Conventional Timber Systems
For 30, 60 and 90 minute fire ceilings
Building Regulations Document B determines the ceiling type that is required depending on the type of building under construction and associated usage.
The ceiling types are designed to provide protection to the floor above in the case of a fire for a duration as specified by the document.
Using JCC's Fireguard downlights ensures that this specification is maintained even when downlights are installed in the ceiling.
I-Joist Timber Systems
For 30 and 60 minute fire ceilings
Timber I-Joist systems offer builders an alternative to solid beam ceiling constructions. These products are manufactured from laminating layers of wood together to produce I-Joists. This makes them lighter and easier to manoeuvre, together with the benefit of being able to span greater widths without undue flex in the floor system. However, as these timbers are thinner, there is much less material to resist the passage of fire and thus luminaires that are suitable for solid timber floor constructions are not necessarily suitable for I-Joists. Thus, JCC has spent considerable resources working in conjunction with BRE and Chiltern Fire International to ensure their luminaires are suitable for the majority of I-Joist floor systems.
