Easyfix Trackglaze Horizontal – Sliding Secondary Glazing
Trackglaze Horizontal is a sliding secondary glazing system that gives you excellent heat and noise insulation, with the advantage of simple slide opening for access to your outer windows. The system comprises rigid PVC Double Sliding Track fitted around all 4 sides of the window cavity, Bristle Seal Draught Excluder for the edges of the glazing sheets and a simple rigid PVC Angle for the finger pull handle on the glazing panels.
Installation is made simple by the self-adhesive tape which is on every component, and the track lengths can be secured with other appropriate fixings if required, making sure that any screws used have countersunk heads.
The track is designed for use with 4mm thick glazing panes and where windows are over 1m in height we must recommend the use of glass as the more flexible plastic sheets can bow away from each other creating a gap at the overlap, preventing the desired thermal/noise insulation being provided.
The glass would need to be sourced locally and must be 4mm thick with the edges ground for safety. Ask your glass supplier for help or advice with this as well as the safety implications of normal and toughened glass.
Size Restriction – We recommend that glass panels are limited to 1500mm on either dimension to ensure the glass is not too heavy to install or slide.
The window cavity to be insulated must be square and true and cannot be sloping by more than 1mm in height or width. It is best to square up the cavity, if needed, before fitting Trackglaze.
Trackglaze has been designed for use without mitred corners, because the differing heights of the top and bottom track make 45° mitres unfeasible.
Trackglaze Horizontal is supplied in kits with either 1m or 2m lengths of Track and Angle Handles along with either 6m or 12m of Bristle Seal respectively.
It is supplied fully packaged, including fitting instructions, with the following self-adhesive contents in each retail pack:
- 3 lengths Top Sliding Track (deeper track)
- 1 length Bottom Sliding Track (shallow track)
- 2 lengths Angle (white adhesive tape on one outside face)
- 1 coil of Bristle Seal
Packs also contain Easyfix® Surface Preparation Wipes, which clean and degrease the window surround to give best adhesion of the self-adhesive tape.
The Kits can be purchased individually or in packs of packs of three.
Trackglaze Horizontal needs to be installed inside a window cavity. If this is not possible then you need to create one using either wood battens or the Window Conversion Angles we can supply, taking care to make the cavity to the correct size for any sheets you have ordered.
- Measure the window cavity: horizontally (measurement A) and vertically (measurement B). If either A or B is over 1m you will need to purchase the 2m Kit and if A is over 2m you will need the 3m Extension track kit.
- For the height of the glazing you require – subtract 13mm from measurement B
- Measurement A is the total glazing width of your window. For a two panel system add 4mm to measurement A and divide this between your 2 panels.
- If you are fitting over 2 panels then add a further 8mm per pane before dividing up. (e.g. a three panel will be A plus 12mm, a four A plus 20mm, etc.). This should allow an overlap on each panel to apply the Bristle Seal and ensure every panel will overlap when closed.
- For the frame you will need one length of shallow bottom track, and one length of deeper track cut to measurement A and then two lengths of deeper track at around measurement B less 30mm.
- For the Angle Handle the maximum length required would be around measurement B less 40mm.
Tools required to fit are a fine tooth saw, tape measure, pencil and a pair of scissors.
- Clean and degrease the window frame using Easyfix® Surface Preparation Wipes.
- Cut and apply magnetic strip to the plastic sheet edges on one side.
- Hold sheet to window, ensuring equal overlap on all sides.
- Trace around sheet with a pencil on the window frame.
- Apply the white metal strip just inside the pencil lines.
- For optimal adhesion, leave the panel off for 24 hours before regular use to give the adhesive best chance to bond properly before loading.
- Click the panel into place.
Window Conversion Angles: PVC Angles that can be fitted onto the face of the frame to create the required cavity for the Trackglaze systems to be fitted within.
Surface Preparation Wipes can be used to clean and degrease any surfaces before sticking the tapes in place.
Antistatic Spray can be used to diffuse the static charge on the sheet when the film have been removed to help prevent the attraction of dust and particles from the air.
Microfibre cloths can be used to clean the sheets without scratching the glazing panels.
Trackglaze Vertical: A vertical sliding system using the same tracks along with stop strips to hold panes in position.
Can the track be screwed into position?
Yes, you can screw the track down for added peace of mind but be sure to use countersunk screw heads.
Why do I have to use glass over 1m?
This is due to the flexible nature of the plastic sheets, they tend to bow under their own weight creating a gap at the overlap preventing the desired insulation.
