Drawn and cast composite profiles with polymer-matrix have in present time a non-replaceable position on the building products market, especially for special applications, where they successfully replace conventional materials and surpass them in properties. Involved are for instance applications of composite materials in surroundings with heavy corrosive load or structural members with high strength values and low mass which in shape variety and in possibility of being dyed through comply with particular esthetic points of view. The examined composite profiles and panels are prepared by pulltruding method. The binder is a polyester or vinylcster resin and as reinforcement oriented glass or sometimes carbon fibres and flat reinforcements are used. In spite of very good experience with this material and with particular products some physical-mechanical properties of polymer-composites are not yet verified in present time. In the paper the test results of these polymer-composites under normal temperature and under thermal load are presented.
