Abstract [en]

The effect of using elastic glue in between a timber construction's two floor layers - gypsum board and particle board - was investigated. In a new timber based building, the impact sound insulation was reduced by 2 dB when elastic glue was introduced in the production. To find out the long-term effects, six different elastic glues was involved in a laboratory test in which layers of floor plaster board and particle board, 0.5x0.6m2, were glued together. The test has so far been running for two years. A majority of the glues showed significant reduction in modal damping ratio after a couple of months while a couple of them, to high extent, have maintained their properties over time.
