Allan Brothers launches Heritage timber window collection for period properties

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 windows and matching flush casements, providing a sympathetic solution for historic estates where different window styles appear across buildings and elevations.

Each window style is made to measure from redwood or red grandis and crafted to replicate the proportions of the original windows.

Traditional features include a 40mm mid-rail on the sliding sash, hand-applied 9mm external beading to mimic historic putty lines and slim-profile double glazing (14mm) designed to resemble historic glass with a ‘single reflection’. Solid 24mm through bars also provide the authentic appearance of individual panes.

Each design can be refined with different glazing configurations to suit Georgian, Victorian or Edwardian architectural styles. 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 involved 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 our designs. For historic homes that have sash windows at the front and casements at the back, our range offers a consistent level of quality and craftsmanship across both styles, which can also help ease the planning process.”
