<p>Porous insulation board Porous insulation board, as the name suggests, is that the board itself has a lot of pores, and the heat dissipation function mainly passes through these pores; because of the existence  australia wood decking of pores, the ability of the air in the pores to conduct heat is reduced. Not only can it be insulated, but it also has a very good insulation effect. XPS extruded insulation board is made of polystyrene resin, mixed with other chemical auxiliary materials, mixed by heating, injected into the catalyst, and finally extruded.</p><p> As a rigid foam board, it has a very regular closed-cell honeycomb structure. This structure has a  consumer reports evergrain composite complaints natural advantage in that it can effectively prevent the penetration of steam water molecules, thereby blocking the heat conduction. The ultra-low thermal conductivity also makes it an efficient material for insulation, and it is not prone to aging. Heat-reflecting insulation board Heat-reflecting insulation board is a kind of board which is insulated by reflection. It has a very high reflection coefficient and is able to reflect most of the heat. The main reason is due to the addition of some metal elements inside. Such as: nickel, aluminum foil and other metals. Phenolic roof insulation board Phenolic  restore an antique park bench in denver insulation board is a kind of board which integrates fireproof and heat preservation effect. </p>
