- Laminating
- A
method of gluing strips of thin clear wood to the lengthwise surfaces
of finger-jointed material to provide the appearance of clear stock.
- Low
E Glass
- Low
E stands for low emissivity. The lower the emissivity, the higher the
percentage of long-wave radiation blocked, thereby improving thermal
performance. Low E glass is coated with a thin microscopic, virtually
invisible metal or metallic oxide layer. The primary function is to
reduce the U-Value by suppressing radiative heat flow. A secondary
feature is the blocking of short wave radiation to impede heat gain.
