St Lukes Hospital

The largest single project using JJI-Joists to date.

Fourteen blocks of new build single storey timber frame wards with mono pitched roofs averaging 2150m2 roof area per block and a total of 1300 JJI-Joist roof and floor cassettes. 

Deep JJI-Joists are an ideal solution to achieve long clear spans. Mono-pitched and flat roofs are extremely common in the public and non-residential sectors and are therefore suited to using JJI-Joists when an open plan environment is desired below. In the last 2-3 years the use of JJI-Joists in commercial and industrial buildings, as opposed to housing, is becoming more popular.

Historically Architects and Engineers would have specified steel or timber roof trusses to create the mono-pitched and flat roofs that many of these buildings require. However now more specifiers are looking to timber I-Joists to achieve high levels of insulation and a thermally efficient and sustainable roof structure.
