Thinsulate is a brand of synthetic fiber thermal insulation used in winter clothing. The word is a portmanteau of the words thin and insulate , trademarked by 3M. [ 1 ] The material is made by the 3M Corporation and was first sold in 1979. [ 2 ]
This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.
Sufficient thermal insulation is the fundamental task that ensures a healthy indoor environment and against structure damages [10]. It is also a key factor in dealing with high energy consumption, it can reduce the heat flow through the building envelope. Good thermal insulation can also bring the following benefits to the building:
The interplay of heat and sound is applicable in both conversion ways. The effect can be used to produce acoustic oscillations by supplying heat to the hot side of a stack, and sound oscillations can be used to induce a refrigeration effect by supplying a pressure wave inside a resonator where a stack is located. In a thermoacoustic prime mover ...
A close-up image of acoustic foam. Acoustic foam is an open celled foam used for acoustic treatment. It attenuates airborne sound waves, reducing their amplitude, for the purposes of noise reduction or noise control. [1] The energy is dissipated as heat. [2] Acoustic foam can be made in several different colors, sizes and thickness. [3]
