The unit we used is called a Portavent Vitris (this is available through NFK Glazing supplies - http://www.nfk.com.au/Default.aspx?A=ProductSearch&ID=/searchProducts.html. Whilst it is not truly a cavity slider but the builder made it this way - attached is another image of it sliding along the wall - works with toughened or heat strengthened laminate - the other version would be a Tornex cavity slider (http://www.tornex.com.au/) this is a true cavity unit that also allows you to use glass - both can be a DIY installation (by the experienced) but you will need to get someone to assist you with the glass installation (definitely required to be carried out by an experience glazier) - Hope this helps, let me know if you need anything else
