About Filler Blocks
Profiled foam filler blocks are available for profiled sheets to provide a seal between the profiled sheets and the flashings.
Correct filler block
E.P.D.M. is the most common material used in foam fillers and reference should be made to the manufacturers’ recommendations in repect of resilience to temperature changes, fire resistance etc.
It is important to order the correct filler block, i.e., large rib or small rib to match either the outer or the inner skin of the profile.
