Add / Edit Framing

Where a wall, roof or floor system has a repeated structural thermal bridge, it needs to be included to account for the Total R-value of the system. Thermal bridging occurs when a significant difference in thermal conductivity between the materials in a building assembly leads to heat transfer. These bridges can cause heat to escape from the interior of a building to the exterior, or vice versa, depending on the season and the direction of the thermal gradient.

Add Framing

An 'Air Cavity', 'Bridged Air Cavity' or 'Insulation Layer' material layer must be nominated to add a frame. In the example below, an 'Insulation Layer' demonstrates how to add a frame. First, the generic Glass Wool (Wall) insulation product is selected. Next, we select 'Add Framing' to nominate a Framing System. In this example, a 'Steel Stud 92 X 36 mm / 0.75 BMT / 450 mm spacing' is selected under generic materials. You will now

Edit Framing

Once a frame is added for thermal bridging, the thermal performance, area and dimensions can be adjusted. Hover over any bridged material and left-click the material icon in the top left corner. The generic Glass Wool (Wall) insulation product is the bridged material in the example below. Next, navigate to Edit Framing and left-click. You are now presented with thermal performance, area and dimensions, which can all significantly impact the Total R-value of the Wall System, particularly when designing with structural or non-structural steel. Adjust any framing input and then left=click 'Save'.
