​Frequently Asked Questions about EIFS

What is EIFS?

Exterior Insulation and Finish Systems (EIFS) are non-load bearing, exterior wall cladding systems that consist of insulation board that is either adhesively or mechanically attached to the substrate; an integrally reinforced base coat; and a protective textured finish coat.


Are your EIFS NFPA 285 compliant?

Yes, our EIFS meet NFPA 285 for use in types I through IV construction. This information can be found in the system evaluation reports or on our NFPA 285 Wall Assembly brochure.

What is the R-Value of your EIFS?

The R-value of an EIFS is determined by the thickness of the continuous insulation layer. The below chart outlines R-values of the most common insulation used in EIFS; 1 lb. density expanded polystyrene (EPS).

Can your finishes be tinted?

Yes! All of our finishes can be tinted to the color of your choice. We have a large selection of standard colors in our Color Selector Guide and are able to tint our finish to custom colors. Our skilled color matching team can closely match virtually any color of your choice. Please contact your local Senergy distributor to place a standard or a custom order.

Can your EIFS be adhesively attached to the Huber Zip System?

Huber does not allow for the adhesive attachment of EIFS to their Zip System. Therefore, you only use one of our mechanically fastened systems.
