Insulation granules

First ply or as vapor barrier under insulation. Coated on both sides with asphalt and surfaced on top side with fine mineral granules (2,9). 

After it is washed, dried, and granulated, this silica gel has a very high specific surface area (about 700 m2-g 1) and is useful as a drying agent, a support for catalysts, a packing for chromatography columns, and a thermal insulator. 

Plywood adhesive, 48% fibrous and granulated wood adhesive, 16% insulation adhesive, 13% laminate adhesive, 6% molding compounds, 5% foundry adhesive, 3% miscellaneous, 9%... 

A simple consideration of granular metals in the framework of the classic percolation theory when granules are treated as metal balls, embedded into insulating material, appears to be very limited. Taking into account quantum effects and, first of all, possibility of the tunnel transitions between nanogranules leads to the change in parameters of the percolation theory and even to diminishing of the percolation threshold [15,38,39]. Even in... 

However, the shape of metal granules does not strongly differ from spherical one for significantly large number of metal-insulator granular... 

An example of heat transfer through a porous medium is heat transfer through a layer of granular insulating material. This material will be saturated with air, i.e., the space between the granules of insulating material is entirely filled with air, and this air will flow through the insulation material as a result of the temperature difference imposed on the material, i.e., there will be a free convective flow in the porous material. Even when a fibrous insulation is used, the flow in the insulation can be... 

There are a wide variety of insulation materials available in the market, but most are primarily made of fiberglass, mineral wool, polyethylene, foam, or calcium silicate. They come in various trade names such as granulated bulk mineral wool insulation, cork insulation sheets, foil-faced fiberglass insulation, blended sponge rubber sheeting, and numerous others.
