Description

NU-THERM is a cavity-based Exterior Insulation and Finishing System (EIFS) wall cladding. It is an external wall cladding system for 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 thickness of fibreglass mesh reinforced polymer-modified cement-based plaster. The plaster finish can be textured to give either a sponge or adobe appearance. The plaster system is finished with an acrylic exterior coating system.

The system incorporates a primary and secondary means of weather resistance (first and second line of defence) against water penetration by separating the cladding from the external wall framing with a nominal 20 mm drained cavity.
