Smart’s VS600 aluminium sash windows are designed to replicate the appearance of traditional timber sliding sash windows while delivering superior functionality and longevity. The vertical sliding mechanism allows both the top and bottom sashes to move, providing excellent ventilation options. These windows are particularly suited to older properties and conservation areas where Victorian architecture is prevalent, but they also work beautifully in modern homes seeking a touch of traditional elegance.
For homeowners looking for a low maintenance alternative to timber, these aluminium sash windows offer the perfect solution. With their excellent corrosion resistance and structural strength, they will stand the test of time without warping, rotting, or requiring repainting.
Book a free appointmentOur aluminium sliding sash windows come with a range of features designed to improve both performance and aesthetics:
These windows perfectly replicate the look of classic sash windows, including the option of decorative sash horns and traditional proportions that maintain your property's character.
Our aluminium sliding sash windows include a clever tilt mechanism that allows the sashes to tilt inward, making cleaning the exterior glass simple and safe, useful for high and hard to reach windows.
With a U-value of 1.6W/m²K and modern double glazing, these windows help keep your home warm and could reduce your energy bills.
Despite their strength, our aluminium frames feature slim sightlines, maximising the glass area and allowing more natural light into your home.
Aluminium offers numerous advantages over other materials for vertical sliding sash windows.

Aluminium offers several advantages over other materials. Compared to uPVC, aluminium frames can be slimmer while maintaining strength, allowing for larger glass areas. Compared to timber, aluminium requires virtually no maintenance, won't rot or warp, and offers superior durability.
