Box Sash Window: Period
Our sash windows are manufactured from premium, sustainably sourced timber, including pine, sapele, European oak, Accoya, and engineered hardwoods such as Red Grandis.
Additional timber species can be sourced for bespoke applications, subject to availability and suitability.



Box Sash Period frames are designed to accommodate 4mm single glazing.
Glazing bars are available in a variety of profiles, with differing depths and detailing to suit traditional designs.
True solid glazing bars are used within the Box Sash Period range, glazed with a traditional external putty finish.
Popular glazing bars available:
Heritage Victorian lambs tongue 18mm
Heritage Georgian ovolo 18mm
Gothic 18mm
Ovolo 32mm
Queen Anne Ovolo 40mm.
Where required, trickle vents are fully concealed through the head of the frame and are invisible on the internal or the external face of the product.
We offer an extensive range of stains and colours, including any shade from popular paint ranges. If you have a specific colour in mind, we can match it.
Working closely with leading component manufacturers, we carefully select high-quality hardware that delivers both excellent performance and refined detailing.
