The paper presents some aspects of an experimental research in which basic recipes have been designed in order to obtain innovative products to be used in construction as finishing coatings. Starting from sunflower seed shells, considered a waste rather a by-product resulting from the industry of edible sunflower oil, and also from rough sheep wool, an animal waste from the zootechnical field, and also from the specific thermal insulating characteristics of theese two waste materials, a serie of basic recipes was made. Three types of innovative composite materials resulted, each of them having a continuous component, as a binder, consisting of a film-forming product based on a sinthetic resin, as well as a discontinuous component, made of sunflower seed husks with maximum dimensions of 4 mm and sheep wool yarns of about 3-5 mm length. After being applied in 4 layers on drywall surfaces, each of the three composite materials generated a coating with good characteristics after testing for thickness, adhesion to drywall and thermal conductivity, even if much thinner than traditional thermal isolating building materials. The novelty of the research is, on the one hand, the original nature of the resulting coating material, a coating with an atypical but aesthetic appearance and good characteristics as finishing when the material is applied in a multi-layered system. On the other hand, obtaining such a type of composite material can be a new method for integrating this kind of vegetal and animal wastes in construction, thus generating new products with high added value.
