Organic fibrous materials are among the promising building materials from the perspective of sustainable development, because easily renewable resources or secondary raw materials are used for their production. Currently, materials based on recycled textile fibers are of increasing importance, especially within the EU with regard to the requirements of Directive (EU) 2018/851 of the European Parliament and of the Council on waste. However, the problem with textiles is their diversity and combination of polymeric a...

The paper is devoted to the study of the combustion process in fibrous organic materials based on natural fibers. The paper presents the results of research focused on the study of the relationship between the microstructure of organic fibrous insulation materials, fiber properties and their resulting reaction to fire. This is a comprehensive approach to describing the reaction to fire beyond the scope of classification according to EN 13501-1. The basic test methods used to determine the reaction to fire are used...

The core insulators of vacuum insulation panels are mostly made from inorganic raw materials with a high SiO2 content, either in the form of nanoparticles or microfibers, while the proportion of organics is usually up to 3 %. The contribution is devoted to the study of reaction to fire in hybrid insulation materials made from a combination of nano SiO2-based particulate raw materials and organic-based fibrous raw materials, where the total proportion of organics is significantly greater than 3 %. Considering that ...

Vacuum insulation panels (VIP) represent a group of super-insulation materials that make it possible to significantly reduce the energy consumption of building structures even in places where it is not possible to build in a greater thickness of insulation. Considering that the consumption of these insulators worldwide is increasing every year, it is necessary to look for long-term sustainable raw material sources, such as easy renewable raw sources. The contribution is devoted to the possibilities of using easy r...

Foam glass is one of the materials for which it is possible to use glass waste of lower quality, which cannot be used for the production of classic glass products. Foam glass aggregate is a very interesting raw material, which, although it does not reach the quality of conventional foamed glass, but has a number of very interesting properties, thanks to which it can be used for the production of composites with a very good ratio of thermal insulation, acoustic and mechanical properties. The paper describes the res...

At present, the consumption of thermal and acoustic insulating materials is increasing worldwide, therefore it is very important to look for possible ways how to produce these materials from secondary raw materials and thus save the primary material base. In the textile and automotive industry, a number of wastes are produced which contain very high purity PES fibers, often comparable with primary PES fibers. In general, most types of PES fibers used in industry have a very low thickness (between 10 and 20 microns...

In building materials, under reduced pressure, a significant improvement in thermal insulation properties occurs due to the elimination of conduction and flow through the gas phase filling the pore system of insulators (in case of the most insulators). This effect is used in the manufacture of vacuum insulating panels. In earlier times, vacuum insulating panels have only been produced with glass wool or SiO2 based insulators, but alternative insulating panels have also begun in recent years. These insulators are t...

The paper deals with the possibilities of using textile waste in the form of synthetic and natural fibers for the production of thermal and acoustic materials. The paper presents the results of the research that confirm that the waste fiber insulators can show more favourable properties in some areas than conventional synthetic insulators commonly used in the building industry. The advantage of insulators from waste textile fibers is their high variability. In the field of them insulation properties, these insulat...

This paper described results of the research in the field of organic based raw materials from the textile industry for the production of vacuum insulating panels (VIP) with extremely low thermal conductivity value. The paper presents current research findings on the behavior of fibrous structures on an organic basis at extremely low pressure. The practical findings and results of experimental work on the production and behavior of vacuum insulating panels with an alternative core insulant based on organic / natura...
