Below is a list of the additional features, finishes and accessories that are available for all of our Sash Windows.

Colour Options

The Sash windows are available in any RAL colour and can be colour matched to Farrow & Ball (UPVc). UPVc are also available in various finishes- such as a plain gloss or white woodgrain foiled finish

Decorative Horns

Add some Decorative Horn detail to make your Sash windows more authentic. Available as
an add on horn effect or a seamless run through horn from the window profile- this is where the window runs into to the horn shape without any additional lines

Tilt-in Operation

The Sash windows are not only equipped with traditional authentic hardware, but they are also incredibly practical and tilt inwards to permit easy cleaning of the external glass

Glazing Bars

Sash Windows can be manufactured with numerous optional bar styles:
Non Bar, Georgian, Half Georgian, Georgian Variant, Single Georgian Bar, Marginal and Asymmetric

Opening Styles

The sash windows can be opened using cords and weights or spiral balance designs. Pulley Wheels are used on sliding sash cords and weights as a lifting mechanism for the sash and are available in Polished Chrome, Brass or Satin Chrome


Many glass designs are available along with the option of Double, Triple or Acoustic Glass. Some of the window frame options also boast A rated energy efficient glass


Colour Options


The colour of windows has a massive impact on the look of any property, so we understand how important it is to select a colour & style that suits the general appearance of your home.  This is why we are committed to ensuring that our sash window ranges (depending on chosen profile) can be coloured to any Ral or Farrow & Ball colouring.

If you see a colour that isn’t available in the Farrow & Ball or Ral colour palettes, then please do still contact us, and we will do our up most to try and achieve the window colour that you desire. The woodgrain colours in the UPVc give the appearance of a real timber window if it is tradition that you are looking for.
