SlimSASH Windows

The SlimSASH is the more elegant option from our sash window range, due to their reduced sightlines. This allows for more daylight to enter a room via the large glass area. They are constructed with a chamfered external profile, and a choice of Chamfered or Sculptured internal glazing.

Utilising a unique 6-chamber, SlimSASH frame, the 70mm uPVC windows offer high thermal efficiency and a strong structure. Despite their elegant profile, these windows offer efficient insulation and meet high security standards. These SlimSASH windows are an ideal choice, coming in a wide array of colours and finishes, so we can tailor the style to suit your home perfectly.

Design Features

  • Internally beaded for enhanced security
  • Slimline profile of the frame allows for a larger glass area and more daylight
  • Weather-resistant uPVC, offering easy maintenance
  • Full profile welded
  • Various handle options, including push-button and key lockable (see additional features)

Frame Options

Chamfered Frame

The Chamfered frame has a flatter, neater appearance, meaning more of the glass is visible and the uPVC frame is less imposing. This means more daylight can enter your home. This style of window is ideally suited to a wide range of properties, especially for when you want to take advantage of the extra light.

Sculptured Frame

Our Sculptured frame has a more curvaceous and decorative finish when compared with the Chamfered profile. This style is the ideal application for conservatories or generally larger windows, where the extra amount of light is not an issue or deal-breaker. The traditional frame size can come in a wide array of colours and finishes.
