boarding the ceiling leave 12.5mm continuous<br />
gap along the line of the movement joint.<br />

Synia - <strong>The</strong> new plasterboard innovation from Lafarge.<br />
Synia is a unique plasterboard design from Lafarge that<br />
provides the ultimate flat ceiling in drylining.<br />
Traditionally, drylining plasterboards are manufactured<br />
with 2 tapered edges in order to create a seamless finish<br />
when jointed. For ceilings this has presented installers<br />
with the problem of extra planing, labour costs and time<br />
for the cut ends.<br />
Synia has been created with a unique edge design<br />
which, once fixed, reveals a 4 tapered edge for jointing.<br />
This offers the installer a faster, easier solution, resulting<br />
in the ultimate flat ceiling.<br />
