Here at Celotex, we know that third party approvals play a key role in distinguishing product performance between different manufacturers. Wanting to eradicate the perception that all PIR insulation is the same, we recognise that by possessing 3rd party approvals for a number of our products, we are one step closer to accomplishing this. We've acquired accrediations for ISO9001, ISO14001, CE marking and BRE fire, security and environmental standards.

Take a look at our accreditations and be assured that you are guaranteed to receive a product that meets your project specification:
