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

and condensation.



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

clearest view.




Full Aluminum Spacer

 With conventional

aluminum spacers,

condensation is a

fact of life.
