Genesis All-Cellular Window
DH tested DP-50 / Air .08 on the all welded version / .15 on Mechanical Thermal U-.26 / dual glazed, low-e argon… .22 if you use 2 low-e’s Triple available, not yet simulated.
Is there a clip system to hold a casement sash in a fixed position thus avoiding hardware costs to create a fixed window?
Royal 7900 Series
Yes you can punch, we are doing that now / can drill and route too
Frame and sash can be built in a Mortise & Tenon version
Set for 3/4″ and 1 1/8″ any beads in between could be done
Yes, but to be determined
There is a piece of aluminum that screws to the underside of the exterior rail if needed at 44″ x 60″…no reinforcement was needed to get to DP-50
