Windows
Mock sash windows
The proportions of a traditional sliding sash, made as a simple top-hung casement that is easier to live with and kinder to the budget.
Windows
Sash style, casement sense
A true sliding sash has two frames that pass one another vertically. A mock sash borrows the look, a tall window divided across the middle with the upper pane set forward of the lower, but opens on ordinary hinges. From the street it reads as a sash. In use it behaves like a casement.
That means a tighter weather seal, simpler hardware and a lower cost than a full sliding mechanism. For many period homes it is the most practical way to put back the character that flat, featureless replacement windows took away.
True to the house
Tall proportions and a horizontal meeting rail that follow the lines of the originals.
Traditional details
Georgian or astragal bars and decorative horns can be added to complete the look.
Seals like a casement
Compression gaskets all the way round keep out draughts and rain.
A-rated glazing
The same glass and thermal performance as our standard casements.
Getting the proportions right
The eye is very good at spotting a window that is nearly right. We set the position of the mid rail, the width of the bars and the depth of the bottom rail to suit the house, so a row of new windows lines up with the neighbours and with the brickwork around them.
Glazing bars can be arranged in the classic patterns: six over six for Georgian fronts, two over two for Victorian terraces, or a plain one over one for Edwardian houses.

Questions
Good things to ask
Straight answers to the questions we hear most about this product.
Does a mock sash window slide?
No. It is designed to look like a sliding sash but the opening part is hinged, normally at the top. This gives a better seal and simpler operation than a sliding mechanism.
Is a mock sash suitable for a listed building?
Listed buildings usually require like-for-like timber sliding sashes and listed building consent for any change. A mock sash is better suited to unlisted period homes. If in doubt, speak to your council's conservation officer first.
Can the bars be on the outside of the glass?
Yes. Astragal bars are bonded to the outer and inner faces of the glass with a spacer between, giving the appearance of separate panes. Georgian bars sit inside the sealed unit and leave the glass smooth for cleaning.
