JES

Joist End Support

The JES is a two piece metal-work system which enables the use of engineered timber I-joists in loft conversions, offering a safe and economic alternative to the traditional method which requires steel girders.
It provides reinforcement to the joist ends where they are cut to fit within the
eaves of the existing roof. Each JES is supplied as 2 plates, as required for each joist end.

  • The I-joists are installed from wall plate to wall plate, which means there is no need for a costly Party Wall Agreement.
  • Steel beams can be eliminated, so there is no need for a crane, or to remove all the roof tiles.
