Revival Windows

Callidus Installations will revive your old worn-out windows, faithfully replicating the period timber style. The shape, sightlines, and timber hardware are matched on every detail, but with the added benefits of low-maintenance and durable uPVC. Revival from PlatinumNRG have taken care of the details, and can even include a working stay and peg, which you can specify to fit your taste.

A step-up from other window frames, this 85mm deep frame is made up of seven chambers, giving even more thermal efficiency and structural strength to the window’s design. This complex insulation is inconspicuous, however, where the appearance remains classic using a deep sculptured edge.

  • 85mm frame
