Description

NU-THERM EIFS Wall Cladding System is a cavity-based exterior insulation and finishing system (EIFS) wall cladding. It is for use on residential and light commercial type buildings where domestic construction techniques are used.

The system consists of expanded polystyrene (EPS) sheets fixed over polystyrene battens to form the cavity. The coating system consists of 8 mm thick fibreglass mesh reinforced, polymer-modified cement-based plaster, which is finished with a latex exterior paint system. The plaster finish can be textured to give either a sponge or adobe appearance.
