Heritage Sash Window – A 3D render showing the product within a traditional residential context.
Allan Brothers, one of the UK’s longest-established window and door manufacturers, has launched a new Heritage range of timber windows designed for listed properties and homes located in Conservation Areas.
The collection features traditional sliding sash and matching flush casement windows, which together provide a sympathetic solution for historic estates with a mix of window types on different buildings and elevations.
Each window style is made to measure from Redwood/Red Grandis and crafted to mirror the proportions of the original windows.
Traditional features include a 40mm mid-rail (on the sliding sash), hand-applied 9mm external beading to mimic old putty lines, and slim-profile double glazing (14mm) which has the look of historic glass with a ‘single-reflection’. Solid 24mm through bars also give the authentic appearance of separate panes.
Each design can be refined with different glazing configurations to suit the Georgian, Victorian, or Edwardian periods. Property owners can also specify decorative horns and authentic hardware, such as cord-and-weight opening systems on the sliding sash or traditional butt hinges with peg-and-stay on the flush casements.
Morten Bach Valsted, managing director of Allan Brothers, said: "As the oldest manufacturer of timber windows and doors in the country, with literally centuries of joinery expertise at our fingertips, it made perfect sense to use our skills to develop a Heritage range.
“We’re well aware of the challenges faced in replacing windows in older properties, so we’ve spent a lot of time getting the timber details right and finding ways to adapt and customise. For historic homes that have sash windows at the front and casements at the back, we have a consistency of quality and craftsmanship across both styles that can also help ease the planning process.”
