In a “remarkable synthesis of past and present”, Kingspan Insulated Panels have been used in a £220m retrofit of London’s glamorous Savoy Hotel, which has resulted in the building being returned to its Edwardian and art deco splendour while at the same time embracing the very latest insulation technology.
MWC Contracts (Roofing) Ltd used the very latest in pre-engineered, insulated panel technology from Kingspan Insulated Panels to create new roofing for the Thames Room and the Beaufort Bar in the foyer area of the hotel.
240m2 of Kingspan KS1000 Lo-Pitch (LP), a high specification low pitched roof system and approximately 150m2 of KS1000 RW, a through fixed trapezoidal profiled system, both in Goosewing Grey Kingspan XL Forte™ were installed at the hotel.
As with other Kingspan panels, KS1000 LP and RW provide exceptional thermal performance, with an airtightness of 5m3/hr/m2 certainty over the lifetime of the insulation. The panels are single component, single-fix systems, which can accelerate build speed and achieve labour cost savings, an important factor, as Nick Smith from MWC Roofing explained. He said:
“Access to the working area at The Savoy was limited due to the lack of space on site, therefore no use of hoisting facilities could be made. The Beaufort Bar especially presented extreme difficulty but we’d used Kingspan panels many times before and we knew they are easy to install because the system is an "all in one" system - liner, insulation and outer sheet bonded together during manufacture.”
While the KS1000 LP and RW panels are conserving heat at the hotel, in another part of the building, similar panels have been used to create a new cold storage area, using an innovation from Kingspan Insulated Panels, the Modular Box, which combines very high levels of guaranteed thermal performance with ease of assembly and a fully supported fast track service.
Nineteen of the flat-pack, site-assembled, walk-in cold stores were installed at The Savoy. The Modular Boxes comprise high performance panels, which have a PIR Firesafe core and provide optimum levels of thermal efficiency with the crucially important fire protection required. David Blinkhorn, Managing Director of installer CCS explained:
“I inform my clients about the importance of having PIR as opposed to PUR insulation because of PIR’s superior fire properties. We specified The Modular Box cold rooms on the strength of their fire performance rating, as we felt this was important for the client. We now specify PIR to all our clients and not just in the UK. There is also increasing pressure from our clients to supply a superior product and I would like to think we have done so in using Kingspan.”
The fire rating is important because cool storage units create huge amounts of heat and most are located in commercial Kitchens where the risk of fire is huge. But the heat produced need not go to waste. At The Savoy, a heat reclaim system was installed with the Modular Boxes, so that their cooling systems also provide recycled heat to the hotel’s hot water supply to the bedrooms.
The refurbished Savoy has been reconfigured and restored to its sumptuous past whilst being brought into the 21st Century: the Thames Foyer, a large informal dining space at the centre of the hotel, has had its formerly boarded up deco glass cupola reinstated; and the Beaufort Bar has been created to one side of the foyer, evoking the glamour of the twenties; the comfort of both areas of course now enhanced by the very modern benefits of a high performance insulated panel roof.
