SashWise fitted new Accoya Double-Glazed sash windows into the original sash boxes which we fully restored, at this beautiful Edwardian detached townhouse in Hampton.

Project scope:

  • Installation of new double glazed sash windows
  • Restoration of current sash boxes
  • Fitting new window hardware
  • Installation of new plantation shutters

Key benefits to the client:

  • Energy and heat saving benefits
  • Enhanced soundproofing from outside noise
  • Improved function of windows
  • Increased privacy
  • Enhanced Security
  • Control over light inside of the home

These modern replica double-glazed sash windows retain the original character of the period building while providing thermal efficiency and a reduction in noise pollution.

The work included restoring the current sash boxes; fitting new traditional ball-bearing pulleys, lead weights, draught-proof beadings and slim-line double-glazed sealed units.

The new sashes windows were completed by these beautiful bespoke Plantation Shutters which were designed, supplied and fitted by SashWise. “Sashwise provided us with an excellent sash window following a major extension to our Edwardian House in 2014.  The product was excellent but possibly more impressive was the service that went with it, from the fitters to the administration.  We then purchased another sash window when we refurbished our guest bedroom.  Then this year  [2016], when we redecorated our master bedroom we asked Sashwise to refurbish 3 more windows. and also 2 sash windows in the lounge.  We are very happy customers and trust the quality of the Sashwise product and the professionalism and integrity of the staff.  We have no hesitation in recommending them. ” – William & Elizabeth Angus. 17.01.2017.
