Acoustic and thermal performances assessment of sustainable insulation panels made from cardboard waste and natural fibers

Pluoštinių kanapių spalių garso sugerties ir garso perdavimo sumažėjimo tyrimai

“…Zulkifli et al (2010) nustatė, kad kokoso pluoštas gali būti naudojamas kaip kompozitinė medžiaga su medvilniniu pagrindu ir perforuota plokštele, tada garso sugertis gali padidėti iki 0,94-0,95 dažnių diapazone nuo 2600 iki 2700 Hz (Zulkifli et al, 2010). Ouakarrouch et al (2022) gamino ir tyrinėjo ekologiškas kompozitines plokštes, pagamintas iš 60 % kartono atliekų ir 40 % natūralaus pluošto. Augalinis pluoštas buvo gaunamas iš nendrių, figos medžio, palmės riešutmedžio, alyvmedžio, cukranendrių stiebų, kviečių šiaudų ir ašuotenės daugiamečių žolių.…”

Exploring the potential of recycled textile panels to improve sound insulation in buildings

“…Furthermore, this could limit the environmental impacts associated with the consumption of virgin resources by construction sector [9]. The most part of existing studies on acoustic performances of green building materials concerns the material scale investigations, focusing on their absorption properties [10][11][12]. However, there is a need to consider the wall scale in order to also model their sound insulation performances for practical applications [13].…”

Innovative sound absorption technique: Step‐shaped ceramic fiberboards with veneer attachment for walls

“…Examples of such materials include cellulose-based fibers derived from waste wood veneer and agriculture residues, such as cotton, hemp, and jute. [18][19][20][21] However, bio-based sound absorption materials are often highly combustible, and as such, require fire retardants to ensure their safety in building applications. These fire retardants increase production costs and may contain harmful chemicals, which could pose health and environmental risks.…”

“…These materials can be used as sound‐absorbing materials, and they have low environmental impacts and negative health effects. Examples of such materials include cellulose‐based fibers derived from waste wood veneer and agriculture residues, such as cotton, hemp, and jute 18–21 . However, bio‐based sound absorption materials are often highly combustible, and as such, require fire retardants to ensure their safety in building applications.…”
