Spectre Window 25 in. x 35 in. Aluminum Clad Wood Casement Window with Low-E Insulated Glass

The sash hangs on side hinges and cranks outward with a folding handle in a champagne finish, locking back against the deep 4.56 in. wood jamb. A DP 50 structural rating and a sound transmission rated assembly are documented for the flagship size, a step above builder-grade vinyl. The glass is double pane annealed with argon fill and a high solar gain Low-E coating that admits winter solar heat while insulating against the cold, suited to heating-driven climates. Exteriors are clad in white, brown, or black aluminum; interior wood surfaces ship ready for site finish, with the factory finish state per colorway confirmed during quote review. An applied nailing fin installs the unit weathertight in new construction framing.

Specification Table

Included Equipment

• Assembled clad wood casement window with insulated glass
• Single point lock and folding crank handle, factory fitted
• Applied nailing fin for new construction installation

Installation Notes

• Verify the rough opening is 0.75 in. larger than the nominal size each way, square, with a level, supported sill before setting.
• Shim behind the hinge-side jamb at hinge points and the lock jamb at the keeper so the wood frame stays straight; wood jambs telegraph racking faster than vinyl.
• Integrate the applied nailing fin with the weather barrier shingle fashion and flash the head; seal the sill pan before setting.
• Protect unfinished interior wood from moisture during construction and seal or finish all interior surfaces promptly after installation.
• Operate the crank to full extension before fastening off to confirm the sash swings and locks without binding.

Warranty and Support

• Limited manufacturer-backed warranty program on frame, cladding, and glass, confirmed during quote review.
• Interior wood requires site finishing; finish requirements that affect coverage are confirmed during quote review.

Frequently Asked Questions

Why a high solar gain glass package?
The SHGC 0.51 coating admits winter solar heat while the Low-E surface still insulates, which lowers heating bills in northern and heating-driven climates. For cooling-driven climates, ask about a low gain package during quote review.

Is the interior finished?
Interior wood surfaces ship ready for site stain or paint; the factory finish state for each colorway is confirmed during quote review. The exterior aluminum cladding is fully finished and never needs paint.

Is a screen included?
No. An interior insect screen is available as an accessory and is quoted on request with your window sizes.

What does DP 50 mean?
Design pressure 50 means the assembly is rated for wind loads roughly double a DP 25 builder unit, documented for the flagship size. It suits exposed sites and jurisdictions with elevated wind requirements, confirmed against your local code during quote review.
