Timber Yorkshire Sash Windows

Timber Yorkshire Sash Windows

Our horizontal sliding sash window or ‘Yorkshire Sash’ are often seen in cottages in the North Yorkshire area. Their proportions are traditionally square and they open by the inner sash sliding behind the outer on an aluminium track and high quality adjustable rollers, making the sash operation easy and smooth.

As we are a Yorkshire based company with our factory located in Bradford, West Yorkshire, manufacturing this productis part of our heritage!

Design Features


  • Traditional hardware
  • Aluminium track and high quality adjustable rollers
  • Independently tested
  • Guaranteed performance
  • Internal beading
  • Double draught sealed to maximise thermal performance and weather proofing
  • Lockable fitch catch, traditional in its appearance, when closed it pulls the two sashes together to engage the seals fully


  • Concealed trickle ventilation – when required for new build situations our design conceals the trickle vent into the head of the frame, externally the vent is almost invisible and is concealed internally by the head rebate
  • Traditional hardwareavailable in a large range of colour options
  • Vent lock – these devices provide additional security and peace of mind in that the window cannot be opened more than 100mm without them being removed
  • Angel lock – as with the vent lock, this device limits the travel of the sash. The advantage is, when the sash is subsequently closed, the device resets. When the sash is next opened, the restrictor stops the movement of the sash more than 100mm.
Paint Process

first-primer2compressed patchett-joinery-paint-process-compressedUsing only a water-based painting system which allowstimber to “breathe” and adapt to climatic changes, ourfinishes provide maximum protection against weathering,fungal attack and UV degradation. The water-basedapplication significantly reduces harmful emissions anddisposal issues associated with solvent based systems.

Working with our paint partner, Sikkens, we can finish in any RAL colour, stain, or match against all well known paint ranges and brands. With the ability to have different internal and external finishes, your windows and doors can be finished just as you require.

Our factory is audited quarterly to ensure that the finished product has thehighest quality paint finish and performance you would expect.
