CFS鈥� patented design consists of channels connected by a bobbin that allows for both vertical and horizontal movement and so requires no movement joints.
Fa莽ade retention projects are common where there is a need to keep an existing fa莽ade to preserve architectural heritage.
鈥淭his product was developed as an answer to our project at Regent鈥檚 Park,鈥� said CFS chief executive Henry Chart. 鈥淚n this case, the big challenge was the lack of movement joints in the fa莽ade, despite the need to control the brick expansion.鈥�
One of the most technically challenging aspects of this project鈥檚 fa莽ade鈥檚 rebuild, he said, was to achieve a historically accurate elevation that employed modern performance requirements while controlling its movement and cracking. Movement joints, being a modern concept, were not acceptable on a Grade I listed fa莽ade.
Iain McLellan, from project architect Studio PDP, added: 鈥淲hilst movement joints are nowadays used in modern construction, they are not possible to be used in Grade I-listed fa莽ade. However, in addition to the brick expansion, there is also concern about ground-born vibrations due to the proximity to three London Underground railway lines. The structural design provided by CFS answered this issue.鈥�
