Kolbe Latitude

®

Series

The products and glazing options in the chart

shown below are NFRC listed or the listing

is applied for. The NFRC procedures use

Lawrence Berkeley Laboratory’s WINDOW

computer program and the THERM

computer program. The U total values are for

the entire window or door, including effects of

edge of glass spacer and frame. Performance divided lites

(PDL) and grilles-in-the-airspace glazing options generally

have the same U-values as one-lite units because the glass

spacer maintains a gap greater than 1/8" from the glass.

NOTE: All units shipped through high altitude areas utilize breather tubes which may affect overall energy performance.

Energy Performance Terminology

}

U-Factor

refers to a measure of heat transfer through the window or

door unit. A lower U-factor means less heat escapes during winter

weather, thus reducing heating costs in cold climates.

}

Solar Heat Gain Coefficient (SHGC)

is a measure of how much solar

energy is passing through the unit’s glass. The lower a window or door

unit’s SHGC, the less solar heat is transmitted into a room, thus allowing

for lower cooling bills in hot climates.

}

Visible Transmittance (VT)

is a measure of the portion of visible light

that passes through a window or door. The higher a window or door

unit’s VT Total, the more visible light is transmitted into a room. This value

is influenced by both the glass selection and by the ratio of glazing and

frame area.

Energy Performance Data

Standard LoE insulating glass has the low emissivity

coating on glass surface #2. This has the desirable

combination of visual clarity, good U-value, and low Solar

Heat Gain Coefficients (SHGC). Latitude Series units

have been tested at independent laboratories to AAMA/

WDMA (NWWDA) 101/I.S.2-97

specifications. The specification

requirements and selected

products are listed in the chart

provided.
