We have reproduced the aesthetic appearance of a Traditional Casement window with traditional ironmongery, brass butt hinges, casement fasteners and stays. However, under the new Building Regulations Part L, it is mandatory that all new windows shall comply with a minimum U value and to achieve this we have incorporated double glazing and draught seals to make this window fully compliant.


The timber frame of Casement Windows was developed from heavy oak frames of medieval openings. Jambs, cill and head were jointed with a pegged mortice and tenon. A slimmer softwood version of this contruction forms the basis of the Traditional Casement window.

In a typical window a glazing rebate is formed allowing the glass to be fixed from the outside face and was held in place with sprigs and putty, with the incorporation of double glazing, a glazing tape and bead system must me used if the life of the double glazed unit is not to be compromised. The beading is bevelled to give the appearance of putty pointing. A little sophistication was introduced by means of moulding the inner edge of the frame where it adjoins the glass, the glazing bars being moulded to match, and the fixed frame was often also moulded.

In traditional construction, mouldings meet at mitred corners, they were never routered after assembly, rounding the inner edges, as is common today.
