Sliding & Fixed

A versatile sliding and fixed window system suitable for residential and low rise commercial applications. With a standard frame width of 47.5 mm, and alternative 101.5 mm frame, this system represents one of the flagship products of the G.James range.



  • XO, XOX and OXXO configurations.
  • Continuous jamb window walls.
  • Standard, arched, raked and circular shaped fixed windows
  • Face fix window, suitable for transportable building applications.
  • Flush face window, suitable for light commercial sheds and Class 10 buildings.


  • Product tested at the NATA Accredited G.James Testing Laboratory
  • Range of 150, 300 and 450 Pascal water rated products
  • Accommodates up to 6.76 mm glass
  • Sashes are independent of the perimeter frame to minimise the transfer of building loads onto the glass.
  • Height adjustable rollers incorporate a large 16 mm diameter nylon tyre (smaller diameter wheels tend to skid, flat spot and eventually scour the paint from the track).
  • A rigid thermoplastic inlay fitted to the sill profile closes off the sill cavity from small debris etc. and provides a baffle for drainage.
  • A pivot action, self-latching handle located at the mullion (not the jamb) for easy access.
  • Acoustic upgrades to a maximum STC 30 available.
  • Crimsafe, barrier and fly screens can be accommodated within the perimeter frame. Fly screens can be installed or removed either externally or internally.
  • Accessories include: 135° & 90° couplers; colonial & federation (decorative) bars; secondary locking via vent lock (located at the sill); and cavity closer section (not applicable to the 101 mm frame).
  • Combination units can incorporate awning/casement, louvre & double hung window products.

101.6 mm Frame Specific Features

  • Product tested at the NATA Accredited G.James Testing Laboratory
  • Offers better value and more aesthetic appeal when compared with the 165 Series.
  • All interlock combinations (excluding 130-043) remain within the frame line (internal and external).
  • Ideal for matching or coupling to other 101 mm framed commercial products as there is no step-back in the glazing line (as is the case with the 130-035 (47.5 – 101.5 mm) adaptor).
