The thermally efficient 451PT Framing System was designed in close collaboration with Scape. The system meets the needs of the education, refurbishment and new build markets. The 451PT is also suitable as a ground floor alternative to curtain wall use on commercial projects in the public sector, and is ideal for large display windows in the retail sector.

The system provides slimline, dual-colour and multi-glazed framing modules of varying widths and heights that feature fixed lights, opening vents and insulated panels.
