Panels:

Various constructed panel variations can be incorporated with the Presto system, and these can be made from steel faced two panel trays, flat steel/plastic sheets or timber panels.

- Fire integrity:

Panels can be constructed to achieve fire integrity. These need to be as a minimum, each wall thickness of 2 mm steel and with a rockwool infill.

As a guide, the panels can be welded to the face of the profiles by slug welding or by crush folding top and bottom to produce a profile flange, welding to the profile in the glazing areas.

- General:

Presto windows are designed to utilize a full range of Forster hinges, which are available depending on choice or application. Hinges are either screw fixed or are welded to the frame.
