We recently had occasion to be drawn into the realm of structural engineering with regard to concrete floor slab penetrations. The issue is all too common: no provision made for power or data cables (and other services) to pass through concrete floor slabs. 

A dedicated weathertightness layer can help protect building frames after a seismic event — ensuring that water damage doesn't occur through minor cracks or damage. 

Designers, project managers, installers and building consent officials exercising duty of care responsibilities would positively contribute to raising the bar on all passive fire protection installations in NZ.

In discussions with designers on interior fit-outs recently, it became apparent that there was a requirement for a fire stopping solution that was temporary in nature.

The homeowner pays the upfront cost of a hypo-reactive building, or the ongoing costs of a hyper-reactive building.

The hydrosafe value quantifies the level of protection for your construction against increased indoor humidity levels during the construction phase (building moisture).

It is very important that all aspects of the window are taken into consideration; frame system, double glazing, window size and the connections between the window and the wall.

Engaging a passive fire specialist can help determine if the proposed installation method of fire stopping will comply with relevant fire test results or if an alternative solution is possible.

How to ensure standard thermally-broken windows are positioned to succeed.

By making provisions for passive fire penetrations in pre-cast concrete slabs, you can save on costly concrete drilling and reworks; economies of scale make it a 'no-brainer'.
