Name: Door Axis 126 Series 3-Panel Stacking Sliding Patio Door with Integrated Screen, Thermal Break
Brand: Door Axis
SKU: DA-DR-PAT-SLIDE126-3T-SC-14-SB

The Door Axis 126 Series is a three track, thermal break sliding patio door whose three panels stack for a wide clear opening while an integrated screen leaf keeps insects out with the glass open. It serves patios, lake and garden rooms, and climate driven projects that want ventilation without giving up a screened opening.

A 4.96 in (126 mm) three track frame with a polyamide thermal break carries three 2.83 in (72 mm) glass panels that slide and stack behind one another, opening up to two thirds of the span. The integrated screen leaf runs on its own track, inside or outside per the order, so airflow and insect protection work together. Panels run 27.5 to 47.2 in wide (700 to 1200 mm) at heights from 78.7 to 118.1 in (2000 to 3000 mm) with insulated double glazing and a 1.4 mm or 1.6 mm profile wall. Each system is fabricated to the opening size in one of eight standard finishes.

Installation Notes

Verify the rough opening, header deflection, and sill support before release; three track sills need continuous, level bearing.
Install a sill pan and integrate flashing and waterproofing with the wall assembly on exterior openings.
Set the frame plumb, level, and square, then adjust rollers so glass and screen leaves glide without binding.
Installation should be completed by a licensed contractor.
Confirm screen position (interior or exterior track) and stacking direction during quote review.

Warranty and Support

Warranty coverage is confirmed during quote review before release.
Quote packages include hardware adjustment guidance and finish care notes.

Frequently Asked Questions

How does the integrated screen work?
A dedicated screen leaf rides its own track, inside or outside the glass panels per the order, so you can slide glass open and keep the screen closed for ventilation without insects.

How much of the opening clears?
The three glass panels stack behind one another, opening roughly two thirds of the span. Exact clear opening depends on your panel sizes and is confirmed during quote review.

How does the thermal break help?
A polyamide barrier separates interior and exterior aluminum, reducing conducted heat and cold and helping with condensation control. Project specific performance targets are reviewed during quote review.

Which finishes are available?
Eight standard finishes: Sand Black, Sand Gray, Snow Gray, Pure White, Fluorocarbon Champagne, Red Cherry, Golden Oak, and Black Walnut, applied as PVDF fluorocarbon or woodgrain film over extruded aluminum.
