Product Overview
This is an aluminium take on the traditional vertical sliding sash window. It’s designed for heritage properties and conservation areas, but also works in modern buildings where you want a period aesthetic or need a flush opening
The flush design means the window doesn’t stick out when open. The tilt-in operation makes cleaning straightforward, even on upper storeys. If you’re renovating a Victorian terrace or working on a building where planning requires traditional fenestration, this gives you the aesthetic with better durability and thermal performance than timber.

Design and Configuration Options
The VS600 is available in a range of RAL colours and finishes to suit period properties or contemporary builds.
Window dimensions can be configured within the maximum limits (1600mm wide at 1300mm high, or 2800mm high at 750mm wide), and panels can be arranged in various combinations to suit your opening.
The concealed hardware and low-line glazing gaskets maintain a traditional appearance, which is particularly important in conservation areas where planning requirements are strict.
