The JJI-Loft system by James Jones & Sons Ltd. in conjunction with Simpson Strong Tie is a loft conversion system that is much faster and safer than the conventional steel girder method, more convenient to the home owner and less intrusive to neighbouring properties.
Until recently converting a loft or adding a room above a domestic garage required the installation of steel girders and penetrating party walls where adjoining properties are involved. The JJI-Loft system utilizes JJI-Joists and Simpson Strong Tie JES (Joist End Support) supports to permit floor joists to continue right into the eaves of the roof, thus providing useful storage space and an instant safe floor deck when boarded.
