There are 4 main types of new or replacement casement window available. These are now explained in more detail below.

Bespoke Replica Casement Windows

 

If you’re going to the expense of fitting a new or replacement casement window then you might as well do the job properly. The bespoke nature of our workshop which manufactures with the traditional method of one man – one job, with all timber being machined to size on site, allows us to produce perfect replica casement windows. However, simply making a replica casement window will not suffice if you wish to maintain a perfect period look.

There are 3 key elements that need to be considered when manufacturing and fitting a new or replacement replica casement window. Only when all of these 3 elements; External positioning, casement window composition, and internal finishing are taken fully into consideration, is it possible to fit a window that looks like it’s been there since the property was originally built.

 

External positioning

Prior to 1709 windows were positioned in line with the external, usually timber, face of the building. However, after the great fire of London this was seen as a fire risk and hence the London building act of 1709 decreed that box sashes should be set back 4 inches from the face. The building act of 1774 further developed this by stating that sash boxes must be positioned behind the masonry. One result of this legislation was that many casement windows were positioned behind the brickwork. However, from circa 1900 onwards it became fashionable to position Casement windows in-line with the brickwork. When replacing an existing Casement window it is essential that the original positioning is maintained. This is relatively straight forward when replacing the original casement window, but can be more challenging when reinstating casement windows into an opening that used to have a casement window but perhaps now has a uPVC casement for example.

For new windows it is important that the new opening is created in keeping with the rest of the property. Stone sills and lintels should be matched, proportions should be maintained and the casement window positioning should match any original windows. At joineryworkshop.com we work with various stone masons and quarries to ensure that any new window openings look just like the original ones.

Casement Window composition

We measure the top rail height, style width, bottom rail height, bottom rail angle of chamfer, glazing bar width, visible face, frame depth, sill profile, etc., all to make sure the replacement casement window is a true replica of the original. We even scribe the inner mould.

It is our attention to detail when manufacturing a replica that really sets us apart from other companies.

Internal finishing

Most period casement windows are box lined with a surrounding architrave and stub cill on the inside. Any new or replacement windows should be finished internally in an identical manor if the original period look is to be maintained. Profile matching the design of your original architrave and stub cill is an essential part of achieving this.

 

Mock Sash Casement Windows

Sometimes a clients budget will not allow for sash windows. In this scenario a mock sash casement window can be a more cost effective alternative.

Casement Mock Sash Specification

  • The top  pane is a top hinged, opening stormproof sash, with horns. The horn profile can be made to match your existing windows if required
  • Bottom pane is glazed directly into the frame
  • Sill manufactured to suit brickwork positioning
