Package solution for modern high performing systems
A system loses heat through three primary modes: conduction, convection, and radiation. Optimized insulating systems can minimize heat loss by targeting all three heat transfer modes at once. Heat transfer through a system is quantified by an Uf value, with lower Uf values indicating better insulation. However, some applications may have a required Uf value that necessitates wide insulating strips to reduce the conduction. The wider the insulating strips, the more heat transfer would occur by convection as a result of freely-flowing air.
Technoform’s standard 2-strip system is connected using webs to reduce convection while increasing rigidity. The central web minimizes heat transfer by breaking up a single large cavity into smaller cavities reducing the convective effect of moving air. Also by connecting the strip, the system obtains more torsional rigidity.
The package solution increases the structural rigidity of the insulation zone while decreasing the amount of heat transfer that would occur by conduction, convection, and radiation. Systems using this unique solution have yielded Uf values of 1.4 W/m2K (0.25 BTU/hr ft2 F).
