Thermotech's most energy-efficient windows include silicone foam Super Spacers™, triple panes, and low-eLow-emissivity coating. Very thin metallic coating on glass or plastic window glazing that permits most of the sun’s short-wave (light) radiation to enter, while blocking up to 90% of the long-wave (heat) radiation. Low-e coatings boost a window’s R-value and reduce its U-factor. glazingWhen referring to windows or doors, the transparent or translucent layer that transmits light. High-performance glazing may include multiple layers of glass or plastic, low-e coatings, and low-conductivity gas fill. (Pilkington or AFG), resulting in some of the highest-performance windows in North America (many glazing options produce window unit U-factors below 0.20). Thermotech promotes the use of different glazings on different orientations to optimize energy performance. The company offers up to four different IG (insulating glass) options per project. Other features include: 15% post-industrial recycled-content fiberglass frames, near-zero-solvent waterborne paint, offcut-sourced polystyrene insulation, and river-bottom-recovered pine jamb extensions.
