How wide can a single roll shutter span?

A single-shutter assembly typically maxes out around 12 feet wide on standard slat gauge and 10 feet on heavy security/storm spec. Wider openings use multi-section assemblies with linked motors — operationally a single shutter, mechanically two or more.

Do multi-section shutters look like one shutter?

Visually they read as one. The slat curtains land at the same height, the head box runs the full width, and motorization is linked so they deploy in unison. There's a vertical seam where the sections meet — visible up close, invisible from the street.

Can roll shutters cover a 16-20 foot patio door?

Yes. Standard configuration is a two-section assembly with linked Somfy motors running on one wall switch. Bottom rails meet at the floor and seal the full width. Custom-fit to your exact opening so there are no gaps.

Do large-opening shutters need stronger tracks?

Yes. Multi-section assemblies use reinforced side tracks plus an intermediate post or rail support depending on the structural arrangement. We assess on the site visit and spec accordingly. The shutter still retracts fully into its head box.

Does a large opening change the install timeline?

Slightly. Multi-section assemblies take 1-2 days to install vs half a day for a single opening. Manufacturing lead time on custom assemblies runs 4-6 weeks. We schedule the install crew once the materials are confirmed in our shop.

What you get

Multi-section assembly, one operation.

A roll shutter on a 16-foot patio opening isn't one shutter — it's typically a two-section assembly with linked motors operating in unison. The bottom rails land together at the floor; the head box runs the full width; the wall switch controls both sections as one shutter. From operation, it's a single device. From engineering, it's a coordinated multi-section assembly.

Custom-fit means we measure your exact opening — including any out-of-square framing on older homes — and build the assembly to fit. No off-the-shelf compromises, no visible gaps when the shutter is deployed.

Reinforced side tracks handle the additional load on wider assemblies. Some configurations include an intermediate vertical post that disappears into the slat curtain when deployed and tucks against the structure when retracted.

What sets them apart

Four engineering details for large openings.

Linked-motor synchronization

Multi-section motors operate in unison from one switch. Both sections start at the same time, land at the same time, retract together.

Reinforced side tracks

Wider slat curtains carry more weight. Reinforced side tracks resist wind load and keep the shutter operating smoothly across decades.

Custom-fit assembly

We measure on-site and build to your exact opening. Out-of-square framing on older homes is handled in-shop, not papered over at install.

Continuous head box

Head box runs the full width of the opening rather than as separate units per section. Visually clean from the street, structurally rigid.

Where it fits

Three common large-opening installs.

Patio doors (12-20 ft)

Sliding patio doors and french-door openings in modern Ontario homes. Two-section assembly is the standard for this size class.

Multi-window facades

Living room or master bedroom front-facade with three to five large windows. One linked assembly across the whole bank rather than separate shutters per window.

Commercial storefront glass

Retail glass facades 16-30 feet wide. Two- or three-section assemblies with linked motors close the whole storefront from a single trigger.

What it costs

Wider runs cost more, ranges scale predictably.

Large-opening assemblies cost more than single-window installs in proportion to the linear coverage. A 16-foot patio door with a motorized two-section assembly typically lands in the $8,000-$15,000 range depending on slat gauge, motorization, and smart-home pairing. Commercial spans run higher. The cost scales with width, gauge, and the engineering required to spec the assembly properly.
