Los perfiles existentes, y los paneles sándwich, con aislamiento de masa incorporado, están suficientemente documentados, en cualquier consulta de los catálogos comerciales de los fabricantes existentes (Arcelor, Hiansa, Gonvarri, Alfonso Gallardo etc .). Problema técnico:  The existing profiles, and sandwich panels, with built-in mass insulation, are sufficiently documented, in any query of the commercial catalogs of existing manufacturers (Arcelor, Hiansa, Gonvarri, Alfonso Gallardo etc.). Technical problem:
Los perfiles existentes de diversos tipos de chapa simple con distintas morfologías y acabados tienen altísimos valores de transmisión térmica, y una gran capacidad de acumulación, cuando el calor incide sobre estos perfiles aumentan su temperatura por encima de la temperatura incidente, disipando el calor por convección por ambas caras del perfil, cuando la temperatura exterior disminuye, se alcanza de forma casi inmediata el punto de equilibrio, con los valores de la zona más fría. The existing profiles of various types of simple sheet with different morphologies and finishes have very high thermal transmission values, and a great capacity of accumulation, when the heat affects these profiles increase their temperature by above the incident temperature, dissipating heat by convection on both sides of the profile, when the outside temperature decreases, the equilibrium point is reached almost immediately, with the values of the coldest zone.
Los paneles aislantes también de distintas tipologías de chapa y distintos materiales y espesores de aislamiento, plantean problemas de complejidad de fabricación, (En una línea de panel, de desenrollan dos bobinas simultáneamente colándose entre ambas espuma rígida de poliuretano de distintas tipologías y densidades) también pueden tener alma aislante de espumas rígidas de poliestireno expandido ó de lana de roca, cuando se requieren paneles ignífugos; como llevan incorporados aislantes de masa donde se requieren distintos espesores, supone costes importantes en la logística de distribución del mismo, por su volumetría. La composición típica de un panel aislante con dos chapas de acero conteniendo un núcleo aislante, generalmente derivado del petróleo supone que sea un producto intrínsecamente caro, con un precio de coste de materiales tendente al alza. El perfil de chapa exterior del panel sándwich ó panel aislante, como explicamos anteriormente para el perfil ó chapa simple, cuando recibe calor solar, tiende a aumentar su temperatura superficial, por encima de la temperatura exterior incidente, aumentando el valor del salto térmico, obligando a recalcular al alza los espesores teóricos necesarios del aislamiento del panel.  The insulating panels also of different types of sheet and different materials and thicknesses of insulation, pose problems of manufacturing complexity, (In a panel line, two coils unwind simultaneously between both rigid polyurethane foam of different types and densities) also they can have an insulating core of rigid foams of expanded polystyrene or rock wool, when fireproof panels are required; As they have incorporated mass insulators where different thicknesses are required, it implies significant costs in its distribution logistics, due to its volumetry. The typical composition of an insulating panel with two steel sheets containing an insulating core, generally derived from petroleum, assumes that it is an intrinsically expensive product, with a price of upwardly cost of materials. The outer sheet profile of the sandwich panel or insulating panel, as explained above for the profile or single sheet, when it receives solar heat, tends to increase its surface temperature, above the incident outside temperature, increasing the thermal jump value, forcing to recalculate the necessary theoretical thicknesses of the panel insulation.
La chapa obtenida en el mismo proceso fabril y preparada en bobinas ó chapa lisa, se utiliza también en la manufactura de tubos, siendo el aislamiento posterior de los mismos muy complejo.  The sheet obtained in the same manufacturing process and prepared in coils or smooth sheet, is also used in the manufacture of pipes, being the subsequent insulation of them very complex.

(Figure 2). Description of the theoretical behavior of thermal insulation
La transmisión térmica es unidireccional, va de la parte más caliente a la más fría, hasta alcanzar una temperatura de equilibrio. Los procesos de transmisión del calor por medio del contacto directo de las moléculas del material, son la conducción y la acumulación. Para el cálculo teórico del flujo unidireccional en estos procesos, se aplica la Ley de Fourier. Cuando el flujo de un ambiente se pone en contacto con una superficie de temperatura distinta, el proceso de transmisión de calor se denomina convección y obedece a la Ley de Newton sobre el enfriamiento, estas formas de transmisión del calor, se producen de forma simultánea y concurrente, de manera que en situaciones reales, e incluso en condiciones de laboratorio, es difícil discernir con exactitud la contribución de cada mecanismo en la transmisión de calor entre distintos gradientes de temperatura a través de un paramento. The thermal transmission is unidirectional, it goes from the hottest to the coldest part, until it reaches an equilibrium temperature. The processes of heat transmission through direct contact of the molecules of the material are conduction and accumulation. For the theoretical calculation of the unidirectional flow in these processes, the Fourier Law is applied. When the flow of an environment comes into contact with a different temperature surface, the process of heat transfer is called convection and obeys Newton's Law on cooling, these forms of heat transmission occur simultaneously and concurrent, so that in real situations, and Even under laboratory conditions, it is difficult to discern exactly the contribution of each mechanism in the transmission of heat between different temperature gradients across a wall.
