• 1930’s – Steel Replacement Windows

    1930's Homes - Elegance & Versatility

    Benenden windows are the ideal replacement for metal casements commonly fitted on many 1930’s properties. The slim lines of our unique frames preserve the building’s original character, whilst delivering all the benefits you expect of modern aluminium double glazing. Customisation is possible with a range of handles and a comprehensive choice of colours for interior and exterior finishes. We can reproduce leaded and Georgian styles sympathetically. Where authentic leaded lights are required for conservation reasons, this can be achieved with the Benenden Series 1 single glazed option.

    Wherever timber beams are prominently featured, the subtle incorporation of Benenden windows ensures that your home’s character is not lost. With the right choice of colours and window furniture, the ambience is maintained inside and out. Antique lead designs can also be replicated. In many cases only the metal sashes need replacing – leaving the original timber frames in situ removes the necessity for costly redecoration. Where new timber frames are required, we can reproduce the original profiles and match the material and colour finish. A truly bespoke service
