“…Being an excellent thermal insulating material, rigid polyurethane foam (RPUF) has been widely used in the field of thermal insulation in building envelopes to save energy due to their M a n u s c r i p t low thermal conductivity, superior specific mechanical properties and low density [3][4]. As traditional blowing agents, CFCs and HCFCs have been phased out in developed countries and will be totally banned by 2020 in developing countries according to the Montreal protocol, which led to an important research focus on foam synthesis modification using HFC-245fa, HFC-365mfc, cyclopentane and water as new generation of blowing agents [5][6][7][8]. Owing to the inherent drawbacks in these environmentally friendly blowing agents, the mechanical and thermal performance of the new generation of foam products are not as good as traditional foams.…”

“…To overcome this problem, in the scientific and technological literature, there can be found numerous strategies aimed to the increase of the mechanical properties of PU foams, mostly by filling the polymeric matrix with a rigid phase. Reinforced PU foams have been prepared with several kinds of fillers, such as glass fibers [3,4], nano-silica [5,6], wood flours [7], clays [6,8], and carbon powder [9]. These studies point out the problem of adhesion between the polymeric matrix and the filler for mechanical applications.…”

“…Hence, the fiber effect of cryogenic heat transfer cannot easily occur along the Z-direction. According to one of previous studies related to thermal conductivity of RPUF [9], it was confirmed that the thermal conductivity of RPUF increases as the glass fiber content increases. For this reason, the upper and lower surfaces of the RPUF, which are perpendicular to the foaming direction, are connected to the cryogenic heat resources.…”
