Vertical sliding sash windows remain one of the most sought-after styles across Derbyshire, especially on period and heritage homes. Our uPVC vertical sliders replicate the charm of traditional timber box sash windows with modern thermal performance, enhanced security and the low-maintenance benefits of contemporary materials.
Heritage Authenticity
Designed to replicate traditional timber sash windows, with authentic details such as run-through sash horns, deep bottom rails and a slim midrail option for period properties and conservation areas.
Slide & Tilt Facility
Both sashes slide vertically for ventilation, with an easy-clean tilt function so you can wash the outside of your windows from indoors — no ladders required.
Secure by Design
Spring balance system with high-security sash locks and keeps, with PAS 24 upgrade packages available for enhanced security on new-build installations.
Energy Efficient
A-rated energy performance as standard, with advanced double glazing and thermal options to help keep your home warmer and reduce energy bills.
