Identical frame and sash profiles to those found on our premiere Symphony product, including the beautiful wood grained, textured acrylic foil on all profiles. Every deep bottom rail and continuous run through horn, has traditional, “butt jointed” construction; the others are mitred, providing the perfect appearance.
"A rated" with slim line 18mm sealed units, filled with Krypton gas allow deeper 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.
slender sealed units with extra deep bar and bead
While all our windows are steel reinforced, secured by design and "A rated" as standard, Harmony has slender 18mm sealed units, filled with Krypton gas.
Gas performs far better in narrower units and allows the inside of the window to have really deep astragal bars and glazing bead. Interlocking bars form a grille which is firmly attached to the glass surface, while the bar ends are clamped in place using patented, stainless steel Georgi clips.
Externally chamfered sashes and bars provide the traditional, "putty glazed" appearance.
mitred joints but authentic horns and deep bottom rails
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.
Whilst Acorn or Beehive shaped release knobs and cams are standard options for Harmony, the Porcelain ball design is also available as an optional extra.
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.
