Naco louvres help Savoy look the part

Naco, part of Ruskin Air Management, has helped make sure The Savoy look the part following its ground-breaking £100 million restoration.

Improvements to the hotel include a refit for all of its 268 bedrooms, nine floors, reception and extensive lift system. Naco’s louvres, which have been designed to fit in with the grandeur and style of the building, hide unsightly plant on the roofs of the 6th and 8th floor.


Supplied in Knock-Down (KD) form, built up on site, acoustic louvres and doors shield a plant room on the 6th floor; and on the 8th, lean back louvres do a similar job. Throughout the building, Naco restored existing louvres, matching new blades and brackets with their original counterparts to provide weather protection, including driven rain and storm winds, as well as improving the aesthetic appearance.

Due to the prestigious nature of the project, suppliers had to meet a challenging brief to ensure the hotel was brought up-to-date in a way that was appropriate and sympathetic to its 200 year-old heritage. All works had to be carried out while retaining original features.


The age of the building and these exacting requirements meant the project was not without its complications. Jeff Cooper, senior surveyor for the Chorus Group, which oversaw the restoration, explains: “As we stripped the building back unforeseen problems were revealed, particularly with the existing mechanical and electrical (M&E) systems. To this end, any suppliers we used had to react quickly to meet the continually changing requirements of the job.”

Its wide range of products, plus competitive pricing, meant that Naco was able to offer a range of potential solutions. “We were immediately impressed by Naco and have not been disappointed,” said Mr Cooper. “They have been positive and helpful throughout the entire project, consistently coming up with solutions to the issues that inevitably arose.

“Naco was able to react quickly to alterations to the brief; contributing their design and engineering expertise to ensure the louvres did their job, while also concealing equipment that would otherwise be visible and ruin the look of the building.”

Naco was involved at pre-tender stage and was required to produce a design solution from an early schematic design, which required a bespoke acoustic louvre system. The company’s 75 series of external metal louvres, manufactured from aluminium extrusions, were then selected and specifically adapted to meet the brief.

These fixed blade external louvres with 75mm blade spacing are suitable for a wide range of louvre assemblies where a ‘brick course’ line is required and are supplied in a continuous line standard construction. This was seen as the ideal approach for the roof area of the hotel and the ‘mill finish’ appearance blended in nicely.

The Naco louvres were produced in factory built panels before being coupled into the final assembly on site. This eased the installation process and avoided some of the access problems that can occur on a tight city centre site like the Savoy.

Naco supplied the louvres in 1.5m x 2.5m panels with rear mounted stiffener bars, which are fitted as standard to all louvres over 1.2m in width and connected to the blades with aluminium support clips. Stiffener bars do not interrupt the external continuous line appearance of the blades so meeting the aesthetic requirements of the project. The units also have reverse concealed mullions which project 45mm beyond the rear of the frame.

The Savoy is an extremely high-profile development, which required the Naco team to play its role as both designer and problem solver. The company has been supplying louvre solutions to the UK market since the early 60s and provides a full design, manufacture, supply and install service – including post-installation support. It also uses bespoke online sizing software to minimise potential design changes on site.

“Chorus rates the company highly and will definitely consider them for future work,” added Mr. Cooper.
