Description
VIBRO LAYMENT impact resistant acoustic underlays are high quality products suitable for every floor covering. They provide high impact sound insulation values, are very durable and low in emissions. Acoustic Underlay is a permanently elastic material and can be supplied in rolls, sheets or molded parts. Acoustic Underlay is suitable for all applications which require attenuation of impact sound and vibration, durability and resistance to mechanical loads.
It is used when superior sound control is required in multi-family housing, high-rises, or commercial buildings and protects ceramic tile, porcelain, and stone from substrate cracks. Engineered for direct adhered floor coverings such as tile, stone, wood, and vinyl floor coverings. It has been environmentally designed for sound isolation and impact noise control under floating laminate flooring, under screed, under tiles, engineered wood and solid wood flooring. It is an excellent choice for commercial and residential installations. The product system has been engineered for all sub floors.

Frequently Asked Questions
1. What thickness of acoustic underlay is best for tile floors in Riyadh apartments?
For ceramic or porcelain tile floors, a rubber or rubber cork composite underlay between 3mm and 5mm is generally optimal. Thicker underlays under rigid tiles can cause bonding issues, so always confirm the maximum underlay thickness with your tile adhesive supplier.
2. Is acoustic underlay required by Saudi building codes?
Saudi building codes increasingly incorporate acoustic performance requirements, particularly for residential towers and hospitality developments. While specific underlay mandates vary by project type and municipality, specifying acoustic underlay is standard practice for any multi storey building where occupant comfort matters.
3. Can I use the same acoustic underlay under both LVT and tiles?
No. Underlays are flooring specific. LVT requires a thin, dense underlay that provides stable support without causing the planks to flex. Tiles require a different decoupling system. Using the wrong underlay under a tile floor can lead to cracked grout and adhesive failure.
4. How long does a rubber acoustic underlay last in Saudi conditions?
High quality recycled rubber underlays typically deliver consistent acoustic performance for 20 years or more. The key is proper installation ensuring the subfloor is clean, flat, and dry. Saudi climatic conditions do not significantly affect subfloor installed rubber underlays when installation follows the manufacturer's guidelines.
5. What is the difference between soundproofing and acoustic underlay?
Soundproofing refers to blocking sound transmission between spaces entirely typically achieved through mass, decoupling, and sealing. Acoustic underlay is one component within a broader acoustic assembly that reduces impact and airborne noise transfer through the floor. It contributes to soundproofing but does not replace the need for a complete acoustic design in high specification projects.
