Low E Double Glazing Glass Types & Performance
Stake Glass supplies the following two Saint-Gobain Low E glass types:
PLANITHERM ULTRA N low-E glass offers advanced thermal insulation properties for the most demanding of glass specifications, where neutrality and excellent performance are paramount. A double glazed window using PLANITHERM ULTRA N low-e glass will give you a U Value of 1.1, when it is combined with a 14mm thermal spacer and argon gas. Click here for more information.
COOL-LITE is used for applications requiring high solar protection and high light transmittance. A double glazed window using COOL-LITE SKN 176 II low-e glass will give you a U-value of 1.0, when it is combined with a 16mm thermal spacer and argon gas. Click here for more information.
Get To Know Your Glass
Here is a list of explanations of common glass terminology so you are not left in the dark.
U Value
This measures the difference between the indoor and outdoor temperatures, or how much heat passes through your glass. A lower U-value means lower heat transfer and better insulation of your home.
Solar Factor (g)
The Solar Factor or g value of the glass tells us how well the glass transmits heat from the sun. It measures how much solar heat is being allowed in through the window. The lower the figure, the less solar heat transferring from outside to in, whereas a higher figure will allow more in.
Shading Co-Efficient
Shading co-efficient is a measure of the effective solar rejection performance of a given glass type. A lower shading co-efficient indicates higher restriction of the transfer of solar heat.
Low Emissivity (Low E) Glass
A Low E coating reduces the amount of heat transfer through a pane of glass. Low E coatings can reflect radiant heat - either from outside or inside, therefore reducing the heating and cooling costs of your home.
Argon
Argon gas is a naturally occurring, non-harmful gas. When Argon gas is inserted between the panes of glass it increases the insulating performance of your double glazing.
