Colour Ranges & Glazing Designs for Sliding Sash Windows

We appreciate that every home is different and unique in its own way so personalised design is a very important stage of the process.
We can design your windows or doors to ensure they match the style of your home by providing a wide range of colour options and glazing designs for you to choose from.


For our PVC Conservation Range, we can use traditional white or cream coloured paint to give it a quality painted wood finish and we can also apply a variety of wood effect finishes if you want your windows looking like authentic timber frames.


The latest spray on paint we use has been designed specifically to bond with PVC so as to provide an extra protective coating and to make certain that they never need to be painted again in the future. It is also chip-roof, crack-proof and flake-proof so you can rest assured that regular maintenance is not something you need to worry about. Our team of expert designers will be able to answer any questions you have along the way.


We look forward to hearing from you.
