Leading fi re safety
and certifi cation
Solid joist
Conventional solid timber joists are the
traditional ceiling joists which are typically
used in older, existing domestic buildings.
They are widely found within internal fl oor
and separating constructions.
I-joist
I-Joists are strong, lightweight wooden joists
intended for domestic applications, and are
used in new builds throughout the UK. They
continue to grow in popularity as they have
greater strength to weight ratio and are less
likely to bow compared to other options.
Steel open web joist
Steel open web or POSI joists combine the
lightness of timber with the strength of the
Posi-strut steel web, allowing you to span
far greater distances than alternative timber
products. This can be used across a wide
range of applications including domestic,
industrial and commercial.
PART B
Fire safety, providing suitable
protection for people to escape
buildings with the time gained by
having provisions in place.
PART C
Resistance to contaminants and
moisture, preventing moisture
or contaminants from passing
through a downlight into voids.
PART E
Resistance to the passage of
sound to ensure that people have
a reasonable degree of acoustic
privacy in their homes.
