what is thermal insulation?
107432
Thermal insulation is the reduction of thermal conduction to a point where it reduces the flow of energy from one system to another.  In laymans terms, you have a flow of energy (usually in Btu/s or J/s aka Watts), between two systems of different temperatures.  By isolating the systems from each other with an insulator, you are slowing the transfer of heat and energy from one system to another. \nThat is the goal of an insulator - reducing (slowing) the rate of heat transfer.

thermodynamics?  heat transfer?  physics?

Err.. can you please be  more specific onyour question? Your question is very general cover from :\n\n1. Material Defect\n2. Insulation Defect\n3. testing incompliancee\n4. ...

there are alot of factors involved in heat loads.go to ASHRAE{1981}conditions include storage size,outside surface area,inside dimensions,volume,insulation.ect ect go to what i said here you should  find all you want to know

Are you asking about thermal conductivity or specific heat?\nAnd why are you not doing the research you should be doing:\nhttp://www.engineeringtoolbox.com/specific-heat-metals-d_152.html\nhttp://www.engineeringtoolbox.com/thermal-conductivity-metals-d_858.html

strange situation.. anyway why you dont use thermal tape ,, its strong enough to prevent any leak

hey hey. finally something i know about.\n\nInsulation? by that i think you refer to the resistance on heat traveling from one area of a building to another (or from outside to inside)? well, i have heard of, fibreglass woll. spun molten rock wool, polystyrene, etc. if you are refering to building materials used by varying cultures around the world, then i would say, mud walls. clay walls, logs, stone, thatch (roofing), straw (hay), ice (igloos). If im not on the right track, im me and ill tell you other stuff

In physics, heat is defined as energy in transit. Generally, heat is a form of energy associated with the motion of atoms, molecules and other particles which comprise matter. Heat can be created by chemical reactions (such as burning), nuclear reactions (such as fusion taking place inside the Sun), electromagnetic dissipation (as in electric stoves), or mechanical dissipation (such as friction). Heat can be transferred between objects by radiation, conduction and convection. Temperature, defined as the measure of an object to spontaneously give up energy, is used to indicate the level of elementary motion associated with heat. Heat can only be transferred between objects, or areas within an object, with different temperatures.

It is possible, Human hair has good thermal insulation properties. The only problem, I can think of is the flammability of human hair.

sun bathing is radiation. sun radiation travel through space(no air in space so it is pure radiation energy transfer), travel through air (in there also radiation is dominant ) then get in to your skin\n\nstroform is a good insulater. it has hollo set of chambers. in chambers covection can be done but cells prevent transfer of air further and convection is stoped. in the other hand conduction is prevented due to poor conductivity of material. radiation is not a problem when heat difference is not too much high and because radiation generated from a object is is propotional to absolute heat  of the object. in case of very high temperature allumenium foil is used to limit radiation.

What you really are measuring is insulating capacity. You can probably measure the temperature rise in a container full of a given volume of water at a fixed initial temperature, and wrapped in one or more layers of the fabric in question. The better-insulating fabrics will keep you warmer.

Thermal energy is the kinetic energy and potential energy of the molecules. Temperature is a measure of the average kinetic energy per molecule.\n\nThe term "Heat" as uesd in this answer will refer to the change in the thermal energy of an object; thus the expressions "heat transferred" or "heat absorbed". A device used to measure temperature is called a thermometer.

do you mean icynene?\nif so it is a foam insulation sprayed into walls, ceilings, etc\nGood Luck

There are such values, called R-values.  They define the resistance to heat loss per unit time, temperature difference and area (i.e., higher is better).  These are English units, hour-degreeF-ft^2/BTU.  An R-value of 20 means that 100 sq. ft. of wall separating a 20 deg F temperature difference for 8 hours passes 800 BTU of heat.  Typical recommended R-values (ref. 1) for use in residences are 4 to 60, depending on climate and location in the house.  For walls the range is 11 to 28.  In the ref. 2 web site you can find R ratings for various insulation materials, in R-value per inch of insulation thickness, and thicknesses required for various recommended R-values.
