Like any modern joinery our windows come in all shapes and sizes: large, 4.5m by 3.6m; small, 0.5m by 0.3m; or irregular, 4.2m by 1m.
As with doors, and other external-facing structures, windows are constructed from only the strongest and most durable species, including: European Oak, a favourite in Sussex; Douglas Fir; Iroko, which is similar to Oak; and Sapele, a sub-species of Mahogany or un-sorted Redwood; a joinery quality Redwood Pine.
All windows must conform to strict regulations on their U-value, a measure of heat transmission through a building surface; to ensure the best performance, thicker double-glazed units and weatherstrips are often incorporated in the design and construction. This is, of course, unless you live in a conservation area or your property is listed, in which case local planners will often determine aesthetics to be a higher priority than heat insulation. A window feature known as leaded lights - where small glass panes that are fitted between lead strings - has recently experienced a resurgence and can be produced in a range of designs and styles. Although the effect can be stunning, your view may be somewhat obscured. A novel idea is to create etched or sand blasted designs in the glass that do not cloud views in the same way.
There are a multitude of window styles on offer, so we’ve listed a few of the most common:
Casement, the standard hanging Sash window;
Stormproof, a modern style of Sash window;
Frames for Crittall frames, a metal alternative;
Direct glazed, a version of Sash window that cannot open;
Box-sash, a traditional style based opened using internal pulleys and weights;
French casement, including vertically curved interlocking rails;
Bay windows, curved / segmented in the plan view;
Bow windows, curved in the vertical plane;
and Yorkshire lights, horizontal sliding sashes found in older properties.
As with doors, ironmongery is an important element in any window: many finishes can be supplied, including brass, chrome, stainless steel, and wrought-/handmade-iron fastening
