The Effective Thermal Conductivity of Various Forms of Urea-Formaldehyde Foam

摘要: The thermal conductance of vertical panels was measured using the Guarded Hot Box Method in order to compare various forms urea-formaldehyde foam used fill cavities panels. These included preshrunk and fitted, foamed place, shredded blown. Age studies were performed on with urea- formaldehyde which place. increased time for these because shrinkage cracking foam. showed an increase as density material decreased. Preshrunk that smaller than cavity panel is dependent upon placement Polyethylene wrapped, blown excellent insulation characteristics.
