Traditional English timber sliding sash windows, which look just like the original windows yet meet the new compulsory standards.

SASH WINDOWS

 SASH SASH

Sash Windows
Choice of Look
Timber Sash Windows - Straight Slider  The traditional vertical straight sliding window has been made for the last 300 years or more, in our window however, we have two modifications. One is that the sashes are operated by spiral balances as opposed to weights and pulleys, although these can be incorporated if required, (Albeit at an additional cost). The other is that we have applied up to date technology and design to the seals, on both the weatherproofing and sound insulation. The sashes are secured with a solid brass Fitch Fastener.        
Timber Sash Windows - Standard Mock  The standard mock window is a top opener over a fixed pane. It is basically a traditional storm-proof casement window, but with sash-style handles retained in order to give the appearance of sash window.The sash is hung on solid brass hinges and operates on a traditional casement stay. Locking facility is by way of a staylock.        
Timber Sash Windows - Superior Mock  The Superior mock window is a top opener over a fixed pane, but with similar traditional sections as would be supplied with a Vertical Straight Slider.The bottom section has a dummy sash (fixed), the top opens outwards on stainless steel friction stays and is secured by a brass locking casement fastener.        
Timber Sash Windows - Slide & Tilt  The Slide & Tilt window is the same as a vertical straight slider, but with tilt-in facility, primarily for cleaning purposes. This is only manufactured with spiral balances, operating within an aluminium channel.The sashes are again secured by a solid brass Fitch Fastener. Traditional handles cannot be an integral part of the sashes as they would impede the operational function of this window. We can however attach dummy handles.        
Timber Sash Windows - Vari Vent  The vari-vent window is what we consider to be the jewel in our crown. This is a window which we have designed and developed ourselves. To our knowledge we are the only company in the world that manufactures this window.Primarily it looks like a vertical straight slider, but for ease of use and to obtain maximum ventilation the top sash opens outwards on stainless steel friction stays while the bottom slides vertically and tilts inwards. The bottom sash is fitted with two 100mm brass slide bolts so that the bottom sash can be secured whilst the top sash is open. When completely closed, the sashes are secured by a brass locking casement fastener.        
Why timber? Timber is the best material for character, warmth, comfort, durability, window/door construction and heat retention. The main timber available: oak (used for sills and also as building material for windows), pine, mahogany, and larch. We use laminated triple-layer wood supplied from FSC approved timber supplier. Three layers are used because this technology prevents the window frame from twisting and increases the lifetime of the windows. The outer layers are radial or half radial cut and this method protects window surfaces from wood cleavage. Security features of sash windows

Timbers & Finishes Depending on your requirements we are willing to leave the products we supply untreated, coated with a base coat or completely pre-finished. Traditionally we use a waterbased coating, which is spray applied to ensure a more durable and professional finish. For added protection the coatings are resistant to U.V. light and they are of course microporous. Although we spray apply our waterbased coatings, they are also available in brushing formulation which ensures an exact match can be obtained on site. We use finishes supplied by Sikkens. If however you require a different finish we would be happy to accommodate your needs.
Highlights
  • These sliding sash windows are suitable for replacements in historic listed buildings or in conservation areas. Modern sash windows are also available for new contemporary buildings
  • Original sash windows consist of two glazed sashes, which slide vertically in a timber frame, supported by cords that are balanced with lead weights. In windows with spiral balances the sash can slide and tilt.
  • Box sash windows usually have thin glazing bars, decorated with oval or lambs-tongue mouldings, and shutters were often positioned either side with similar detailing to provide security or warmth.
  • These windows are usually built from wood and are painted. In our-range of colours there is a choice of opaque and translucent, selected from the Sikkens colour palette.
  • They are double - glazed. The internal double-glazing makes them extremely difficult to break into. They are also glazed from the inside, which means the glazing cannot be removed from the outside.
  • We fit high quality balances: spiral and weights supplied from "UK Balance" and "Mighton". In addition we can supply a range of linings, window boards and architraves in matching material.

Balances and Accessories
Type D Balances These are light duty, economical general purpose balances for domestic or commercial applications. They are manufactured in three weight groups suitable for sashes having glazed weights of up to 18.15Kg (40lbs) and service hatches up to 6.8Kg (15lbs). All 'D' type balances are adjustable within their weight range to suit actual glazed sash weights. A special adjustment tool is available. Where maximum assisted lift is necessary it is advisable to use 'F' type balances when sash weights exceed 17Kg (3.5lbs). Type F,K and M Balances These are heavy duty balances, purpose-made to suit actual sash weights. They incorporate a mechanical feature which, using a screw driver, allows for fine adjustment to be made on site, thus achieving accurate equilibrium with the sash. Subsequently, minimum effort is required to lift heavier installations. These balances are particularly recommended for retirement homes, hospitals or nursing homes.
