Large viewing area window that has a sliding center sash and the left and right glass is fixed in place.
Also a traditional style, popular double hung windows open by raising the bottom sash or lowering the top sash of the window.
Large viewing area window that has sliding left and right sashes and the center glass is fixed in place.

E-Z Fill® Foam is inside every frame for the
best performance and value.
Vinyl frame windows with E-Z Fill® foam are the most energy-efficient choice – better than aluminum, wood or hollow vinyl. That makes them a good value now and in the future.
Simply adding polyurethane foam to vinyl window frames improves
overall thermal efficiency 3 to 8 percent. That means lower energy costs for you and fewer greenhouse gases to damage the environment.
E-Z Fill® works like the foam used to insulate a cooler, thermos or refrigerator – helping to retain internal temperatures. In addition, E-Z Fill® foam helps to prevent condensation that can lead to unsightly mold and damaged window sills.
Vinyl frame windows with E-Z Fill® foam help retain heat and save on energy costs.
These thermographic images show resistance to heat loss in an air-filled window frame, right, and a frame filled with E-Z Fill®, left. The dark area indicates cooler temperatures, more prominent in the air-filled frame on the right.
D&W window frames are made with Sunshield®, an
advanced material formulated to withstand the harsh
effects of weather and ultraviolet light.
The environmentally safe Sunshield compound exceeds all required material standards for strength.
• Third‐party verification to guarantee Sunshield performs well in any climate
• High‐grade compounding systems provide consistency in formulations for superior reliability
• Flame spread is slow and products are self‐extinguishing when fire source is removed
• Products made with Sunshield are efficient to produce and 100% recyclable
Solar Control Low-E Glass for lower energy costs.
Cooler In Summer
The transmitted through Solar Control Low-E Glass is almost 51%
less than that transmitted by standard clear insulating glass.
• Lower SHGC numbers mean less summer heat
• Keeps interiors cooler
• Helps reduce cooling energy costs
Warmer In Winter
The winter nighttime U-Value (insulating value) of Solar Control Low-E
Glass is almost 50% better than standard clear insulating glass.
• Lower U-values mean higher performance
• Reduces furnace heat loss
• Helps reduce heating energy costs
Solar Control Low-E Glass
Standard Clear Insulating Glass
Super Spacer® – the most advanced insulated glass
system. Super Spacer® is up to 950 time less
conductive than standard aluminum spacer bar.
The No-Metal Super Spacer® Advantages
NO-Metal Super Spacer blocks the heat escape
path and protects the glass edge from moisture
A Full Aluminum Spacer
Standard aluminum spacer bar can conduct heat
and cold – causing condensation at the edge of the
glass. Convection currents further concentrate
cold air along the bottom edge of glass making
that area the most vulnerable.
Only a 100% foam spacer design helps keep moisture off the glass though warm edge technology.
No-Metal Super Spacer® Patented all-foam design dramatically reduces window condensation, delivering the
Full Aluminum Spacer
condensation is a
fact of life.
