Certificate type
NSAI Agrément certified, bound EPS liquid floor insulation.
Suitable for internal application to ground-supported and suspended floors in existing and new domestic and non-domestic building applications.
Typically installed:
baseTherm® is an NSAI Agrément certified, pumpable light-weight thermal and insulation screed mortar. It consists of EPS beads, fast-drying cements and Isostay proprietary additive produced and installed using a mobile floor insulation factory. It is used as a thermally insulating, non-structural, bound expanding polystyrene system (BEPS) which contributes to the thermal and acoustic performance of floors.
