What makes ATIS different from a standard window frame?
ATIS is built around a minimal, slim-profile frame with L-Fit handles and near-invisible insect screens, so the design gets out of the way of the glass instead of competing with it.
Which products are available in the ATIS series?
Sliding, casement, awning, fixed, corner, French, tilt-and-slide, and slit windows, along with sliding and casement doors — all built on the same slim ATIS profile.
Does the slim frame compromise strength or weather sealing?
No — ATIS is still a fully pre-engineered system window, tested to the same global standards as the rest of the range, just with a more minimal visual footprint.
