Glazing patterns
Pane divisions and glazing bars can be developed around the age, style and proportions of the elevation.
Timber windows
Sliding sash windows, made with period character and modern assurance.
Bespoke timber sash windows designed around the proportions of the building, combining traditional visual character with carefully considered glazing, finishes and operation.
Made to order
Built around the elevation
Glazing patterns, meeting rails and frame dimensions are developed together.
Bespoke sash proportions
Purpose-made for each project

50-year timber warranty
From Accsys, against rot and decay
The character of a sash window lives in the details.
A successful replacement should preserve the rhythm and refinement of the elevation rather than appearing visibly heavier or newer.
Meeting rails, glazing bars, horn details, cills and frame sightlines all affect the result. Farrar's purpose-made approach allows those elements to be reviewed together instead of forcing the property around a standard size.

Design principle
The whole elevation should be reviewed before individual openings are finalised.
Period character with present-day expectations.
Appearance, weather performance, glazing and operation must be considered together. The final specification is developed around the building rather than a generic product label.
Sightlines that feel appropriate to the building.
The relationship between the frame, meeting rails and glazing pattern is reviewed across the elevation so replacement windows remain visually coherent.
Period-sensitive proportions
Coordinated glazing bars
Elevation-led design

Sliding sash specification at a glance.
Every project needs a confirmed technical specification. These are the headings we work through with you before manufacture.
Request technical informationConstruction
Purpose-made timber frames and sashes developed around the opening dimensions, elevation and required visual details.
Opening and operation
Opening and balancing arrangements are selected to suit the product design, access requirements and intended use.
Glazing
Glass specification is confirmed around thermal, acoustic, safety, appearance and planning requirements.
Finishes and hardware
Factory-applied coatings and sash furniture are coordinated with the chosen design and maintenance requirements.
Warranty and maintenance
The Accoya timber carries a 50-year manufacturer's warranty against rot and decay. Factory-applied finishes need a maintenance coat after around eight years on average, and at least every five years in exposed locations.

Accoya is the timber behind the 50-year warranty. These cover how it performs and why it is specified for external joinery.

Initial guidance for homeowners, builders and project specifiers.
Purpose-made manufacturing allows frame dimensions, meeting rails, glazing patterns and other details to be developed around the property.
Glazing options can be considered alongside frame sightlines, weight, safety, thermal and acoustic requirements.
They may be, but acceptance depends on the property, local guidance and the proposed details.
Photographs, approximate dimensions, elevations, quantities, location and any known planning requirements are useful starting points.
