Point thermal bridging
WebFeb 15, 2024 · Thermal bridges, also known as cold bridges, are weak points (or areas) in the building envelope which allow heat to pass through more easily. They occur where materials which are better conductors of heat are allowed to form a ‘bridge’ between the … WebAn element-based thermal transmittance associated with a discrete element that penetrates the building envelope.Examples of point thermal bridges include a beam penetrating a wall, a column penetrating a roof or floor, and an anchor or connection used to attach an element to the building and not otherwise addressed as a clear field thermal bridge or linear …

U-value calculations for planar elements should … WebThermal bridging at interface details, such as slabs, parapets and glazing transitions, can be sources of significant heat flow through the building envelope. This transferring of heat through the envelope of the building results in energy reduction as heat flows through the thermal barrier.
WebApr 15, 2013 · Thermal bridging is one reason you can’t blindly judge insulation based on its R-value. Standard wall assembly construction (at least in the Northeast) consists of drywall on 2×6 studs, 6-inch-thick fiberglass batts within the wall cavities, plywood or OSB sheathing, Tyvek building wrap as a water control plane, and siding.
