Thermal and Sound Insulation Properties of Organic Biocomposite Mixtures. [PDF]

Polymers (Basel)
Sustainable building materials with excellent thermal stability and sound insulation are crucial for eco-friendly construction. This study investigates biocomposites made from cellulose pulp reinforced with beeswax, fir resin, and natural fillers like horsetail, rice flour, and fir needles. Eight formulations were obtained, and their thermal resistance,

Sound insulation properties of sandwich panels

IOP Conference Series: Materials Science and Engineering, 2020
Abstract The sound transmission via building enclosures of finite dimensions has a resonant and inertial components. The resonant transmission of sound takes place in the mode of self-induced vibrations depending on the degree of self-coordination of its own wave field with sound fields present in the air on both sides of the enclosure ...
