Exclusive Timberweld® Construction

With identical frame and sash profiles to those found on our premier Symphony product, including the beautiful wood grained, textured acrylic foil on all profiles, Harmony also has a deep bottom rail, continuous run through horns and exclusive Timberweld® construction.

“A rated” 24mm sealed units, filled with Argon gas allow internal Georgian bars and glazing beads, whilst chamfered external bars provide the traditional putty glazed appearance. With fully steel reinforced sashes, security from the exclusive, Acorn or Beehive designed, stainless steel bygone clawed cam catches, means Harmony is fully “secured by design” compliant, the police preferred specification for sash windows.

Window Styles and Key Features

To help you visualise what your new sash windows will look like, we’ve listed some of the more popular window designs to give you some idea of the variety available. The design of the Georgian bar layout changes the appearance of windows, so it’s vital to select those that match your current windows or those that existed previously.

Standard Glazing Bar and Bead

While all our windows are steel reinforced, secured by design and “A rated” as standard, Harmony has our standard 24mm sealed units, (4:16:4mm) filled with Argon gas.

Although this means your windows won’t have the deep bar, they still interlock to form a grille which is firmly attached to the glass surface, with the bar ends being clamped in place using patented, stainless steel Georgi clips.

Externally chamfered sashes and bars provide the traditional, “putty glazed” appearance.

Beautiful and Authentic Victorian Features

When horns became fashionable during the Victorian period, they like the deep bottom rails were made with vertical “mortice and tenoned” joints, the same is true for Bygone Harmony sash windows.

Along with a grained, textured, acrylic wood foil you can be certain that your new sash windows will have a perfect, authentic sash window appearance, because most people when they first touch the highly defined grain, cannot believe it’s not wood.

Whilst the standard offering is white foil, cream coloured foil is also available however if you require something a little more special, then why not consider the contrast of black frames with white sashes, for that matter any “Farrow and Ball” or “RAL” coloured paint you wish to select.

Colour Suited Locks and Recessed Limit Stops

Every Bygone Harmony sash window is fitted with a single or pair, of solid stainless steel cam catches and face fixed keeps. Unique and again patented, a pair of left and right hand cams will centralise large sashes within the frame for better security, but even single cams are attached with three screws so Bygone cams won’t be forced apart.

Every keep is attached with four screws, two for vertical alignment and two horizontally, into steel reinforcing. Each keep is also fitted with a special nylon insert to protect the plated surface of the stainless steel claw.

Again unlike clumsy, surface mounted devices which are fiddly to use, all Bygone sash windows have a pair of recessed limit stops, which are silky smooth and do not protrude from the surface of the sash, until open.
