Offer up structural cassettes C & D as shown. Ensure the lower faces are supported using props as shown. The critical thing is to make sure the underside of both cassettes are level.   From the top, tap down the hanging bracket tab and secure in place using 65mm round head nails.

Next fasten the angled tie brackets to the cassettes ensuring that it lines up with the mortar joint - the back leg should fit flush to the inner leaf of masonry.   Fix the structural cassettes to the host wall with the 'L' shape brackets provided. Fix at approx 1000mm centres. Note: The number of brackets supplied is dependant on the Orangery specification and varies from project to project.

Slide the long fixing brackets down between the structural cassette and the inner leaf of masonry. Screw fix to the structural cassette. Note: The number of brackets supplied is dependant on the Orangery specification and varies from project to project.   Fix the long fixing brackets to the walls using the appropriate fixings for the substrate.

Using lead, flash over the GRP panels around the perimeter of the Orangery roof. Attach coping stone.   Bond the unsulation panel to the box gutter, then having plaster boarded the soffit and fascia, fit the internal fascia trim by screw fixing through the fascia as shown, ensuring a packer piece is used behind each fixing to ensure the trim isn't compressed. Then add the ultraselect trim.

Now all the masonry is completed, trim the back edge of the hopper to hide the outlet. The outlet is fitted with a capillary groove to prevent water tracking back.   Now it is time to fix the window frames into the masonry. Attach the 'Z' shaped brackets to the frames. Notch the frame rib extrusions first to ensure 'Z' bracket seats correctly.

The frames are now offered into position and the 'Z' brackets attached to the underside of the cassette - they should fit neatly into the pre-rebated pockets in the soffit of the cassette.   Cassette is fixed through the host wall. If the primary cassettes are at 90° to the host wall, a pocket in the host wall is needed. Pack with slate to level and then make good.
