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 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.
Installation should be completed by a licensed contractor.

Frequently Asked Questions

What does thermally broken mean?
A reinforced polyamide strip separates the interior and exterior aluminum faces of every frame and sash profile, cutting conducted heat flow and interior condensation compared with plain aluminum. The catalog positions this series for heat and noise insulation.

What glass comes in it?
A two pane insulated glass unit sits in the 25 mm glazing pocket. The exact glass 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.

How does this compare with the 70 Series?
Both are thermally broken. The 70 Series carries a deeper 2.76 in (70 mm) frame with 3.07 in (78 mm) sashes for larger openings and stronger insulation, while the 55 Series is the value thermal tier for standard openings.
