How to install Base Tracks for EWI / ETICS Systems
Base Tracks - AKA Base Profiles or Starter Tracks - Base Tracks are aluminium moulded profiles that are mechanically fixed to the substrate. The tracks are used to perform a starting point just above damp proof cause to hold the EPS boards and fix drip beads to ensure water flows away in the correct manner. The track should be of similar width to that of the EPS board and fixed with suitable fixings to the substrate.
The type of fixing used to secure the base track differs depending on the substrate usually at 300 mm maximum centres. Connectors are used to attach lengths together. For uneven substrates use spacers to bridge the gaps to provide a solid fixing. Beads and expansion joints are incorporated as specified. For solid walls use a hammer screw fixing, usually, 6 x 35mm is sufficient.
