Solvent-based adhesive and incredibly hot asphalt disintegrate EPS. For this reason, if possibly of these is used, an acceptable include board should be installed more than the EPS. EPS can also be decomposed or melt at superior temperatures. For that reason, EPS really should not be utilized beneath a black membrane Except an appropriate deal with board is put in involving the EPS and also the membrane.

With time, thermal motion from the metal can tear as a result of fastener gaskets and enlarge holes at fasteners.
If crushed combination is specified, a stone-security mat involving the membrane and mixture need to be specified to stop puncturing the membrane.
