“…The plant and animal based natural fibers ability, to work as insulating materials depend on the capability to trap the air in the fiber cavity, inside it or in the fibers matrix, notably in the case of fiber insulation panels, for example the sheep wool fiber insulation panel (Ahmed et al, 2019) and formation of compact insulating layers in cases where fibers are mixed with binders (Valenza et al, 2015).…”

Old masonry buildings represent the largest part of traditional constructions. Generally, they are both seismically vulnerable and thermally dispersive. Therefore, the need for seismic and thermal retrofitting aimed at reducing their vulnerability and environmental impact has motivated research efforts towards sustainable retrofitting solutions. This study presents a literature review of the approaches currently available for masonry retrofitting. Specifically, it highlights the use of fiber in textile form i.e., Textile Reinforcement Mortar (TRM), as Fiber Reinforced Polymer (FRP) and natural fibers (animal and plant sources) to masonry retrofitting. In addition, specific attention is devoted to the integrated (structural and thermal) fiber-based integrated retrofitting techniques that are becoming very important in the last years.

“…Analisis termogravimetri (TGA dan DTGA) menunjukkan bahwa degradasi dan dekomposisi serat dimulai pada 232 C dengan sampel kehilangan hanya sekitar 8,5% dari massa aslinya. Analisis differential scanning calorimetry (DSC) dilakukan dan menunjukkan bahwa transisi endotermik dimulai pada sekitar 243-382 C dengan puncaknya pada 369 C. Selain serat alam, analisis termogravimetri dan analisis differenial scanning calorimetry untuk bulu domba, kambing, dan ekor kuda telah dilaporkan [26].…”

Pemakaian material insulasi termal pada bangunan menjadi topik penting dalam upaya efesiensi konsumsi energi listrik. Material insulasi termal berbasis serat alam menjadi alternatif dari serat sisntetis yang banyak digunakan sekarang ini. Kestabilan termal material pembentuk menjadi penting untuk diketahui sebagai dasar kelayakan sebagai material insulasi termal. Kayu kelapa sawit (KKS) dan serat rami (SR) mempunyai potensi sebagai bahan baku material insulasi termal dari serat alam. Penelitian ini bertujuan untuk mengkaji stabilitas termal kayu kelapa sawit dan serat rami sebagai bahan baku material insulasi termal berbasis serat alam. Partikel kayu kelapa sawit dan serat rami mendapat perlakuan sebelum diuji. Kayu kelapa sawit direndam dalam air panas 100 0 C selama 30 menit dan serat rami dalam larutan NaOH 5% dengan waktu yang sama. Pengujian thermogravimetric analysis (TGA) dan diferensial scanning clorimetry (DSC) dilakukan untuk mendapatkan karakteristik termal kedua bahan baku. Pengujian dilakukan untuk kedua serat, tanpa, dan dengan perlakuan. Pengujian TGA menghasilkan KKS dan SR dengan perlakuan memiliki kestabilitas termal yang lebih baik dibandingkan KKS dan SR tanpa perlakuan. KKS dan SR dengan perlakuan memiliki kestabilan termal maksimal temperatur 377 0 C dan 399 0 C. Analisis DSC dari KKS dan SR dengan perlakuan memperlihatkan temperatur puncak pada 409 0 C dan 408 0 C. Stabilitas termal serat akan meningkat dengan perlakuan dibandingkan serat tanpa perlakuan. Kata kunci : Material insulasi termal, kayu kelapa sawit, serat rami, TGA, DSC Study of the thermal stability of raw materials for thermal insulation materials based on natural fibers: palm wood and ramie fiber

Thermal insulation has great potential to reduce energy consumption in buildings. This study aims to provide a general perspective by addressing the thermal insulation materials used throughout the history of the construction industry and to understand the current situation with developing technology. The literature review was used as a method in the study. The insulation values of current thermal insulation products were investigated and compared. An energy loss and gain analysis were carried out on the Revit model to understand the difference between the widely used rock wool and a nanotechnology product, aerogel-added thermal insulation material. The results of the study show that thermal insulation materials produced with nanotechnology examined have lower thermal conductivity coefficients compared to other thermal insulation materials. According to the analysis carried out on the Revit model, the thermal insulation material with aerogel provides 8% savings in cooling loads compared to the use of rock wool. Developing competitive and sustainable materials is of the utmost importance. The literature review suggests that new composite insulators can be produced by combining suitable materials.