En el intercambio de calor entre dos gradientes donde se solapan los flujos debidos a la radiación, se considera la contribución de la absorción infrarroja de onda corta y alta frecuencia, ya sea procedente del sol o del alumbrado, y la de onda larga ó de baja frecuencia, procedentes de las superficies del entorno e incluso, en el caso de recintos cerrados, existirían radiaciones infrarrojas emitidas por el entorno y reflejadas por el resto de los paramentos, para el cálculo teórico de la radiación se utiliza la ley de Stefan- Boltzman.  In the exchange of heat between two gradients where the fluxes due to radiation overlap, the contribution of short-wave and high-frequency infrared absorption, whether from the sun or lighting, and long-wave or low-wave, is considered frequency, coming from the surrounding surfaces and even, in the case of closed enclosures, there would be infrared radiations emitted by the environment and reflected by the rest of the walls, for the theoretical calculation of the radiation the Stefan-Boltzman law is used.
La conductividad térmica de la mayoría de los materiales considerados como aislantes, excluyendo a los reflexivos, ó los que en su momento, emplearon gas freón (poliuretanos) radica en el aire inmóvil contenido en su interior, las microesferas de cerámica tienen capacidad aislante tanto reflexivo, como de masa por el vacío interior de la microesfera, para lo cual se precisa un espesor medio de 0,5 a 2 mm. o más rebajando además en lo posible el espesor de la pared de la microesferas, también tendrían cierta capacidad aislante si son macizas..  The thermal conductivity of most of the materials considered as insulators, excluding the reflective ones, or those that at the time used freon gas (polyurethanes) lies in the still air contained inside, the ceramic microspheres have insulating capacity both reflective , as of mass due to the internal vacuum of the microsphere, for which an average thickness of 0.5 to 2 mm is required. or even further reducing as far as possible the thickness of the microsphere wall, they would also have some insulating capacity if they are solid.
Según el Sistema Internacional de Unidades (SI) Se considera a un material aislante térmico, cuando su coeficiente de conductividad térmica λ (Lambda), que se define como la cantidad de calor, que atraviesa en la unidad de tiempo, una superficie de 1 unidad de área y 1 unidad de espesor, de una muestra de extensión infinita y caras plano/paralelas y cuando las temperaturas de ambos difieren en 1°C, sus unidades en el SI, serán el W/m-°K, que equivale en el Sistema Técnico 0,86 kcal/m-h-°C y en el sistema anglosajón a 0,577 Btu/ ft*h*°F, es inferior a 0,10 W/m-°K, medido a 20 °C, ó en el Sistema Técnico, a 0,086 kcal /m-h- °C y en el anglosajón a 0,0577 Btu/fh*h*°F como la chapa metálica se mueve en un rango de conductividad térmica de 300-400 w/m°K con la adicción de las partículas de cerámica que tienen una conductividad térmica media de λ^Ο,ΙΟ- 0,20W/m-°K> a 25°C,. mejora de forma sustancial el coeficiente de transmisión térmica de los soportes metálicos tratados.  According to the International System of Units (SI) A thermal insulating material is considered, when its coefficient of thermal conductivity λ (Lambda), which is defined as the amount of heat, which crosses in the unit of time, an area of 1 unit of area and 1 unit of thickness, of a sample of infinite extension and flat / parallel faces and when the temperatures of both differ by 1 ° C, their units in the SI, will be the W / m- ° K, which is equivalent in the Technical System 0.86 kcal / mh- ° C and in the Anglo-Saxon system at 0.577 Btu / ft * h * ° F, is less than 0.10 W / m- ° K, measured at 20 ° C, or in the System Technical, at 0.086 kcal / mh- ° C and in the Anglo-Saxon at 0.0577 Btu / fh * h * ° F as the sheet metal moves in a range of thermal conductivity of 300-400 w / m ° K with the addiction of ceramic particles having an average thermal conductivity of λ ^ Ο, ΙΟ- 0.20W / m- ° K> at 25 ° C ,. substantially improves the thermal transmission coefficient of the treated metal supports.
