Exterior Insulation and Finish System
Use this CSI 3 part SimpleSpecs™ master specification to specify an Exterior Insulation and Finish System. This system is often called EIFS.
This exterior cladding system incorporates a weather barrier, rigid insulation, and an exterior finish, with all components typically furnished by the same manufacturer.
Exterior Insulation Finishing Systems are available in multiple types:
Class PB uses expanded polystyrene insulation adhered to the substrate, standard glass fiber mesh reinforcing, and standard coatings.
Class PM uses either expanded or extruded polystyrene insulation, heavier mesh, and heavier coatings.
Exterior Insulation Impact Resistance
Impact resistance of EIFS is largely dependent on the type of reinforcing used. Standard is suitable where no contact with the system is anticipated, while Medium, High, and Ultra-High use heavier reinforcing and can withstand varying amounts of impact.
Some manufacturers offer hybrid systems with enhanced impact resistance that can incorporate wire mesh or metal lath and a plaster base coat.

The SimpleSpecs™ master specs concept
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable. In fact, quite the opposite is true. Having shorter, easily understood specifications makes us less likely to have problems in the field.
A belief that having lots of words protects us from a Contactor making mistakes. There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit
SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.
Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.
Hidden Guide Text
Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.
SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually. Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
