There are two types of fixings specific to existing floors and new floors. They are made from non-corrosive nylon and are used to fix the EXPOL panels in place.
- Existing Floors: EXPOL Z Clips are designed as a push fit between the panel and the joist.
- New Floors: EXPOL Joist Saddles for R2.5 & R3.1 (extended length) are designed to slip over the joist to support and secure the 100mm panel.
