the appropriate Solution for
Insulation by reflection
Insulation based on reflection is not a recent discovery. The principle has been very successfully implemented in thermos flasks and allows liquids to retain their temperature for a very long time. The extent to which a product is insulated is expressed using a so-called R-value, which indicates thermal resistance. If a material has a high R-value, it will offer better thermal resistance, and vice versa. The R-value is determined by how effectively heat transfer via conduction, convection and radiation is prevented.
Reduce heat loss
By reflection
Most architectural constructions feature several layers of materials, possibly separated by an air cavity. When an air cavity is present, heat resistance is determined based on resistance against transfer by reflection, convection and conduction. The effect of these three types of heat transfer, together with the level of insulation per type of transfer, is used to determine total resistance. It is thus determined by many factors. In any case, air cavities encounter very little heat transfer via flux and conduction. Heat loss primarily takes place via radiation.
All materials radiate heat. The exact level of radiation is not only determined by the temperature of the surface, but also by the material itself. The latter is expressed as an emission coefficient. Most construction materials, like e.g., bricks, concrete and wood, have a high emission coefficient and thus radiate heat quite easily. In other words: such materials lose their heat relatively easily due to heat transfer via radiation.
The reflective materials of Meuwissen Gerritsen actually have a low emission coefficient. As a result, emissions via construction materials can be reduced considerably when these materials are used. According to the laws of physics, materials with a low emission coefficient are very effective at reflecting heat radiation. For instance, the aluminium incorporated into Miofol® 170 AG, Alkreflex 2L-2, Polytex 145 AG and Miofol® 150A reflects over 90% of such heat radiation.
In buildings, heat that is lost via conduction or convection represents circa 25% of overall heat loss. The majority of this heat loss, namely 75%, takes place via radiation. As a result, all types of heat transfer must be taken into account to ensure energy-efficient construction. Are you curious about how you can build even more efficiently?
