Opening layout
Side-hung, top-hung and fixed sections can be combined around ventilation, access and elevation requirements.
Timber windows
Flush casement windows with quiet, traditional proportions.
Purpose-made timber casement windows in which the opening sash sits flush with the surrounding frame, creating a restrained appearance suited to traditional and contemporary architecture.
Made to order
A calmer frame line
Opening and fixed sections are coordinated to keep the elevation visually balanced.

From Accsys, against rot and decay
Traditional simplicity depends on disciplined proportions.
Flush casements can appear understated, but the relationship between opening sashes, fixed lights and glazing bars requires careful control.
Farrar can develop the layout around the architecture, required ventilation and practical use of each room. Cills, mullions, glazing patterns, colour and hardware are considered together.

Design principle
Opening sections should remain visually coordinated with fixed panes.
A traditional form developed as a complete system.
Flush casements must combine clean sightlines with suitable weathering, glazing and operation.
Opening and fixed lights designed as one composition.
Frame, mullion and glazing-bar positions are coordinated so functional openings do not disrupt the architectural rhythm.
Flush external appearance
Coordinated fixed lights
Property-led proportions

Purpose-made timber frames with opening sashes designed to sit flush within the external frame line.
Opening and operation
Side-hung, top-hung and fixed configurations can be arranged around ventilation and access requirements.
Glazing
Project-specific glass selected around pane size, thermal, acoustic, safety and visual requirements.
Finishes and hardware
Factory-applied coatings and coordinated casement hardware selected for the architectural direction.
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.

Initial guidance for homeowners, builders and project specifiers.
It describes an opening sash that sits flush with the surrounding external frame rather than projecting beyond it.
No. Their clean frame line can suit traditional renovations and contemporary homes, depending on the chosen proportions, glazing and finish.
The layout can be developed to coordinate their visible sightlines, although operating requirements and hardware must still be accommodated.
Glazing patterns can be developed around the building, subject to the final glass, frame and planning specification.
