ISOLCAP XX 500

PRE-MIXED, FIBRE-REINFORCED, LIGHTWEIGHT AND THERMALLY INSULATING SUBFLOOR. 500 kg/m3 (31.2 lb/ft³)

ISOLCAP XX 500 is the fibre-reinforced lightweight pre-mixed subfloor for projects that need more strength without giving up insulation. At 500 kg/m³ (31.2 lb/ft³) and with polypropylene fibres it achieves a compressive strength of 2.24 N/mm² (325 psi) and forms a compact, cohesive layer, ideal as a single-layer screed under glued floors and where loads are higher.

Made with EPS beads coated with E.I.A. additive, selected aggregates and fibres, it keeps a thermal conductivity of λD 0.104 W/mK (0.72 BTU·in/(h·ft²·°F)). It does not settle, does not shrink and does not crack.

At 5 cm (2 in) thickness ceramic tiles can be laid after about 5 days and floating parquet after about 10 days; after 28 days the residual moisture is below 2%, which makes it suitable for wood-frame buildings too.

It is mixed with a drill and whisk, a cement mixer or a mixer, and pumped to the floor with POLITERM® MACHINE, ISOLCAP MACHINE, a properly fitted plastering machine or a truck mixer and concrete pump. With DBRED FONOTECH 5 it contributes to impact sound reduction (ΔLw 17 dB). Reaction to fire A2-s1,d0.

PACKAGING

Single-layer lightweight screeds for floor coverings laid with adhesive (ceramic, porcelain stoneware, clinker, terracotta, parquet). For glued parquet, a KRONOS AUTOLIV skim coat (min. 5 mm (0.197 in)) is mandatory.
Lightweight thermally insulating subfloors, with or without slopes.
Lightweight infill and levelling layers.
Roof insulation (pitched or flat), suitable for direct laying of waterproofing membranes or solvent-free liquid membranes.
Not suitable for direct laying of resilient floor coverings.
