IEFS INSTALLATION

External Insulation and Finishing System (EIFS)

EIFS System Components

ADHESIVE - Cement containing or cement free adhesive based on aqueous or powder dispersions to bond the thermal insulating (EPS) board to the substrate.
 
BASE COAT - Cement containing or cement free coating based on aqueous or powder dispersions for the embeddement of a mesh and serving as an intermediate, crack-bridging layer between the thermal insulating board and the textured coating top coat.
 
TOP COAT / TEXTURED COATING - Synthetic stuccos or finishes based on aqueous polymer dispersions and containing no cement, but having the appearance of mineral plasters or stuccos.  To be used as EIFS top coat or as coating itself for direct application to the substrate.
 
Most common systems:
The cementitious base coat is used as adhesive.
 

Type of adhesives:

2-part (2K)           :   Slurry + Cement to be added at site
Single part (1K)    :   Water to be added at site
 

EIFS Insulation Board

   > Expanded Poly-styrene (EPS) board
   > Poly-urethane (PU) board
   > Rockwool board
   > Mineral fiber board
 

Important Factors:

   > Density of the board
   > Thickness of the board
   > Thermal coefficient
   > Fire retardancy
