Energy
requirements are pressing designers to find ways to incorporate
insulation behind all claddings. This can be a challenge, but the
plastering industry has done it for years and offers a variety of
systems or assemblies.
Exterior
insulated finish systems were specifically invented to emulate stucco
and add the benefit of continuous insulation. EIFS should be the first
choice for most commercial projects and all projects that use masonry as
the substrate. EIFS on framed walls are required to have a drainage
system and most meet current rainscreen requirements. Caveats include:
Avoid putting foam plastic on ceilings and adhere to that manufacturer’s
system requirements.
