The invention relates to a method for maintaining the temperature of fluid media in pipes even in the event of an interruption of the fluid media flow. In a first step, a heat reservoir layer (1) is produced comprising a latent heat reservoir material (2) and a matrix material (3). In a second step, the heat reservoir layer (1) is either arranged around a pipe (4) and subsequently encased with a heat damping material (5) or the heat reservoir layer (1) is brought into contact with heat damping material (5), whereby a heat reservoir damper composite (51) is obtained, and the pipe (4) is then encased with the heat reservoir damper composite (51) such that the heat reservoir layer (1) of the heat reservoir damper composite (51) lies between the pipe (4) and the heat damping material (5) of the heat reservoir damping composite (51).

A filled trench is disclosed. The filled trench comprises: a pair of conduits (3a, 3b) for delivering fluid with a different temperature in each of the conduits (3a, 3b), the pair of conduits (3a, 3b) being surrounded by filling material; a first section (5a) filled with a filling material of a first type (4a), wherein the first filled section (5a) of the filled trench occupies a space in between the pair of conduits (3a, 3b); and a second section (5b) filled with a filling material of a second type (4b). The filling material of the first type (4a) has a first thermal conduction coefficient and the filling material of a second type (4b) has a higher second thermal conduction coefficient. Further, a method for filling such a filled trench is disclosed.

A thermal insulating structure comprising a top, a bottom, first and second sides, a thermal insulating material, and a first transverse member is contemplated. The thermal insulating material is disposed between the first and second sides. The first transverse member comprises a plurality of apertures, which thereby provides less material of the transverse member for heat transfer compared to an identical transverse member with no apertures. Thus, the path for heat transfer through the first transverse member is restricted and the effect of an undesirable “hot spot” is reduced or eliminated.

A length of a main pipe is provided. The main pipe has an internal surface and an external surface. A plurality of channels, tubes or conduits is attached to the external surface of the main pipe and spaced about a circumference thereof. A spray foam insulation is applied to the external surface of the main pipe. Prior to curing the spray foam insulation, a compressive force is applied against an exposed outer surface of the spray foam insulation to prevent a bulge from forming over the channels, tubes or conduits so that the outer surface of the insulation has a uniform radius.

An insulation product may include an insulation material. The insulation material may include at least one material selected from the group consisting of nonwoven insulation, aerogel insulation, mineral insulation, and foam insulation. The insulation material may include a first end and a second end positioned opposite the first end. The first end may include a protrusion. At least a portion of the protrusion may widen in a direction opposite the second end. The second end may define a cutout that substantially matches a size and shape of the protrusion. The cutout and the protrusion may be aligned with one another along a length of the insulation material.
