When storey ceilings separate two usage units, installation space beneath the fire protection layers can be created – by configuring with so-called “Plus layer” - which minimises penetrations.
Not only in building classes 4 and 5 (medium-height buildings) but in general in multi-storey buildings, rising ducts, sealed off by separation components, must pass through. For a highly fire retardant and fire resistant design Lignotrend uses various firestop solutions of the Hilti company, which are dry and easy to install.
They are demonstrably suitable for installation in Lignotrend cross-laminated ceilings.
If, in wall components, plaster boards sealed against fire are penetrated by electrical installations (e.g. sockets, light switches) there is a fire-resistant separation solution inside the wall, into which simple cavity sockets can be installed. Intumescent materials there hinder the penetration of fire into the wall.
