Aluminium sliding windows

Our sliding aluminium windows are versatile, durable solution for flats, commercial properties and domestic houses. Unlike uPVC and timber sliders, aluminium sliders can slide both vertically and horizontally.

The dual slide is the new solution to vertical and horizontal sliding windows, utilising advanced polyamide thermal break technology. The dual slide provides high thermal performance without the need to resort to foam filled profiles or complex and costly sealed unit specifications.

Giving you more glass options

The current building regulation for replacement windows requires a minimum of a C energy rating. Osborn Glass as standard offer the higher A energy rated window as standard. There is now an option to enhance the energy-saving with triple glazed windows.

Our windows are glazed with standard clear or obscure Pilkington glass, depending on your requirements. Many different types of decoration can be applied. By applying lead, Georgian bar or even a stained glass design to the window, you can add that personal touch.
