ISOLCAP FEIN 300

PRE-MIXED, LIGHTWEIGHT AND THERMALLY INSULATING SUBFLOOR. 18.7 lb/ft³ (300 kg/m3)

ISOLCAP FEIN 300 is the pre-mixed lightweight insulating subfloor that also works as a screed: at 18.7 lb/ft³ (300 kg/m³) it creates a single-layer screed on which ceramic tiles, stoneware, terracotta or parquet can be glued directly, avoiding a separate subfloor plus screed. You save time, thickness and weight.

Made with EPS beads coated with E.I.A. additive, it combines thermal insulation (λD 0.54 BTU·in/(h·ft²·°F) (0.078 W/(m·K))) with good strength (234 psi (1.61 N/mm²) in compression). It does not settle, does not shrink and does not crack, and it is also suitable as a base for roof waterproofing.

With very little mixing water it dries quickly: at 2 in (5 cm) thickness ceramic tiles can be laid after about 96 hours and floating parquet after about 7 days. After 28 days the residual moisture is below 2%, a decisive advantage in wood-frame buildings.

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. Combined with DBRED FONOTECH 5 it contributes to impact sound insulation (ΔLw 26 dB with 2 3/4 in (7 cm)). 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. 0.197 in (5 mm)) is mandatory.
Lightweight thermally insulating subfloors, with or without slopes.
Lightweight infill and leveling 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.
