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. 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 row of triangles below the pentagon).

Triple Pane - All 3 panes are 3/16" (or 1/4") tempered glass. 3/4" air spaces and 3 panes adds over 50% to the energy efficiency over double pane. Besides the energy efficient qualities of this unit, it has enhanced sound dampening characteristics. The middle pane will have a small 1/4" diameter hole drilled through it in the corner near the edge.  This eliminates the unequal heat buildup in the air spaces.

Bronze, Grey, or Green Integral Tinting - reduces heat gain and glare (see performance data.) Enhances detail similar to polarizing filter. Not a film.

Blue, Arctic Blue, Bluegreen, Evergreen, Azuria, Atlantica, Cariba, Pacifica, Greylite, Supergrey - all of these are an Integral Tint - reduces heat gain and glare (see performance data.) Enhances detail similar to polarizing filter. Not a film.

(min. - some colors higher)

(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. Smaller skylights have to be increased from 3/16" thick glass to 1/4" glass, which requires an increase of 2%.

smaller sizes)

High-Altitude Skylights - for insulated glass installed or transported higher than 4000 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.  This eliminates the use of argon gas between the 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.
