Why choose vertical slider windows?
Vertical slider windows, often called sash windows, feature two panels that slide vertically within the frame. This classic window design has been used for centuries and remains a popular choice for period properties and conservation areas.
Modern PVCu vertical sliders replicate the traditional appearance of timber sash windows while offering greater durability, improved insulation, and much lower maintenance requirements.

Features & benefits
Authentic traditional styling
Vertical slider windows replicate classic timber sash windows with features such as run-through sash horns, deep bottom rails, and decorative Georgian bars.
Smooth sliding operation
Modern spring and spiral balance systems allow both sashes to slide smoothly and reliably without the traditional weights and pulleys.
Tilt-in cleaning
Both sashes tilt inward, allowing the exterior glass to be cleaned safely from inside the home.
Low maintenance
PVCu frames do not rot, warp, or require painting. A simple clean keeps them looking great for years.
Colours & finishes
Vertical slider windows are available in a wide range of colours and woodgrain finishes designed to replicate painted or stained timber.
Popular choices include White, Cream, Golden Oak, Rosewood, Anthracite Grey, and Chartwell Green.
Dual colour options are available so you can match the exterior of your property while maintaining a different interior finish.
Perfect for period and heritage homes
Vertical sliding sash windows are particularly popular in traditional and heritage properties because they replicate the appearance of original timber sash windows while meeting modern performance standards.
They are also commonly used in conservation areas where maintaining a traditional appearance is important.
