Dilly hotel

Hundreds of FD30 fire doors at a historic hotel in London’s Piccadilly have been fitted with a variety of Norseal intumescent and fire-rated products, many of them made bespoke by Norseal, to make the job quicker, easier and trouble-free for specialist joinery and interior fit-out contractor NBJ (London) Limited.

London’s iconic Piccadilly Hotel, later renamed Le Méridien Piccadilly, is currently undergoing an impressive restoration and transformation programme. The hotel, located at 21 Piccadilly, Mayfair, dates back to 1908, and this latest transformation sees The Dilly redefined and restored to its distinctive London style. The hotel incorporates 283 rooms and suites, various restaurants and food outlets, a health club and spa, a dance studio, and seven meeting rooms. The designer for the project, Aspinall Creative, has drawn inspiration from the city of London's heritage, with strong design connections to an era of elegance and the hotel’s cosmopolitan heritage.

Joinery contractors NBJ, working on phase one of the restoration project, installed over two hundred FD30 fire doors on bedroom doors at the Dilly Hotel using a variety of products from Norseal to maintain fire integrity throughout. As well as a variety of intumescent strip seals, NBJ fitted Norseal’s NOR810 single-actuated bottom edge drop seal for its acoustic and smoke rating.

 A significant benefit for NBJ installation was Norseal’s intumescent lock kits, cut to bespoke size for the hotel room door locks, saving NBJ time, money and hassle on site. “We always get great service from Norseal, and these Interdens lock kits certainly saved us a great deal of time on such a large project, and we were always confident that they would be perfect every time,” says Craig Smith from NBJ. “Having the pre-cut intumescent kits, along with intumescent strip – in white to match the doors – drop seals and fire rated door viewers all from one place delivered without fail on time was a great help to us in getting these doors completed to the highest standards on time to meet the project’s tight deadlines.”

Norseal supplies a variety of low-pressure graphite and Interdens intumescent sealing solutions for a range of ironmongery products, including hinges, flush bolts, door closers, and locks, all designed to help prevent the transfer of heat through door hardware during a fire. In accordance with BS 476-22, they provide up to 120 minutes of fire resistance and can be designed and bespoke in-house, ensuring they are right the first time, every time, and do not need to be cut or adjusted on site.

The NOR810 is a single-actuated bottom-edge drop seal for acoustic and fire-rated timber door sets. It has been tested to withstand one million cycles and meets all applicable standards. It is available in thirteen lengths, ranging from 320 to 1535mm, as standard. In addition, Norseal can cut accurately to any length using Europe’s first custom-made drop seal cutting machine. The machine will cut any drop seal to the exact size needed, ready for next-day delivery, without damaging it, while maintaining the fire, smoke, and acoustic integrity of the door. Every door seal cut to size by Norseal comes with a one-million-cycle guarantee.
