At Trade Insulations Ltd we wanted to see what our clients thought…. which brand 100mm PIR Insulation Boards has the best thermal conductivity?. We asked our marketing team to put a vote together to see what our clients thought. Over 2500 of our clients come back to us and these are the results…

To make it a fair test we waited 2 weeks before uploading the results –

Kingspan – 28%
Celotex – 20%
Recticel – 16%
Ecotherm – 14%
Quinn Therm – 7%
Xtratherm – 6%
IKO – 5%
Ballytherm – 4%

And the Answer is…

All of the Above hold the same thermal conductivity on 100mm Insulation Board of 0.022W/mK. Contrary to popular belief all of these brands work towards the industry standard of 0.022W/km. So, no matter the PIR insulation brand either Celotex, Recticel, or Kingspan they all do the same job.
