Heat Sheild Glass:
Compare Florian's high performance glazing with any other.
Follow the simple guidelines below when choosing the right
glazing to "solar tune" your solarium, conservatory, sunroom
kit, or custom.
Women - In an Insulated Glass Room
Man - Florian's Glazing Greater Comfort "no sweat"
Problems:
* Overheating - relative heat gain
* Glare - % UV Light transmittance
* UV Fading damage - % UV Light transmittance
The Solution:
Overheating problems are solved by using a combination of very low relative heat gain glass. We recommend a rating of 45 or lower for roofs, and 90 or lower for walls.
Glare problem solved by filtering visible light transmittance to a comfortable level of 69 or
UV Fading damage is tremendously reduced by using a UV Light transmittance of 10 blocking 90% of UV rays. These problems are common when ordinary insulated glass; clear, bronze or regular LOW-E's; is used by our competition in these exposers.

Women-Our Competitions Glazing Man-Florian's Glazing Saves Dollars, Makes Sense
Problems:
* Drafts, cold feeling - winter inside glass temperature
* Condensation forms on glass- inside dew point
* Heat escapes with little resistance - winter R-Value
Solution:
* Drafts eliminated by using a winter inside glass temperature of 57 degrees or higher
* High resistance to condensation with an inside dew point of -2 or lower
* higher insulation R-VALUE keeps heat in
Choose an R-VALUE or higher
Common with the competition's glass, these problems cause drafts, condensation and large amounts of heat loss.
Florian offers several options for glazing to meet any budget and performance requirements.
GLOSSARY OF TERMS FOR GLAZING CHART
A - "Glazing code" - Refers to Florian's recommendation for selecting glass (R) roof, (W) wall.
B - "Glazing description" - A description of the components used to obtain the glazing unit being described.
C - "Upcharge over clear" Insulated - Multiply the number in this column by the total square footage of option and add to the base price of a standard unit with clear glass.
D - "Unit Availability" - Glass is available as a standard in the units specified in this column.G- Geneva greenhouse kit, S- Sierra sun room, sun room kits and solarium, W- Woodhaven solarium & sun room.
E - "Shading co-efficient" - Multiplier for the amount of solar gain entering through the glass. For example: a piece of with a shading co-efficient of .85 would let in 85% if the solar gain that would travel through a 1/8" piece of clear glass.
F - "Relative heat gain" - The measurable amount of energy which penetrates the glass is expressed in terms of BTU's of heat gain per hour per square foot of glass area.
G - "% Visible light transmittance" - The percentage of light in the visible spectrum, that is directly transmitted through the glass.
H - "% UV light transmittance" - Percentage of ultra-violet radiation transmitted through the glass.
I - "Inside the glass temp" - The temperature of the inside surface of the glass in degrees F when the following ashrae conditions exist. Outside temperature of 0 degrees F with a 15mph wind, and inside temperature of 70 degrees F.
J - "Inside dew point" - The outside temperature in degrees F that will cause condensation on the inside surface of the glass. This number assumes an inside relative humidity of 60% and a temperature of 70 degrees F.
K - "Winter U value" - The total heat transfer co-efficient which is the measure of heat loss through the glass due to a difference between indoor and outdoor air temperatures. The lower the U value, the better the insulating properties of the (BTU/HR/SQFT/F)
L - "Winter R value" - The resistance to heat loss through the glass. The higher the R value, The better the insulating properties. (R=1/U).
