The Sunrise Series V4500 is MI's premium vinyl window for replacement applications, built on the Sunrise Windows and Doors design that MI acquired. MI describes it as sturdy and energy efficient: the double-hung's multi-chamber frame is filled with UltraCore polyurethane insulation as standard (an option on the sliders), narrow profiles give up to 27 percent more glass area, and HP Low-E coatings with argon improve energy performance. Optional SolarClean self-cleaning glass is offered.
Color choice is the widest in the MI vinyl line. Exteriors include White, Painter's White, Tan, Almond, Clay, Sandstone, Earthtone, Mystic Gray, Royal Brown, Antique Brown, Bronze, Cocoa, Cream, Forest Green, Vintage Linen and Black plus custom colors and Colonial Cherry, Hillside Oak and Natural Oak laminates. Interiors include White, Tan, Almond, Clay, Black and woodgrain laminates such as Colonial Cherry, English Walnut, Golden Oak, Provincial Oak, Norwegian Maple and Raw Pine. A matching V4500 sliding glass door is available.
For a Twin Cities homeowner who likes MI's dealer pricing but wants the best frame insulation and finish options, the V4500 is the step-up choice; order the Low-E argon package that meets the Northern ENERGY STAR zone.

Insulation and energy performance in Minnesota
The V4500 double-hung fills its frame chambers with UltraCore polyurethane, which most vinyl windows leave hollow (sliders offer it as an option), and pairs it with a warm-edge spacer and HP Low-E argon glass. For Minnesota, order the Low-E argon package MI lists for the Northern ENERGY STAR zone and ask the dealer for the NFRC label showing the U-factor for your configuration.
Glass packages
- HP Low-E coated insulated glass with argon fill
- Optional SolarClean™ self-cleaning glass and obscure glass
- Warm-edge spacer system to reduce edge-of-glass heat loss
- Triple-pane and upgraded Low-E options per MI's current product data sheet
Frame and sash
Multi-chamber vinyl frame and sash with UltraCore™ polyurethane insulation in the frame (standard on double-hung, optional on sliders); both double-hung sashes tilt in; awning has two low-profile locking handles.
Ratings
MI rates the V4500 double-hung ENERGY STAR and publishes U-factor and SHGC by glass package in each V4500 product data sheet; ask for the NFRC label for your configuration.
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.
