Report

Cembrit B5 

B5 fibre cement corrugated sheet was chosen as part of a unique design project to transform an old builder's yard in East Dulwich, into a contemporary family home. Christened by some as the ”urban cowshed”, the Yard is a property which has been designed by the owner occupiers Kevin and Denise Fox. Combining light and space, the construction houses bedroom and workshop wings around a courtyard. Courtyard walls of translucent sheet provide light and a feeling of space to the double height living space with roof, rear and side walls clad in Cembrit B5 corrugated sheet. With its ”urban” grey colour and symetrical deep profile to replicate the functional use of the Old Yard B5 corrugated sheet keeps the building to its heritage and current surroundings. B5 provided a perfectly scaled corrugated sheet for the outer skin of the roof and walls of The Yard, displaying a more modern and deeper profile than the typical 3 inch profile corrugated sheeting. The broad corrugations create a profile that gives the roof a permanent feel, unlike the ”bike-shed” appearance of the smaller more commonly seen 3” profile. Designed to the Passivhaus standard, combined with imaginative use of contemporary building products the project was an obvious candidate for Channel 4 television’s Grand Designs hosted by Kevin McCloud.

Fibre cement has several advantages over metal sheeting for residential buildings, such as rust resistance, porosity to vapour yet rain resistant. Fibre cement is also not as noisy in the rain.

B5 is available in 11 different lengths, ranging from 4’ 6” to 10’. It is approximately 40% wider than the older 3” profile design, offering better coverage per sheet. The broader corrugations are designed to have a greater water carrying capacity than the 3” profile and can consequently be used to a lower pitch and with smaller overlaps.
