Green Deal Cash up Front

No like a velfac window no fixed frame perimeter. They have a single unit with glass and the whole thing opens out the frame is inline set behind the front face.
You have to render first with this window and there will be a gap usually 10mm plus all the way around with a compriband seal recessed inside the reveal gap

Do you set Apu beads up for windows to fit into? The windows are timber/alu clad so need expansion.

No the apu seals to the window frame edge, set your reveal plumb to the bead. The apu weather strip is self adhesive to the frame and allows the difference in thermal expansion between window and the ewi system stopping the crack that forms between the two if the finish ands on the frame allowing water in behind the render finish.

Sto have some vids on the net I believe showing apu and compri tape on how all Ewi systems should be terminated around openings where backwrap is not the spec
