The system features low line glazing gaskets that will accept 28mm sealed units, achieves a U-value of 1.6 and also features a concealed drainage and concealed coupling option.

As well as the vertical sliding sash, VS600 also features a ‘tilt in’ operation that facilitates the cleaning of the external glass.
