glass will generally not leave the opening.
- 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
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.
