Building envelope compliance is non-negotiable

14221.jpg

In late 2013, Government changes to the Protection from Fire clause(s) of the New Zealand Building Code (C1-C6) deemed it mandatory for suppliers of warm roof materials to have their rigid insulation tested in order to demonstrate compliance to their new standards. Before going any further, the objectives of the current code for the Protection from Fire are as follows:

  • Safeguard people from an unacceptable risk of injury or illness caused by fire
  • Protect other property from damage caused by fire and;
  • Facilitate fire-fighting and rescue operations

Viking Roofspec’s Warm Roof assembly incorporates polyisocyanurate insulation (rigid foam panels) installed on the substrate ie: on the outside of the building.

Rigid foam needed to pass two lab tests: (i) AC1366 Flame Propagation - setting fire to core samples of foam to see how long they take to go out and (ii) ISO9705 –‘Room Test’ - lighting a fire inside a box made of foam installed on the outside of a steel tray substrate, to test a number of characteristics such as spread of flame.

With Kingspan Therma TR27 polyiso Insulation demonstrating the highest possible standards from these tests, along with Viking Roofspec – a market leader in warm Roof materials supply who operates by the mantra of continuous improvement (better than yesterday) – they formed a strong partnership in the supply of compliant components for Viking’s warm roof system.

Accordingly, Viking’s warm roof system – using TR27 Polyiso board, is one of the industry’s few systems to have achieved a ‘Group 1S’ Fire Rating from this testing, which is the highest possible rating in the industry.

It’s not only about compliance, it’s about safety! It’s paramount when specifying building materials, that the safety of the building inhabitants is the no. 1 priority.

When it comes to fire, what more appropriate system could be specified, than one with a Group 1S fire rating such as Viking’s Warmroof and WarmSpan systems?
