Impact sound insulation system that provides the direct glueing of the ceramic on the mats of the dBred range
It is realisable in reduced thicknesses from cement surface or pre-existent floors. It is particulary suited to reconstruction interventions and in the reduction of the structural transmission of impact noises on stairs. The whole cycle of application needs a cement adhesive suitable to the floor.
SURFACES SUITABLE FOR APPLICATION
Edilteco® single-layer lightweight base screeds:
■ Politerm® Blu (from 300 kg/m3), Isolcap Fein 300, Isolcap XX 500, Isolcap Speed 525, Isolcap Max 650, Isolcap Max 800.
■ Traditional or self-levelling cement screeds.
■ Self-levelling screed with anhydrite base.
■ Existent ceramic floors.
■ Tensile resistance: > 0,4 N/mm2
(UNI EN 12004-2).
■ Impact sound reduction: values of ∆Lw
up to 17 dB (UNI EN ISO 140-7).
■ Load at 25% compression: 0,28 N/mm2
(EN ISO 3386-2).
DBRED PIANO ZERO STEPS
The intervention is optimal for the insulation of structural elements made of reinforced concrete such as stairs and landing or common passages even if already existent.
■ Application of the polyethylene perimeter adhesive strip dBred LF5 only vertically.
■ Glue application with cogged trowel of 6 - 8 mm according with application layer’s planarity.
■ Laying of dBred mat.
■ Passage with overload roll of 25 kg with the aim to allow a perfect adhesion between glue and the mat.
■ Sealing of the dBred mat junctions with silicone.
■ Wait for the grip of the glue.
■ Apply the glue on the mat with a 10 mm toothed spatula (curved toothing) in order to obtain the total adhesion of the flooring covering.
■ Application of the ceramic coating with spacings of variable width according to the coating’s format. It is recommended to realize spacings of at least 3 mm for coatings with dimensions up to 60 cm and surfaces of no more than 20 m2; and spacings of 5 mm for coatings with the greater side of 60 cm and/or surfaces over 20 m2.
■ Fill in the joints (traditional method).
■ Apply the baseboard.
