Spectre Window 35.5 in. x 59.5 in. Fiberglass Casement Window with Full Screen

Pultruded fiberglass moves with glass rather than against it: the frame expands at nearly the same rate as the insulated unit it carries, so seals stay tight through temperature swings that work vinyl and metal frames loose. The sash hinges at the side and drives outward with a crank operator, locking back against the slim 3 in. deep frame. Glazing is a double pane insulated unit with annealed panes; coatings and gas fill are confirmed during quote review. Frames come in white, black, or brown with a factory finish that never needs paint, and a full interior screen is included. A nailing fin installs the unit weathertight in new construction framing.

Specification Table

Included Equipment

• Assembled fiberglass casement window with insulated glass
• Full interior screen
• Crank operator and sash lock, factory fitted
• Nailing fin for new construction installation

Installation Notes

• Verify the rough opening is 0.5 in. wider and taller than the unit, square, with a level, supported sill before setting.
• Fiberglass frames are stiff; shim behind hinge and lock points rather than bowing the jambs to fit an out-of-square opening.
• Integrate the nailing fin with the weather barrier shingle fashion and flash the head.
• Operate the crank to full extension before fastening off to confirm the tall sash swings and locks without binding.
• Pre-drill fastener holes near frame corners to avoid stress cracking the pultrusion.

Warranty and Support

• Limited manufacturer-backed warranty program on frame, finish, and glass, confirmed during quote review.
• Quote packages include crank and lock adjustment guidance.

Frequently Asked Questions

Why fiberglass instead of vinyl?
Fiberglass is stiffer and more dimensionally stable than vinyl, holds dark factory finishes without heat distortion, and expands at nearly the glass rate so seals last longer. It is the step up for large sashes, dark colors, and harsh exposures.

Which hinge side do I order?
Hinge side is viewed from the exterior. Pick the side that swings the open sash away from patios and walkways, and pair left and right hinge units to crank sashes toward each other on wide walls.

What glass options are available?
Stocked units carry double pane insulated glass with annealed panes. Low-E coatings, gas fill, tempered panes, and privacy glass are confirmed during quote review.

Are more sizes or color pairings available?
The seventeen stocked size, color, and hinge pairings are listed on this page. Additional pairings within the platform are quoted on request.
