DaylightMax is Simonton's slim vinyl frame collection, designed to let in more light without giving up energy efficiency. The narrower frame puts more glass in the same opening than a conventional vinyl window, which suits view rooms and contemporary remodels.
The standard glass is a 3/4-inch double-strength insulating unit with ProSolar Low-E glass, argon and an Intercept spacer. Simonton lists DaylightMax sliding, single-hung, casement and picture windows (not every style in every region), and the DaylightMax sliding window carries the Good Housekeeping Seal. A black interior finish is offered in select Western states.
For a Twin Cities home, DaylightMax makes sense where the view matters; order the Northern-zone glass package, since a slimmer frame means the glass carries more of the insulating job.

Insulation and energy performance in Minnesota
DaylightMax trades frame width for glass area, so its winter performance rides on the glass package: 3/4-inch double-strength ProSolar Low-E argon on an Intercept spacer is standard. For Minnesota, order the Northern-zone ENERGY STAR package and the PLUS fourth-surface Low-E if it is offered on your style.
Glass packages
- Double-strength ProSolar® Low-E glass with argon in a 3/4-inch unit (standard)
- Intercept® spacer system
- Region-specific ENERGY STAR glass packages per Simonton's current catalog
Frame and sash
Reinforced slim-profile fusion-welded vinyl frame designed to hold a larger glass unit in the same opening while staying energy efficient.
Ratings
Simonton offers region-specific glass packages that meet ENERGY STAR guidelines; ask for the Northern-zone package and the NFRC label for the exact unit.
What the install adds
On install day we set the unit on a sill pan, tape the nailing fin or frame to the housewrap, fill the rough-opening gap with low-expansion foam, and finish the interior with backer rod and sealant so the air barrier is continuous. Exterior joints get backer rod and a quality sealant, so the rating on the label is what you feel in the room.
