Installation Notes

Verify the rough opening is square, level, and plumb and about 0.75 in larger than the unit each way before release.
Custom sizes and window wall layouts are fabricated to the opening within the factory range; exact dimensions are confirmed during quote review.
On exterior walls integrate head flashing and a sealed sill joint per local code; keep weep paths clear.
Shim at hinge points and lock keeps so sashes compress evenly against the gaskets; check multi point engagement.
Installation should be completed by a licensed contractor.

Quote packages include hardware adjustment guidance and finish care notes.

Frequently Asked Questions

Why choose the 70 Series over the 55 Series?
The 70 Series carries a deeper thermally broken frame and heavier 3.07 in (78 mm) sashes, which supports larger sashes, window wall layouts, and stronger heat and sound insulation. The 55 Series is the value thermal tier for standard openings.

Can it be built as a window wall?
Yes. The factory shows outward opening multi sash window walls with fixed top lights on this series. Layouts are engineered per opening during quote review.

What glass comes in it?
A two pane insulated glass unit sits in the 25 mm glazing pocket. The exact makeup, including any coating or obscure option, is confirmed during quote review.

Are the listed sizes the only sizes?
No. The three nominal sizes anchor quoting. Every window is made to order with sashes 19.7 to 33.5 in wide and 47.2 to 70.9 in high, sized to your opening during quote review.
