Wall oven windows made of Resistan can stretch from the oven cavity surface to the cold zone at the door’s edge, as shown in Electrolux’s ICON oven.
move to use transparent glass ceramic in inner wall oven doors is a new
trend Wegert has observed. “With Resistan, designers and engineers can
get very large windows allowing for a greater look inside the oven, an
aesthetically pleasing glass door, and easy cleanup on typically messy
Wegert says if incorporated
correctly into the door, Resistan can withstand “nearly any thermal
gradient a residential oven can throw at it.” Thanks to its
transparency and chemical durability, Wegert adds, some Resistan
materials are also suitable for residential or commercial microwave or
infrared grill applications.
With equally high
heat resistance, SCHOTT’s transparent Robax is used in fireplace and
hearth panels, which allow users to enjoy the fire view and the warmth
while being protected from flying sparks and other fire dangers. “Robax
is an exceptional infrared heat transmitter from a fire. So, in a
high-heat fireplace, the heat generated inside the firebox can be
comfortably felt inside the room while still having a protective buffer
from the fire,” Wegert tells APPLIANCE.
also elevates the combustion efficiency by allowing for a
higher-temperature fire, which is a desired goal of many designs.
“Other glasses would break in this environment due to high thermal
gradients across the glass panel. Cool edges of the glass combined with
an intense flame proximal to the glass center cause most glasses to
fail, but Robax can handle up to 700°C (1292°F) temperature gradients
across the panel,” Wegert says.
designed systems for fireplace use that tap into the thermal robustness
of Robax by adding an infrared reflecting coatings into a glass
package. “These systems provide a cooler external surface so a
fireplace is safer to touch, and also increase the internal combustion
temperature of the fireplace,” Wegert explains. “This increased
combustion temperatures aid in more efficient use of the fuel used,
either wood or gas.”
