Thermal panel insulation speaks to what is thermal panel insulation and why thermal panel insulation in general.
It is defined as material that is added to a building structure to slow the conduction of heat through the building. In North America and other cold climates insulation is almost always installed in roof and exterior walls, in floors over unheated spaces, around foundations and concrete slabs on grade and other areas where heated or cooled zones come in contact with unconditioned zones, the earth or outside.
A well insulated building increases occupant comfort and reduces the energy required to control the inside ambient environment.
Thermal resistance is the term used in speaking of a materials ability to resist heat conductance and is known as the R factor which states the square foot hour degree F per BTU. In the metric system the thermal resistance is known also as RSI or R and is expressed as square meter degree Kelvin per watt.
Am insulating factor of R-1 is equal to the metric RSI of 0.176. There are lists of common insulating materials and their R factors available. The higher a material’s R factor the higher its resistance to heat flow and the better it is as a thermal insulator.
The thermal performance of a building is dependent on the sum of the thermal resistance of the material used in its construction. All components of a structure contribute the overall thermal resistance and the amount of the contribution depends on the type of material and its thickness. Metals are poor insulators with concrete and masonry being slightly better with wood being better. In conventional walls and roofs most of the thermal resistance comes from the insulation materials used.
In wintertime, it is warm inside a heated building and cold outside and the inside surface of a wall or roof assembly is warm, and the outside surface is cold. Between the two surfaces, the temperatures vary according to the thermal resistances of the various layers of the assembly. Due to the fact that most of the insulating value of the assembly is in the insulation itself, most of the temperature changes within the building occurs across the thickness of the insulating material.
Thermal insulation for a low slope roof may be installed below the structural deck, between the deck and the membrane or above the membrane.
