These are the perfect replacement window for period properties; flush sash or flush casement windows deliver a good blend of efficiency & performance you’d expect from modern windows with traditional styling. The simple classic lines deliver an undeniably authentic look, while the contemporary uPVC frames offer outstanding energy efficiency.
Clean Simple Lines.
Heritage properties have appealing character features that always remain popular through the ages. Unfortunately, though, there are drawbacks of such properties, including energy inefficiencies such as dampness & draughts associated with ill-fitting & single glazed windows. Fitting flush sash windows can overcome these issues often associated with beautiful older houses by providing modern levels of warmth & energy efficiency & reducing your energy bills. uPVC construction also results in a window that doesn’t swell, rot, or warp, while never needing repainting.
Alongside the warmth and comfort achieved by fitting new windows to a period property, sound insulation is also an added benefit. In conservation areas, there is often a requirement for homeowners to replicate original windows closely. The clean, simple lines of flush sash windows make them a suitable option for such houses.
Traditional Styling.
Tailor-made for each property, the windows achieve both a visual & physical fit. With the option to specify different colours for the exterior & interior frames, you can complement your interior colour scheme while attaining a more traditional exterior look.
Impressive security credentials and a ten-year insurance-backed guarantee will allow you to enjoy peace of mind from the outset.
