QuadCore 2.0 offers increased recycled content and two-hour fire rating

THE LATEST development of Kingspan’s QuadCore 2.0 self-blended insulation technology demonstrates that innovation and improved product performance need not come at the expense of the planet.

QuadCore 2.0 is made with a formulation containing a raw material that uses 40% recycled PET. This innovative formulation has met the requirements of a two-hour fire resistance period in third-party fire tests for insulation and integrity, making it the first closed-cell insulated panel system to achieve this rating.

QuadCore 2.0 is a key step towards one of Kingspan’s ‘Planet Passionate’ goals of ensuring the company recycles 1 billion PET bottles by 2030 and QuadCore Technology uses recycled PET by 2025.

The above EN 1364-1 fire resistance test was carried out by WarringtonFire using the new generation QuadCore 2.0 with a 220mm thick and 1000mm wide cold room through fixed insulated panels, thus satisfying the requirements of EI 120 (including more anon). This test result was obtained without the need to use sewing screws to fix the panel joints. During testing, the oven reached a temperature of over 1,000 degrees centigrade.

Closed cell insulation

Mike Stenson, Head of Innovation at Kingspan, commented: “Since its launch in 2016, QuadCore technology has been at the forefront of innovation in closed cell insulation, with an unrivaled combination of thermal efficiency, fire performance, environmental references and warranty offer. Within our innovation and chemical development teams, we continuously strive to take each of these performance factors to the next level, creating insulation technology that is truly designed with future building performance in mind.

Stenson continued, “Including recycled PET as a raw material in our formulation is a key goal for us globally as we work towards a more circular approach, with our new breakthrough significantly improving performance. The expertise in mixed chemical systems that we have had since the acquisition of Synthesia in 2017 has undoubtedly contributed to making this radical change possible in terms of both durability and fire performance, as this result of the EI 120 test.

The QuadCore 2.0 line of insulated panels is currently undergoing a rigorous testing and certification program, including reaction to fire and measurement against various insurer-backed standards. Once completed, the first products containing the new core should be ready for commercialization this year.

What is the EI 120?

Fire resistance is a measure of how long building assemblies can withstand and contain a fire. The measure is expressed in integrity (E) which is the ability to resist exposure to fire on one side, while stopping the passage of flames and hot gases to the unexposed side for a certain time.

It is also expressed in isolation (I). The building element will be able to stop the passage of heat to the unexposed side up to a maximum surface temperature value of the non-fire side for a period of time.

Essentially, EI 120 means the product provides certified integrity (E) and insulation (I) performance for 120 minutes.
