EASYFIX TRACKGLAZE SECONDARY GLAZING

Trackglaze is a welcome addition to the secondary glazing products made and supplied by Tubeway (Sales) Ltd under the Easyfix DIY banner, which are designed to reduce heat loss, insulate against noise intrusion and look smart. Trackglaze uses PVC Double Sliding Tracks on all sides of the window cavity, Bristle seal on all edges of the glazing sheets and a simple PVC Angle as a finger pull to open and close as required. Each component has self adhesive tape applied for easy installation with a minimum of tools, although the track lengths can be strengthened with other appropriate fixings if you require.

In common with our other DIY glazing systems, Trackglaze is suitable for use where traditional double glazing is not feasible, such as in listed buildings, or where the costs or time available do not justify it. Once you have installed Trackglaze, access to your outer windows is simply a slide away for ventilation or cleaning, and it does not need to be removed in summer, just left open, although the glazing sheets can be removed safely in seconds if required. Another useful feature of Trackglaze is that it can be used with more than 2 glazing sheets, depending on the width of the window or your preference, for example, to line up the internal glazing sheets with the outer windows for neatness, or to coincide with the parts of the outer frame that open.

If you are using glass with Trackglaze, it is recommended that both height and width are limited to 1500mm in order to make them light enough to install and slide safely. Plastic glazing sheets are lighter, but larger sheets have a tendency to bow vertically under their own weight, so it is recommended that the height of acrylic or polycarbonate sheets within Trackglaze is limited to 1000mm (1m). The angle handles included in the kits further reduce the risk of bowing. The ideal shape for glazing panels using this system is wider than taller, to give extra stability when sliding - if in doubt, please ask your glazier or sheet supplier for more advice, and remember that all glazing sheets, but particularly glass, must have sharp edges removed before handling, for safety reasons.

Trackglaze is designed for use with 4mm glass, or 4mm Acrylic or Polycarbonate glazing sheets. As shown in the adjacent drawings, after the sliding track is fitted to the window cavity;

• firstly the prepared glazing is pushed up into the deep top track
• secondly lifted over the lip of the bottom track
• finally positioned into the corresponding bottom track
