Crestron horizontal sheer shades are fabric vanes suspended between two layers of sheer fabric, and Crestron Home 4.12, announced on 22 September 2026, added support for new tilt limit firmware for them. In a London home they solve a familiar problem, keeping the street or the flats opposite from seeing in while the room keeps its daylight, and Residential Systems reports a refreshed range of Crestron roller shade fabrics expected in November 2026.
What changed in Crestron Home 4.12
Crestron's post on Crestron Home 4.12, published on 22 September 2026, lists support for Horizontal Sheer Tilt Limit firmware among the release's other features. It says the controls for its horizontal sheer shades "now include firmware that allows for the perfect setting, every time", and that the firmware is supported from 4.12. CE Pro reported the firmware support three days later.
That is as much detail as Crestron has given. In what we have read, it has not described how the limit is set or what range it covers, so we will confirm exactly what it changes on your shades when we update a system. What we can explain is why the angle of the vanes matters so much.
How Crestron horizontal sheer shades work
On Crestron's product page, the shade is described as horizontal fabric vanes floating between two layers of sheer, knitted fabric. Raised, it leaves the window clear. Lowered, the vanes tilt to various angles to control how much daylight comes in, while the sheer layers keep people outside from seeing in clearly.
- Vanes. The 3 inch vanes, introduced in November 2025, give what Crestron calls an approximately 1.5 inch view when tilted open.
- Fabrics. Three collections, Telluride, Vail and Keystone, each in several colours and in two opacities, translucent and light dimming.
- Protection. Crestron says the two sheer layers filter UV, which helps protect furniture, floors and artwork, and that closed vanes give more protection than open ones.
- Size. Up to 303.5 cm wide and 244 cm high depending on the fabric, with a minimum width of 45 cm.
- Motor. Crestron's Digital QMT motor, controlled over wired Cresnet or infiNET EX wireless and powered at 24 volts DC from a local or central power supply. A manual version with a bead chain is also made.
Leah Martinez, Crestron's product manager of control and environmental solutions, explained the bigger vane when it launched: "A larger vane gives a homeowner a more expansive connection to the outdoors while still softening and diffusing light." She said the aim was to improve the view for owners of homes with "striking landscapes or cityscapes".
Why they suit London windows
- Street facing bays. In a Victorian or Edwardian terrace the front reception room often sits a few metres from the pavement. Lowered sheers keep the room private in the day without the gloom of a closed blind.
- Flats facing flats. In a mansion block or a new apartment building, a living room can look straight into the windows opposite. The sheer layers blur the view in, and the vanes decide how much daylight you keep.
- Views worth keeping. Where an apartment looks over a park, the river or the skyline, the larger vane is meant for exactly that.
- Screens and art. Softer daylight means less glare on a television or a home office screen, and Crestron's UV claim matters if you own paintings or hardwood floors that would fade.
At night, with the lights on inside, sheer fabric hides less, so in bedrooms and rooms on the street we often pair horizontal sheers with a blackout roller shade or curtains.
The new Crestron roller shade fabrics
The second update is for roller shades, the single piece of fabric that rolls up and down. Residential Systems reported on 10 September 2026 that a refreshed Roller Shade Fabric Collection brings eight new fabric collections in Designer and Heritage families, covering sheer, light filtering and blackout options, with a redesigned sample bag holding 222 fabric samples, 58 of them new. It listed the collection as expected in November 2026. Crestron has not published prices or availability for this country.
If you are choosing fabrics this autumn, the timing matters. For a project being measured in November or later, ask us whether the new samples have reached this country before you choose. For shades being made now, the choice is from the current Heritage and Designer ranges.
Shades as part of a Crestron home
Crestron says its motorised horizontal sheers can be controlled from keypads, touch screens, handheld remotes and phones, with lighting and shading scenes recalled at the press of a button or to a schedule. In practice that means one Evening button can dim the lights and close the sheers together, and a morning schedule can open the bedroom shades at the time you choose. Crestron's new 15 inch TSW-1580 touch screen is another way to run them, and our lighting control team in London designs the scenes so that lights and shades work as one.
What a Crestron system needs
- Crestron Home 4.12 or later for the tilt limit firmware, on a processor that runs it. Crestron's manual lists the CP4-R (Version 2), MC4-R (Version 2) and DIN-AP4-R for 4.11 onwards.
- A service visit. The firmware is for the shades and 4.12 is the release that supports it, so your Crestron installer in London updates the system and checks whether each shade can take the firmware. Our Configure Pro post explains how Crestron Home systems are now set up.
- For new shades, power and control at each window. Each horizontal sheer motor needs 24 volt DC power and either a Cresnet cable or a wireless infiNET EX link, so the cable route to the window head is agreed before decorating.
For what a visit costs, see our smart home cost guide, and for the wider range of blinds and curtains we fit, our motorised blinds page for London.
How 1Install can help
As a Crestron installer we specify and fit Crestron shades alongside the lighting and the rest of the system, and we can bring an existing Crestron Home system on a supported processor up to 4.12 and check whether its horizontal sheers can take the new firmware. Our process sets out the stages from survey to handover, and 1Install Care keeps the shades, the lighting and the processor supported afterwards.
Questions we are often asked
What does the tilt limit firmware actually do?
Crestron describes it only as firmware that "allows for the perfect setting, every time", supported with Crestron Home 4.12. We will confirm the detail on your shades when we update the system.
Do horizontal sheers give privacy at night?
Crestron says the sheer layers obscure the view into the home. With the lights on inside after dark the effect is weaker, so for bedrooms and street facing rooms we often add a blackout layer alongside them.
Will horizontal sheers work in a bay window?
Yes. Each window in the bay gets its own shade, and Crestron's minimum width is 45 cm, so narrow side windows need measuring first.
How large can a single shade be?
Crestron lists widths up to 303.5 cm and heights up to 244 cm, depending on the fabric, so a very wide opening is split into more than one shade.
Can my existing Crestron horizontal sheers get the update?
The firmware is for Crestron's horizontal sheers and is supported from Crestron Home 4.12, so the first step is checking your processor and shades, which we do in a service visit.
