SylCer – Acoustic Underlay for Ceramic Floors

SylCer is a 3 mm high-density soundproofing underlay designed for use beneath ceramic and stone floor finishes. It is the perfect choice for improving sound insulation in renovation and restoration projects, particularly when a thin solution is required without removing existing flooring.

Composed of SBR and EPDM rubber granules bound with polyurethane, SylCer effectively reduces impact noise such as footsteps, knocks, and vibration transfer. Its certified performance ensures compliance with modern building regulations and acoustic comfort standards.

How It Works

SylCer acts as an impact noise insulation layer placed directly beneath new ceramic or stone finishes. The dense structure of recycled rubber granules absorbs sound energy and vibration before they can pass through the floor slab.

Its slightly porous surface texture increases glue adhesion, while its dimensional stability ensures a smooth, uniform installation even on irregular substrates.

Key Benefits

• Proven impact sound reduction of 17 dB.
• Designed for renovation projects requiring minimal floor height increase.
• Improves glue adhesion thanks to surface porosity.
• Fast, precise installation with minimal waste.
• Dimensional stability for accurate, long-lasting performance.

Installation Overview

• Fix an edging strip around the perimeter of the room.
• Apply a thin layer of adhesive to the concrete and place the SylCer underlay.
• Smooth the membrane using a roller to remove air bubbles.
• Apply a concrete adhesive over the SylCer and lay ceramic or stone tiles on top.
• Finish with grout and trim any excess edging.

Installation is simple and does not require specialised tools. Acoustic performance can be verified on-site by a certified technician if needed.
