Bi-fold and folding doors turn an entire wall into an opening — a stack of glass panels concertinas back to one or both sides, so a kitchen, sunroom or living room can open almost completely onto a patio or yard. ArcView builds bi-fold and folding door systems on thermally-broken aluminum frames and hardware engineered for smooth, reliable operation over a wide multi-panel span, for homeowners and projects across Canada.
Quick answer
ArcView bi-fold (folding) doors are thermally-broken aluminum multi-panel systems that fold and stack to open a wide wall of glass, giving a wider fully-open opening than a sliding door across the same wall width.
- Multi-panel folding system — panels stack to one or both sides for a wide, fully-open opening
- Aluminum track and hardware engineered for smooth operation across the full panel run
- Thermally broken frames for Canadian climate performance
How bi-fold doors differ from sliding patio doors
A sliding door always leaves one panel's width of the opening covered by the stacked panels; a bi-fold door folds each panel back against itself, so a much larger share of the total opening width can be left completely clear when fully open. If a wide, unobstructed wall-to-outdoors opening is the goal — more than an oversized slider — bi-fold is usually the better fit. If a slimmer sightline with fewer moving panels and a lower cost is the priority, our sliding and patio doors may be the better match; talk to your ArcView representative about which suits your opening.
Track and hardware
Because a folding door run carries several panels on a single track, the quality of the track and hardware determines how smoothly the door operates over years of use. ArcView's aluminum folding systems are engineered for reliable multi-panel operation, and the aluminum frame's strength-to-weight ratio helps keep individual panels slim without sacrificing structural rigidity across the full run.
Configurations
Bi-fold configurations range from a compact 2-3 panel opening up to wide multi-panel runs, folding to one side or splitting to fold to both sides of a wide opening. Panel count, stacking direction and opening width should be confirmed with your ArcView representative based on your wall opening and layout.
| Bi-fold vs sliding | Bi-fold | Sliding patio door |
|---|---|---|
| Clear opening when fully open | Most of the opening — panels fold against themselves | Always one panel's width stays covered |
| Panels in the run | Several, on a shared track | Typically two, up to multi-panel |
| Sightline when closed | More frame lines across the glass | Fewer, slimmer sightlines |
| Relative cost | Higher — more panels and hardware | Lower |
| Choose it when | A wide, unobstructed wall-to-outdoors opening is the goal | A slimmer sightline and lower cost matter more |
Thermal performance and weatherproofing
Thermally-broken aluminum framing limits heat transfer through the frame, and quality weatherstripping across a multi-panel folding system is essential to keeping the assembly weathertight when closed. As with any ArcView product, confirm the certified U-value and ER rating on the specific unit and glazing package you're quoted for your project.

Frequently asked questions
What is a bi-fold door? A bi-fold (folding) door is a multi-panel glass door where each panel hinges to the next and the whole stack folds and slides back to one or both sides of the opening, leaving most or all of the wall width clear when fully open.
Bi-fold door vs sliding patio door — which should I choose? Bi-fold doors open a wider share of the total wall width because panels fold clear rather than stacking in front of each other; sliding doors have fewer moving parts, a slimmer sightline when closed, and are often lower cost. See our sliding and patio doors page and talk to your ArcView representative about which fits your opening.
How many panels can a bi-fold door have? Bi-fold configurations range from a compact few-panel opening to wide multi-panel runs folding to one or both sides. Confirm panel count and maximum run width for your specific opening with your ArcView representative.
Are bi-fold doors weathertight when closed? Yes — a properly specified aluminum bi-fold system with quality weatherstripping across each panel junction is designed to be weathertight when closed. As with any door, confirm the certified performance rating on your specific unit.
Do bi-fold doors work in a Canadian climate? Yes — ArcView's bi-fold doors use thermally-broken aluminum frames engineered for Canadian climate performance, the same construction principle used across our window and door lines.
Where is ArcView's bi-fold door line available? ArcView serves Toronto and Ontario, Winnipeg and Manitoba, plus Vancouver, British Columbia and Calgary, Alberta as part of our Canadian operations. Request a quote to get started.
