Sylwood Acoustic Underlay for Engineered Floors
Sylwood Acoustic Underlay for Engineered Floors
Sylwood acoustic underlay is an innovative, 3mm thick, high performance product ideal for acoustically upgrading existing buildings during renovation or new installation of wooden floors.
Sylwood is a high density, low thickness recycled rubber mat made of SBR and cork granules, that dampens and absorbs noise transmission from footfall and other types of impact noise.
It is laid directly onto existing concrete screeds ready to receive the new wooden or laminate floor.
Part of the Isolgomma range of above screed acoustic underlays, Sylwood acoustic underlay has an impact sound insulation improvement value of 20dB when it and the wooden floor are loose laid and an improvement value of 17dB when it and the wooden floor are glued using a suitable adhesive.
Features
- Minimal thickness – 3mm
- For use under all types of wooden floor and laminates
- Easy installation
- Eco-friendly – manufactured from recycled materials
Installation
Sylwood impact sound insulation can be either glued or loose laid on top of the screed. It is disconnected from the perimeter walls with a self adhesive flanking strip. The wooden floor or laminate is then laid directly on the sound insulation mat.
