Glass and Glazing Type


Single Glazing

We can manufacture windows that a been glazed with either standard clear annealed glass as well as patterned, textured and opaque glass. Safety and security glass is also available options. Each pane of glass will be cut individually to size and secured into the solid astragals  using traditional putty or timber beads.


Heritage Double Glazing

Traditional glazing check and solid astragals in the sashes with the added benefit of double glazing. We can manufacture sash and case windows with heritage slim double glazing, this style of double glazing is considerably narrower than conventional double glazing with a 8mm sight line (seal around the edge of the unit). that sits neatly into the astragals glazing check. The preferred overall thickness of the unit is 12mm which would incorporate 4mmouter pane / 4mm argon cavity / 4mm inner pane with low emission coating. (These units may also be made with a6mm cavity). We can secure the heritage slim double glazing with either traditional putty or angled timber glazing beads.

Sash and Case Windows

Traditional timber Sash and Case windows have been one the most predominant window style in Scotland since the late 17th Century. This window design is simplistic in operation and is generally low maintenance. Even over the last 400 years the general design and appearance of this window hasn't really changed, the only  discreet changes have been made to suit modern requirements such as adding draught seals and increasing the glazing check to allow the sashes to be suitable for double glazing.  


All our Sash and Case Windows are manufactured in a dedicated, production style workshop, by a highly experienced team of Joiners. who can manufactured windows in either boxed, angled and curved styles, suitable for single glazing, double glazing and heritage slim double glazing. We provide all our customers with superior quality, made to measure sash and case windows, which have been specifically manufactured to your requirements and specifications.

Timber Options


Our customers most popular timber choice is redwood, we manufacture our windows from the highest quality timber available, the pulley styles are produced from a part of the tree known as the sideboards. These cuts of the redwood tree are low in timber knots and shakes in the redwood improving sash and case windows stability. Redwood windows will last a lifetime if the are cared for properly.


Some clients also prefer to have their windows manufactured with a redwood case and sashes but upgrade the case sill and sash bottom rail to meranti hardwood.


We can also manufacture from other types of timber such as Douglas Fir and Oak.

Trickle Vents


We use a recessed trickle vent which sits flush within the timber of the top sash when closed. Outwith building regulations we would generally recommend trickle vents to be used in house hold areas such as

Kitchens and Bathrooms areas, where ventilation may be required.


Double Glazing

Retaining the traditional appearance but increasing the glazing check in the sashes allows us to manufacture sash and case windows with heat retaining double glazed units with a 12mm slight line (seal around the edge of the unit). The preferred overall thickness of the unit is 18mm which would incorporate 4mm outer pane / 10mm argon cavity/ 4mm inner pane with low emission coating. To replicate the astragal detail of the sash windows we use a combination of back to back spacer bar and plant on astragals. This gives the illusion of individual panes of glass and is secured with angled bead.


Staind Glass

We can carefully remove your original stained glass and seal it within your new double glazed unit. Respectfully maintaining the original appearance of your property whilst adding the heat retaining benefits of modern glazing.
