Doors That Disappear Into the View 

Superior efficiency. Effortless operation. Built to last.

Open your patio door however the space calls for it. The lift-and-slide systems glide open on a sealed track for a wide, unobstructed view, while fold systems stack open like an accordion for a true wall-to-outdoors transition. No dragging, no sticking, no gap for weather to sneak through when it's closed. It's the difference between a door that feels like a chore and one that feels like it belongs in the room.

This is what Use Better Windows looks like

Available in uPVC and aluminum, so you can match both the mechanism and the material to the opening - even letting the door disappear.


uPVC Doors
Built on the same multi-chamber frame technology as our windows, our uPVC patio doors and sliders give you a large-format opening without giving up thermal performance.

Why builders and architects choose it

  • ~0.17 U-value holds its performance even at large door sizes

  • Multi-point locking across the full height of the panel

  • Smooth, low-effort operation even on large slide widths

  • Weather-sealed threshold designed for real winters

  • Low-maintenance frame; no repainting, no rot

Aluminum Doors
When the opening gets big: multi-panel slides, pocketing doors, or folding walls; aluminum is what makes it structurally possible without a chunky frame in the way.

Why builders and architects choose it

  • Slimmest available sightlines for maximum glass area

  • Slide and fold configurations, including bi-fold walls that stack down to a fraction of the opening width

  • Sash sizes and weights for oversized walls of glass, beyond what uPVC can structurally carry

  • Built for exposed, high-use outdoor-facing walls

Why the Numbers Matter

A patio door has more glass and more moving parts than a standard window, which makes thermal performance harder to hold onto and that's exactly where most budget sliding doors fall apart. Ours are engineered to maintain 0.15 U-value or better, even at large panel sizes, so opening up your wall to the outdoors doesn't mean opening up a gap in your home's performance.

How We Work With You

1 - We review your plans
Send us your drawings early. We’ll work with your builder and architect to identify where performance, sizing, or hardware choices matter most.

2 - We provide a detailed estimate
Frame material, glazing, color, hardware - every unit is built to specs. Estimates include all product and shipping costs.

3 - We handle logistics
Custom European manufacturing means lead times matter. Typical time is 8-10 weeks from confirmed order to on site delivery.

4 - We support installation
With a background in building, we know what crews need to get this right the first time, and we're on call for questions during the install. 

See them in person. Schedule a showroom visit or ask us to bring samples to your next job walk.
