Why Choose Vertical Slider Windows by Rehau?
Rehau Vertical Sliders replicate the classic appearance of timber sash windows but offer all the benefits of modern uPVC. These windows are specifically designed to blend seamlessly into period properties, combining heritage aesthetics with:

With Rehau’s authentic design, your new vertical sliders will look the part while outperforming traditional timber in durability and insulation.
Replacing Sash Windows in Kent: What Are Your Options?
If you live in a Georgian, Victorian, or Edwardian property, chances are your home features original timber sash windows. While beautiful, these can suffer from:
Draughts and heat loss
Rotting or swelling timber
Difficult opening mechanisms
High maintenance costs
J Paterson specialises in replacing these outdated windows with Rehau uPVC vertical sliders, giving you the best of both worlds—historic charm and modern performance.
We offer:
Custom colour options, including woodgrain finishes that mimic original timber
Slim sightlines for authentic proportions
Bespoke sizing to match existing window apertures
Decorative sash horns and Georgian bars for period detailing
Can You Install Vertical Sliders Windows in a Conservation Area?
Yes—but with caution and care.
Conservation areas in Kent protect the character and heritage of historic neighbourhoods. As a result, planning permission may be required for window replacements, especially if you’re changing materials (e.g. timber to uPVC).
However, thanks to Rehau’s faithful reproduction of traditional sash windows, our vertical sliders often meet local authority criteria for like-for-like replacements.
At J Paterson, we offer expert guidance on planning regulations. Provide detailed CAD drawings and product specifications for planning applications. Liaise with local conservation officers to ensure compliance. Use Rehau-approved heritage profiles designed for sensitive areas
