All WASCO produced insulated glass (IG) units feature SuperSpacer®, a no-metal spacer, for warmer glass edge temperatures and reduced sound transmission. This advanced warm edge spacer helps keep the traditionally cold edges of the glass warmer. This area is where condensation typically begins, and SuperSpacer® is one reason WASCO's windows have a high condensation resistance (CR). A secondary seal of butyl rubber keeps the argon in over the long haul.
WASCO purchases IG units from Cardinal when the total area is over 15 ft2, the glass is tempered, or windows are shipped outside of WASCO's normal service area. For structural and/or warranty service reasons these units are supplied with Cardinal's XL Edge® spacer system.

WASCO's standard Solar Gain glazing is tailored to Wisconsin's climate, where heating loads dominate our energy bill. This glass has a high solar heat gain coefficient (SHGC), which allows in passive solar heat, reducing annual energy costs in our heating-dominated climate. This free renewable energy more than offsets the tiny increase in heat loss over low SHGC glazing, and yields better overall energy performance. This package is standard on all WASCO windows.
EnergyStar (TM) has calculated that an increase in 0.05 in SHGC is worth a decrease in U-Factor of 0.01 Btu/ft2°F in our northern climate. WASCO's engineer has independently verified this tradeoff, and LoE 180 glass does even better!
Cardinal LoE 180 reduces radiative heat transfer out of your house, while allowing free solar energy into the house, reducing heating bills.
Two layers of double strength glass, 3mm (1/8”) thick, along with SuperSpacer®, keep WASCO's windows extraordinarily quiet.
WASCO can optionally supply glazing that blocks out solar heat.
It features an outside layer of Cardinal LoE3 Glass and an inside layer of clear glass separated by an optimal 5/8” argon filled space. WASCO only uses double strength glass or greater. In Wisconsin, WASCO only recommends this choice if you have a large number of unshaded, west-facing windows
Cardinal LoE3 keeps inside glass temperatures warm in winter by reducing radiative heat transfer out of your house. It blocks solar energy in the summer, reducing air conditioning loads and increasing comfort.
Two layers of double strength glass, 3mm (1/8”) thick, along with SuperSpacer®, keep WASCO's windows extraordinarily quiet.
A triple pane unit with an overall width of 1.375", this package combines a very low U-Factor with a relatively high SHGC, yielding the ultimate choice for Wisconsin's climate. It is optional on WASCO Tilt & Turn Windows and WASCO Casement Windows. This is the perfect glass for south-facing windows. It is not recommended for large, unshaded west-facing windows where summer heat has been a problem.
Glass: Cardinal LoE 180 holds interior heat in while allowing solar energy to help heat your house in winter. Ideal for sustainable design. All three panes are double-strength, 3mm (1/8") thick or greater – no flimsy single strength panes or plastic films.
Triple pane glass yields warm interior glass temperatures in winter and blocks outside noise.
A triple pane unit with an overall width of 1 3/8", this package was developed to maximize comfort by maintaining inner glass temperatures as close to room temperature as possible in all seasons. It is optional on WASCO Tilt & Turn Windows and Casement Windows and recommended for unshaded west-facing windows when triple pane is desired.
This is a true and highly robust triple-pane: All three panes are double-strength glass – no flimsy single strength panes or plastic films. This keeps out sound while two 1/2” argon-filled spaces keep in heat.
Glass: An outer layer of Cardinal LoE3, a layer of Cardinal LoE180 on the inside with a clear light in the center keep heat inside your house and reduce air conditioning loads. All layers are double-strength, 3mm (1/8”) thick.and seperated by SuperSpacer®.
The following data was generated using LBNL Window Research Version 6.0. U-Factor and winter interior glass temperatures were calculated for NFRC 100-2004 Winter Conditions (approximately 0°F outside); SHGC's were calculated for NFRC 100-2004 Summer Conditions (approximately 90°F). These figures are solely for comparing glazing packages. Whole window U-Factors should be used for comparing windows.
