Rhino Doors has successfully tested its full range of CPNI doors, with both single and double leaf variations achieving impressive results for fire integrity and acoustic attenuation. 

Following successful tests on its single leaf door in September 2021, the company put its double leaf CPNI product to the test in March 2022. 

The FD30 door, which was fire tested in accordance with EN1634-1: 2014, achieved the same 60-minute integrity rating as its single leaf counterpart and an insulation rating of 30 minutes. 

It was also tested to measure its effectiveness at sound reduction, achieving an impressive attenuation rating of R_w 40dB. 

Rhino has been producing CPNI doors for many years and is now manufacturing its range of personnel doors with fire and acoustic ratings as an option, to cater to the needs of its diverse client base and to deliver high-security products capable of withstanding complex environmental stressors. 

“We’re very pleased with the recent successful performance of our double leaf CPNI door”, said Ceri Couser, Head of Security Projects of Rhino Doors. 

“These fire and acoustic tests, which conclude our testing on our full CPNI range, solidify our industry-wide reputation for producing high-security doors built to safeguard people and assets in challenging environments. 

“As we continue on our path of growth, building on the successes of the last year, we’re delighted that our CPNI range continues to offer our clients the strength to protect.”
