EIFS (Exterior Insulation Finish Systems)


PlastiSpan® Insulation is used in Cathedral Ceiling, Continuous Insulation, Exterior Foundation, Interior Basement Walls, Basement Floor, Under Slab, Hydronic, EIFS and handi-pac Packaging & Display.



PlastiSpan EFS is a specifically manufactured expanded polystyrene
insulation board to meet the requirements of various types of exterior
protective coatings as classified by the Exterior Insulation Manufactures
Association.

The EPS insulation boards manufactured by Plasti-Fab Ltd. are quality
controlled by a third party Quality Assurance Program monitored/certified
by Intertek (ITS) to meet the CAN/ULC-S701 standard.

EIFS are non-load bearing exterior wall cladding systems typically
consisting of PlastiSpan EFS insulation attached to a substrate, an integrally
reinforced base coat applied to the face of the PlastiSpan EFS insulation
and a protective finish applied to the surface of the base coat. The
PlastiSpan EFS insulation is attached to the substrate using specially
formulated adhesives and/or mechanical attachment.

PlastiSpan EFS insulation used in EIFS applications covers the outside of
the building so that the structure is isolated from the wide temperature
fluctuations of the climate. This reduces expansion and contraction of the
structure and stabilizes interior temperatures.
