BTU Technologies Patents R-value-Improving Technology

BTU Technologies LLC has developed and now patented a unique technology for substantially improving the edge-to-edge R-value of insulated glazing units fabricated with stainless steel and aluminum spacer tubes.

Recent third party testing of resistance to interlayer heat flow (R-value) has demonstrated a 12 degree Fahrenheit improvement in glass surface temperature at the interior side sightline of a BTU Technologies IG unit, fabricated with a Phase Change Material (PCM) charged stainless steel spacer.In this comparative testing, both the PCM charged and conventional IG test specimens are simultaneously exposed to an interior/exterior temperature gradient of 0 and 70 degrees Fahrenheit, respectively, and the 12 degree Fahrenheit temperature differential reflects a reduced loss of interior heat to cold conditions on the exterior of the IG test units. (Please note that the PCM charged & conventional IG test specimens are fabricated around identical raw stainless steel spacer tubes).

At minimum, these results represent a 50 percent improvement in resistance to heat-loss performance over the highest performing, currently available, “warm-edge” IG spacer systems in a dual pane IG configuration. By enabling superior heat-flow performance from a metallic spacer tube based glazing system, large scale IG structural characteristics are maximized and traditional manufacturing processes are preserved while productivity and manufacturing costs remain highly competitive. The specified materials of this technology are non-toxic, not a fire hazard, are unrestricted by DOT, do not change volume or affect visual clarity. The technology is self-contained and self-regulating. The specified PCMs are low cost and supplies are extremely scalable.
