Expansion Joint Systems for New Zealand’s Seismic Building and Design Changes

By inherently factoring all aspects of the new seismic design and assessment criteria reflected in the Building (Earthquake-prone Buildings) Amendment Act 2016, which introduced major changes to the way earthquake-prone buildings are identified and managed under the Building Act 2004 throughout New Zealand, the joint systems Facade Interaction Joint utilises unique manufacturing and design to encapsulate and protect entire building facade envelopes from the effects of fire, wind and acoustics whilst compensating for thermal (low range) and seismic (high range) movement.

joint systems, in conjunction with some of the world’s leading architectural designers and product specialists, developed the Facade Interaction System specifically for the new changes to the Building Act (Amendment) in 2014 by adding a new level of acoustic performance to Preformed Polyurethane Expansion Joints. The Amendment in 2016 has been added after several years of strong seismic activity with the Public’s safety in mind.

The recent changes addresses New Zealand’s “Degrees of Seismicity” as they reflect three seismic risk areas or zones, and sets time frames for identifying and taking action to strengthen or to remove earthquake-prone buildings entirely.
