Thermally broken aluminium, vertical sliding windows, incorporating innovative polyamide thermal break technology, which creates a barrier between the cold air outside and warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U-value of the product.

VS600 incorporates the traditional styling of sash windows with the advantages of a modern thermal aluminium profile. A traditional sash window may be used in heritage and conservation areas where Georgian and Victorian architecture is predominant. The ease of operation and excellent natural ventilation rates means that VS600 is also suited to high occupancy buildings.

The window offers a flush opening with no projection into or out of the building, it is a style of window which is frequently used in schools and hospitals. The hardware utilizes various standard hardware designs. As well as the vertical sliding sash, VS600 features a ‘tilt in’ operation that facilitates the cleaning of the external glass.
