NEW SGEM Scientific Online eLibrary
After a long time work, our pride is the absolutely new SGEM Online eLibrary, available here. The Library is created according the rules of the International databases, with a whole needed information and ability to export the article in BIB format. Try and spread your experience with us.
Till we complete the new library with papers from all the years, you can use this link /Full Old Library/, if papers that you need are not visible yet here.
SHEEP WOOL HEAT INSULATION SUSTAINABILITY
Hegyi, A.; Szilagyi, H.; Lazarescu, A.; Meita, V.; Sandu, M.
Sustainability is a criterion defined since the 1980s, essential in all areas of activity, without which development cannot be acheived. Thermal insulation mattresses produced using sheep wool, successfully meet the conditions imposed by this criterion. This type of building material ensures the responsible use of non-renewable natural resources, the possibility of reuse and recycling of materials, contributes to environmental protection and pollution reduction, energy saving and provides a hygienic and healthy living climate. This paper analyzes how sheep wool mattresses meet sustainability requirements, simultaneously with compliance with specific requirements in construction based on the criteria of regulation (EU) no. 305/2011 of the European Parliament and of the Council of 9 March 2011 laying down harmonised conditions for the marketing of construction products. At the same time, the physical and mechanical performances of 20 types of sheep wool mattresses, from 7 manufacturers, available on the international market, are presented. This identifies the strengths of these products (thermal insulation performance, low overload of the structural strength of buildings due to low density, low environmental impact and contribution to improving indoor air quality), as well as weaknesses (high water absorption, low mechanical strength, which make it difficult to use outside buildings, requiring either indoor location, additional protection measures for outdoor location). However, cumulating all these aspects, it can be said that sheep wool mattresses are a good heat-insulating material, which successfully meets the requirements of sustainable development, the benefits in terms of environmental impact and quality of life recommending them as a possible substitute for some sintering heat-insulating materials, highly polluting and hardly or not at all biodegradable.
