Traditional Timber Sliding Sash Windows

Traditional in design our timber sliding sash windows provide the highest level of performance. Our innovative concealed weather seals ensure excellent protection from the elements. Being air tight and discreet they do not detract from the authentic appearance of the window.

For absolute authenticity we provide the traditional cord-and-weights mechanism in the traditional box design. We also offer spiral balance and tilting spiral balance timber sliding sash windows, which have narrower frame profiles to suit more modern reveal constructions.

As is the case for all of our windows, security is intrinsic to design. On all timber sliding sash windows, locking sash fasteners are fitted to the meeting rail. Sash stops are fitted on either side of the frame so that whilst they can be opened for ventilation, the opening is restricted for security and safety.

In all sliding sash designs we use Accoya® timber linings to provide greater durability. In addition we only manufacture external facing astragal bars from Accoya® to provide lasting performance. As standard, the astragal bars are 21mm and fixed into the sash.

For period detailing we have a number of sash horn designs – see the Design tab for more details. We can also provide a wide range of curved work designs, including top arch, internal sash arches and curved fronted windows. Coupled with our vast selection of sash furniture and coating options, our timber sliding sash windows can be designed to exactly match your project requirements.
