From metalworking machinery to lightweight aluminium slats.

Hunter Douglas dates its story to 1919. On the timeline it publishes for its Canadian customers, under the heading “100 Years of Innovation”, the company says that Henry Sonnenberg founded a machine-tool manufacturer in Germany that year, and it treats that business as its beginning. The window covering came later. The same timeline says that in 1946 Sonnenberg partnered with the American entrepreneur and inventor Joe Hunter to design lightweight aluminium blinds.

That partnership explains both halves of the name. The Hunter of Hunter Douglas is Joe Hunter, and the business he and Sonnenberg built joined machine know-how to a household product. The company’s current group website puts the year 1946 at the centre of its window-coverings story, and the slatted aluminium blind is the product with which the brand entered the home.

The family connection to the founder has run through the company’s whole history. In a joint press release issued in Rotterdam and New York on 30 December 2021, Ralph Sonnenberg, then the controlling shareholder, said that Hunter Douglas “was founded by my Father over 100 years ago”. The same release referred to the leadership of the Sonnenberg family over three generations, and named David Sonnenberg as the group’s co-president and co-chief executive at the time.

The corporate form has changed along the way. English Wikipedia says the present parent, Hunter Douglas N.V., was formed in the Netherlands Antilles in 1971 through a restructuring of the earlier Canadian company, Hunter Douglas Ltd, and that the group’s headquarters are in Rotterdam, with a management office in Lucerne, Switzerland. The 2021 press release was issued on Rotterdam letterhead. The company’s Canadian timeline says that between 1960 and 1980 it expanded its operations in Europe, Australia and Latin America.

Honeycombs, sheers and vanes, then a new owner.

From the mid-1980s the brand became known less for slats than for fabric. The company’s timeline lists Duette honeycomb shades in 1985, which it describes as an energy-efficient honeycomb design. Silhouette window shadings followed in 1991; the company says they use S-shaped vanes suspended between two sheer fabrics to diffuse sunlight and give privacy. Luminette privacy sheers arrived in 1997, with vertical vanes that rotate on the back of a sheer, and Pirouette shadings, with contoured fabric vanes, in 2007.

The same list records a parallel line of operating systems. The company says its PowerRise system of 1996 was a battery-powered remote-control system, that LiteRise in 2001 was a manual system without lift cords, and that PowerView motorization in 2015 could be controlled from a smartphone, a tablet or a Pebble remote. Later entries include Sonnette cellular roller shades in 2017 and the Duette LightLock in 2018.

Hunter Douglas uses more than one name for these products. On its group website in May 2022, as preserved by the Internet Archive, the company presented Hunter Douglas as its brand for custom-made window treatments in North America and Luxaflex as its brand name in Europe, carrying proprietary names such as Silhouette, Duette and Facette. The same page listed an architectural business, Hunter Douglas Architectural, making ceilings, sun-control systems and façades, alongside 3form, NBK terracotta and Mermet sun-screen fabrics. It described the group as a decentralised federation of companies and gave its guiding principle as “Business is people”.

The group has also bought other window-covering names. In March 2016 Consumer Goods Technology reported that Hunter Douglas had agreed to acquire the Levolor and Kirsch brands from Newell Rubbermaid; English Wikipedia says the sale of Levolor completed in July 2016. Wikipedia also records later purchases in the United Kingdom, including Hillarys in 2017, and the acquisition of the American online retailer Select Blinds in October 2023.

Ownership changed in 2022. Under the December 2021 agreement, Ralph Sonnenberg agreed to transfer a controlling interest in the company to 3G Capital, an investment firm, with the Sonnenberg family keeping a minority interest; the release said David Sonnenberg would become executive chairman after closing. A client note from the law firm Paul, Weiss dated 25 February 2022 announced that 3G Capital had completed the acquisition of the controlling interest. 3G Capital has controlled Hunter Douglas since February 2022.

Design and documentation.

The brands in this group all make or sell window coverings: blinds, shades, shutters and the fabrics and mechanisms behind them. Window-covering brands sit at many different points in the trade, from family workshops that cut each blind to order to names that now belong to much larger home-furnishings groups, and the same name can reach a buyer through a showroom, a decorator, a catalogue or a website.

A window-covering brand’s identity is usually carried less by one product than by a name, a swatch book, a showroom and the promise of a made-to-measure fit, because the company behind the name may have changed hands, moved its manufacturing or grown far beyond the place where it started. That makes the questions behind each name worth asking plainly: who started it, who owns it now, and where its blinds and shades are actually made.

Each guide separates what independent sources record from what the company says about itself — its founding story, its owners over time, where its products are made and how its identity has changed — and marks plainly what rests only on the company’s own word.

A brand told through light, fabric and named systems.

Hunter Douglas presents itself through its products as much as through its name. Its own timeline is a list of trademarks, each with a year: Duette, Silhouette, Luminette and Pirouette among the shades, PowerRise, LiteRise and PowerView among the operating systems. The company’s descriptions of them — a honeycomb, S-shaped vanes between sheers, vanes rotating on a sheer — give the brand a vocabulary of soft geometry.

The architecture of the group shapes how the brand appears in different places. A shopper in North America meets the Hunter Douglas name; according to the company’s 2022 group website, the same proprietary shades are sold in Europe under Luxaflex. Behind both sits a group that described itself as a federation of companies and that has added further names, from Levolor in American home centres to online retailers in the United Kingdom and the United States. The 3G Capital agreement of December 2021 also spoke of Hunter Douglas’s network of dealers and fabricators, the specialist channel through which custom coverings reach a home.

The founding story gives the brand its longest thread. A machine-tool business founded by Henry Sonnenberg in 1919, a 1946 partnership with Joe Hunter on lightweight aluminium blinds, and family leadership that the 2021 release counted across three generations: these are the facts the company itself returns to. Since February 2022 the controlling owner has been 3G Capital, with the family retaining a stake.

For a design guide, Hunter Douglas shows how a family of product names, each tied to a specific way of filtering daylight, can carry a brand that sells through dealers under more than one masthead. Compare the mass-market blind brand it owns in our Levolor brand guidelines and a motorised shade system from a lighting-control company in our Lutron Serena brand guidelines. For this guide we use slate, linen, window blue and sheer white with a sans, an unofficial interpretation; no product or logo is reproduced.
