EIFS & ETICS

According to the definitions of the lnternational Building Code andASTM International, an Exterior Insulation and Finish System (EIFSis a nonload bearing, exterior wall cladding system that consists ofan insulation board attached either adhesively or mechanically, orboth, to the substrate; an integrally reinforced base coat; and atextured protective finish coat. In Europe, systems similar to EIFSare known as External Wall lnsulation System (EWIS) and ExternaThermal Insulation Cladding System (ETICS)

The popularity of ElFS comes from its insulating qualities to reduce thermal loads on the exterior building wall and the light weight, lowcost, and the ability of the system to be sculpted into shapes andpatterns to achieve different aesthetic effects.

The mortar required by the ElFS/ETICS should have excellent adhesion and flexibility under various outdoor climate conditions. Newsanda cellulose ether are widely used for adhesive mortars and the embedding mortars in EIFS/ETICS.

Newsanda redispersible powder provide increased adhesion to all substrates, especially on EPS,XPS and MW boards, along with flexibility and impact resistance, and offer surface abrasion resistance and durability. The use of Newsanda products is essential for the workability, water retention, open timeand general physical properties of the ElFS/ETICS mortars. Newsanda redispersible powder and cellulose ether products can be used together to impart premium performance ofthe mortars.
