Comparative experimental analysis of the fire resistance of sandwich panels with polyisocyanourate core reinforced with fiberglass fabric

Sandwich panels are systems with structural functions that used in the field of civil construction, currently, they construction buildings and also as cladding for walls, ceilings, among others. This article shows results an experimental comparative analysis behavior fire resistance two sandwich function composed Polyisocyanurate (PIR) foam core fiberglass-reinforced fabric dimensions 3150 mm × 2800 x 150 mm. The first-panel system on its face exposed to was coated plaster plates while other ceramic plates. parameters subject comparison both were stability, tightness, thermal insulation. For this, test carried out evaluating each Samples subjected exposure compare other. According obtained this research, materials shape panel structure coating material influence resist behavior. Thus, study plasterboard-coated showed better performance against evaluated a long time than ceramic-plated system, checking insulation benefits protection qualities plaster.
