Manufacturer Reference

System Performance

REHAU-published benchmarks for the system. Results vary with size, configuration, glass, reinforcement and hardware.

System performance benchmarks
Structural (NAFS)Up to CW-PG100
Acoustical (ASTM E90)Up to STC 40
U-value — simulatedDown to 0.17

REHAU webpage benchmarks. The April 2020 sheet instead lists CW-PG70, simulated thermal value 0.18 and OITC 34. These are different published summaries, not a single tested Morrison assembly.

Thermal figures are reproduced in the manufacturer's published notation; confirm units and the exact assembly report before specification. STC and OITC are ratings, not guaranteed reductions in site noise. These summaries do not establish code, impact or Passive House compliance for an order.
