Energy Efficient Glass Options

There are numerous options we offer for Energy Efficient Glass selection. The glass used for your window installation or window replacement is the single most important decision you’ll make in regards to energy efficient use. Our sales representative will work with you to gain the most energy efficient savings without exceeding your budget expectations during your glass window installation or replacement. This factor is key in getting tax credits and rebates from your local electric provider as well as reducing the energy bill. You’ve heard the terms relating to this – tint, low-e, insulated, double pane, argon gas. Let one of our experts talk to you about how it all works.

Energy Efficient Glass Definitions:

U-Factor:
Also known as the U-factor or coefficient of heat transmission, a measure of the rate of non-solar heat loss or gain through a material or assembly. U-values gauge how well a material allows heat to pass through. U-value ratings generally fall between 0.20 and 1.20. The lower the U-value, the greater a product's resistance to heat flow and the better its insulating value.

SHGC:
The fraction of external solar radiation that is admitted through a window or skylight, both directly transmitted, and absorbed and subsequently released inward. The solar heat gain coefficient (SHGC) has replaced the shading coefficient as the standard indicator of a window's shading ability. It is expressed as a number between 0 and 1. The lower a window's solar heat gain coefficient, the less solar heat it transmits, and the greater its shading ability. SHGC can be expressed in terms of the glass alone or can refer to the entire window assembly.

VT:
A measure of the amount of visible light that passes through the glazing material of a window, door, or skylight. Visible light transmittance, or simply visible transmittance (VT), is a fraction of the visible spectrum of sunlight (380 to 720 nanometers), weighted by the sensitivity of the human eye, which is transmitted through a window's, door's, or skylight's glazing. A product with a higher VT transmits more visible light. VT is expressed as a number between 0 and 1. The VT you need for a window, door, or skylight should be determined by your home's daylighting requirements and/or whether you need to reduce interior glare in a space.
