NEW LABORATORY TEST RESULTS FOR THE AKUSTIK + SYLOMER MOUNTS IN DOWEL-LAMINATED TIMBER (DLT) STRUCTURES

Acoustic sylomer laboratory test

Acoustic sylomer laboratory test

This article shows the tests results for floating floor installations when used with Dowel-Laminated Timber (DLT) structures, comparing them to a solution without isolation elements.

INTRODUCTION

Dowel-Laminated Timber (DLT) structures are similar to Nail-Laminated Timber (NLT) structures but without the need for nails or metal fasteners. Dowel-Laminated panels are an all-wood structure and can be easily processed using CNC machinery, allowing on site modifications.

Different tests have been carried out using different solutions for the floating floor from a naked structure to an installation with several cement board layers with our floating mounts.

THE PRODUCTS THAT HAVE BEEN TESTED ARE:

AKUSTIK + SYLOMER FLOOR MOUNTS

The Akustik + Sylomer® Floor mounts are vibration isolators that have been designed for the installation of wooden floors with a batten system. Their easy installation and low space requirement allows exceptional vibration and noise isolation as part of a floating floor application.

These mounts are typically installed every 19,69''. But this feature may be tuned in order to adapt to the load or natural frequency requirement of the application. The natural frequency at their optimal loading point reaches values below 12 Hz. These technical properties provide a high level of noise and vibration isolation when used in light wooden structures.

RESULTS OF THE LABORATORY TESTS

In order to show the acoustic advantages when using Akustik+Sylomer® Floor mounts in a Dowel-Laminated Timber structure, an independent external technological centre has performed impact noise tests using different building configurations.

Based on the obtained test results, an impact noise reduction up to 26dB can be obtained, compared to the reference configuration, without any Akustik+Sylomer® Floor mount

The tested configurations are shown below as well as different comparisons between different configuration systems:
