What is a uPVC Sliding Sash Window?
A uPVC sliding sash window is a modern, energy-efficient alternative to traditional timber sash windows, designed to replicate classic aesthetics while offering superior durability and low maintenance. Ideal for period properties, heritage homes, and modern renovations, these windows combine timeless style with modern performance.
Key Features of uPVC Sliding Sash Windows:
Smooth Sliding Mechanism – Designed with a high-performance balance system for effortless vertical sliding operation.
Traditional Aesthetic – Includes period-style details such as run-through sash horns, deep bottom rails, and sculpted frames to mimic authentic timber sash windows.
Energy Efficiency – Multi-chambered uPVC frames and double-glazing provide excellent insulation, reducing heat loss and lowering energy bills.
Low Maintenance & Weather-Resistant – Unlike traditional wooden windows, uPVC sash windows will not rot, warp, or require repainting. A simple wipe-clean surface keeps them looking pristine.
Enhanced Security – Built with reinforced frames and advanced locking systems for superior home security.
Why Choose uPVC Sliding Sash Windows?
uPVC sash windows are the perfect solution for homeowners looking to maintain a traditional aesthetic while benefiting from modern technology. With outstanding thermal efficiency, improved security, and ease of maintenance, they provide a cost-effective and long-lasting window solution.
Whether you’re renovating a period home or upgrading to more energy-efficient windows, uPVC sliding sash windows offer a stylish and practical choice.

Counterbalance Systems
Following the market uptake of uPVC sash windows, modern counterbalance systems were introduced to replace cords and weights, including spring balances and constant force coil mechanisms. These counterbalance systems enable the sashes to move smoothly and stay in position. Specific systems appear more appropriate for windows of particular sizes, which has led us to implement the following changes:
Windows with sashes up to 850mm in height will have constant force, quick release, and standard sash stops as they do now.
Windows with sashes between 851mm and 1150mm in height will have constant force, no quick release, and extended sash stops.
Windows with sashes 1151mm and over in height will have spring balances, quick release, and standard sash stops as they do now.
Please note that windows specified with PAS 24 security must have spiral balances and a fee may be applicable.
Extended Sash Stops
As listed above (point 2), on windows with sashes between 851mm and 1150mm we will be using extended sash stops, which will reduce the sash openings slightly to ensure the full rated load of the coil mechanisms isn’t surpassed.
For reference, please note the picture of the extended sash stop fitted on a 2400mm tall sash window.
Easy Clean Tilt Facility
Please note, on windows with a woodgrain finish external and smooth finish internal we are not able to offer top sash tilt facility
