Easyfix Trackglaze - Sliding Secondary Glazing

print

Trackglaze is a horizontal sliding secondary glazing system using 4mm thick glazing sheet that offers full thermal insulation when closed, along with immediate access to the outer windows when required. It comprises PVC double sliding tracks on all 4 sides of the window cavity, a simple bristle seal around each glazing sheet and a finger pull angle to use as a handle. Each of these components has self adhesive tape applied.

Once the tracks have been cut and stuck into place, and the bristle seal applied to the glazing sheet faces, the sheets are inserted into the tracks using the Up-Over-Down technique shown on the diagrams below, which leaves the bristle seal within the tracks around the frame for maximum insulation. Sheets can be easily removed by reversing the method.

Trackglaze has several unique features as a DIY sliding system. Two or more panels can be used within one frame, enabling the joints between the panels to be lined up with frames of the outer windows. Ventilation and cleaning within the cavity could not be simpler to achieve, by simply sliding one or more panels, which are just as easily closed. The system can be used with either 4mm glass, or 4mm plastic sheet, with the following considerations:

  • Glass is comparitively heavy, so we recommend panes of 2 square metres or less (approx 20kg) in order to keep them manageable when installing and operating. A low wide pane will slide more easily than a tall narrow one, because the centre of gravity is lower. Always grind the edges of glass to make them safe to handle
  • Plastic Sheet is around half the weight of glass, but tall panels will bow under their own weight (breaking the thermal seal), particularly if left in the open position i.e. supported only at the top and bottom. The Angle handle will reduce bowing, but we recommend a maximum height of 1m.

trackglaze sliding secondary glazingTrackglaze is supplied in kits with either 1m or 2m lengths of Track and Angle. Each kit contains 1 length of shallow bottom track, 3 of deeper top track (for cavity sides as well) and 2 lengths of Angle. 6m or 12m of Bristle Seal, and 3 or 6 Surface Preparation Wipes (for 1m and 2m kits respectively) are included with instructions. Although the lengths in the kits can be butted up together to make wider spans than 2m, we now offer 3m Extension Pairs, which are one 3m length each of the top and bottom tracks, to be used in addition to the 1m and 2m kits. This enables longer unbroken tracks to be used and is particularly useful for office installations.
