Prices given on other pages are for double-pane, clear, tempered glass units. The following % amounts are multiplied to the double-pane base costs. |
Low-Emissivity Glass (Low "E") - With Low Emissivity coatings, solar energy (short wave radiation) is transmitted through the insulating unit to the building's interior, where it is absorbed by carpeting, furniture, walls, etc. It is then converted to long-wave infrared radiation. Approx. 90% of this long-wave infrared radiation is reflected by the Low-Emissivity coating and retained inside the building. This results in lower heat loss through the window and thus, higher U-values. (Don’t use if you are trying to grow plants). The performance of the insulating glass in Southern climates may be further enhanced by utilizing bronze, grey or reflective -tint glass in addition to the Low - ”E” coating. This must be specified at the time you order. |

Argon Gas - The air space in our Low-E units can be filled with argon gas which will enhance the units energy efficiency about 13% by reducing the conduction of heat through the air space. (Not available with high-altitude tubes) (Not necessary for skylights in the top 2-3 rows of triangles). |
3% add-on |
Triple Pane - All 3 panes are 3/16" (or 1/4") tempered glass. 3/4" air spaces and 3 panes add 50% to the energy efficiency over double pane. Besides the energy efficient qualities of this unit, it has enhanced sound dampening characteristics |
38% add-on |
Bronze, Grey, or Green Integral Tinting - reduces heat gain and glare (see performance data.) Enhances detail similar to polarizing filter. Not a film. |
8% add-on |
Blue, Bluegreen, Evergreen, Azuria Integral Tint - reduces heat gain and glare (see performance data.) Enhances detail similar to polarizing filter. Not a film. |
15% add-on |
(Reflective Tint) (PPG Solarcool) Integral Tinting - substantially reduces heat gain and glare. Ideal for west facing or high south facing skylights. Not a surface applied film. Available in Solarcool Bronze, Solarcool Grey or Solarcool Green. |
25% add-on |
High-Altitude Skylights - for insulated glass installed or transported higher than 2500 feet above sea level, special breather tubes must be inserted into the air spaces to balance the outside air pressure and that between the glass panes. |

Other Options - these include; laminated safety glass (for coastal hurricane areas), patterned glass, high solar energy transmittance (90.4%) glass, bullet-resistant glass. Contact Natural Spaces for information and prices on these or other options. |
