OVERVIEW

Y Porth Mawr (the East Gate) is part of Caernarfon’s medieval fortifications, formerly housing the borough’s Exchequer. Cadw, the Welsh government's historic service, commissioned conservation architects Donal Insall Associates to oversee repairs and improvements at the site.

WHAT WE DID

We fitted a total of 16 secondary glazing units. The unusual shapes of the windows required considerable thought and adaptation. The glazing design featured multiple cuts and glass with extrusion bending to achieve a flawless match with the original windows.

THE RESULT

The client has noted significant thermal gains and lower heating bills as a result of the installation.
