Rate of heat transfer in W/m²·K. Lower generally means more insulating.
Residential performance guidance
Plan for comfort. Specify the right performance.
Explore high-performance windows and doors for low-energy homes and Passive House projects. Compare complete configurations—not just a series name.
High-performance options in the expanded range
Morrison’s expanded residential offering includes tilt-and-turn windows and ARTEVO systems. Reinforced profiles, compression seals and coordinated glazing packages support thermal design; the final result depends on the complete unit and its installation.
Passive House certification applies to specified components and configurations. PHI lists Wintegra’s GENEO Passive House window separately from REHAU’s ARTEVO window system. Confirm current availability and the certificate applicable to your proposed assembly; window certification does not automatically cover French doors.
Compare like with like: frame Uf, glass Ug and whole-window Uw describe different parts of the assembly. A frame or glass value is not the complete installed product result. Glazing, spacers, size, hardware, thresholds and installation details all matter.
Existing Morrison QAI-listed configurations
The following planning ranges summarize families listed under W516-1 and W516-3 for evaluation to CSA A440.2. They are not ARTEVO or GENEO certification data. Use the exact model and glass code for final comparison.
Fraction of solar energy admitted by the complete product. The appropriate value depends on the project.
A comparative rating calculated for defined reference conditions; it is not available for every listed configuration.
Do not specify from a range.
The endpoints below come from different glass/grille model codes. They do not describe one unit and must not be combined. Confirm current listing status, exact model code, size, installation and local requirements before ordering.

How these values should be used
QAI notes that specimen procedures do not necessarily establish installed perimeter sealant and anchoring performance; only appropriately marked products are considered listed; the listing is not a warranty; and current status and authority acceptance must be confirmed. Ask Morrison to match the proposed unit to the current listing and model code.
