In the absence of a suitable standard for measuring the reflective thin insulation, the company ALUTHERMO has always collaborated with the scientific world in order to determine the actual performance of its products.
A PRAGMATIC APPROACH
Unlike the measurement of loss through conduction, inapplicable to thin reflective insulation, which is expressed by the theoretical value R (thermal resistance), ALUTHERMO is focused on determining the performance of the different types of insulation in a more real base: measuring the energy consumption.
The principle is very simple: the energy necessary to maintain a reference temperature (21°C) in an insulated construction, alternatively with an insulating ALUTHERMO® and with a “classical” insulator reference in winter conditions.
Roof structure (1) alternatively insulated with Aluthermo Quattro (2), Aluthermo Optima (3), Aluthermo Densima (4) and 200mm glass wool conductivity ? 0.040 W/m.K (5).
OBJECTIVE FIGURES AND CLEAR RESULTS
The structure was placed in an environmental chamber and was subject to winter temperatures of -5°C, 0°C and 5°C while maintaining within thereof a constant temperature of 21°C. The amount of energy required to maintain interior temperature was then measured and compared:
To conclude, it is clear that the thin reflective insulation Aluthermo® presents, under the actual usage conditions, higher perfomances than a classical insulation.
