What is a System U-Value Calculation?

A System U-value calculation involves both the thermal performance of glass and its surrounding framing. Our Window App takes the complexity out of this calculation to provide you with a simple and flexible U-value tool that generates results in a matter of seconds.

What is a good U-value for buildings?

As the demands of the National Construction Code increase, the importance of higher-performance glazing systems is magnified. Moving forward, glazing System U-values lower than 2.0 W / m2.K will be typical, among a number of other improvements, including wall system R-values.

Your Guide Through NCC 2019 Section J

What is a thermal bridge?

Thermal bridging describes a design or construction detail where there is a direct connection between the inside and outside through one or more elements that are more thermally conductive than the rest of the building envelope. Thermal bridges can occur at several locations within a building envelope. Windows and doors, especially frame components, remain a weak point in construction, commonly leading to thermal bridges that result in high heat loss and low surface temperatures on the interior side of the building envelope.

What are thermal breaks?

A thermal break is a material of low thermal conductivity placed in an assembly to reduce or prevent the flow of thermal energy between conductive materials. In glazing systems, thermally broken refers to frame products that have a low thermal conductivity material to avoid unwanted heat loss or gain, and lower condensation risk. Market dependent, thermal breaks of PVC, neoprene rubber, polyurethane and polyester-reinforced nylon are used for improved thermal performance. A thermal break, separating the external and internal framing elements is at a minimum 5.3 mm thick and can be up to 25 mm or more, with the polyester reinforced nylon varieties.
