JELD-WEN

The JELD-WEN Premium Vinyl V-4500 is a vinyl replacement window with several Low-E glass packages. JELD-WEN publishes tested U-factor and SHGC data plus Energy Star qualification by zone. The company backs the line with a lifetime limited warranty.

Glass and Thermal Performance

The V-4500 offers Low-E glass packages including SunResist, SunStable, and SunFlow, with argon and HeatSave upgrades. JELD-WEN publishes a performance sheet with tested U-factor and SHGC numbers for each build.

JELD-WEN lists SunResist with argon at a U-factor of 0.27 and SHGC of 0.18. SunResist with HeatSave and argon reaches a U-factor of 0.24. These configurations lower energy costs by blocking heat gain.

Energy Star Qualification

JELD-WEN maps V-4500 glass builds to Energy Star climate zones on its performance sheet. Each row shows which zones a build qualifies for.

The sheet lists V-4500 builds that qualify for Energy Star across Northern, North-Central, South-Central, and Southern zones depending on the glass package. Buyers can match a build to their local climate zone.

Warranty

JELD-WEN backs its vinyl products with a limited warranty. The document sets separate terms for the frame, glass seal, and glass breakage.

JELD-WEN offers an Owner-Occupied Single-Family Residence Lifetime Warranty on its vinyl products. The warranty becomes ten years from the date of manufacture when the home is sold to a later owner. Sealed glass units carry a one year warranty against spontaneous breakage that includes free replacement glass and skilled labor.
