NSAI Agrément Certificate No. 20/0415

This Certificate relates to the Altherm Insulating Concrete Formwork (ICF) System, which consists of modular interlocking expanded polystyrene (EPS) building blocks (graphite enhanced) for permanent formwork for the construction of in-situ concrete walls. 


Each block (form) is based on two EPS panels separated by 150 or 200mm with embedded polypropylene connectors bridging the gap. The overall block thickness ranges from 300 to 400mm, depending on the required EPS and concrete core thickness.

BBA Agrément Certificate

This Agrément Certificate Product Sheet relates to lglu Global Block, insulated concrete formwork   comprising two leaves of expanded polystyrene elements with internal web spacers. 


The system provides permanent insulated formwork for use, with height restrictions,  in the formation of loadbearing and non-loadbearing internal, external and separating walls in domestic and non-domestic buildings.
