Testing & Compliance
Engineering acceptance of insulation materials relies on a traceable document chain. We provide the following documents with each batch to support sample submission and acceptance.
Provided per batch: test results for thickness, apparent density, compressive strength and fire performance travel with the goods.
Engineering sample testing is supported to standards such as GB/T 10801.2, with same-batch samples and sampling instructions.
The three management system certificates, the business licence and the construction qualification documents can be provided as copies and scans for tender requirements.
Tell us the element — wall, roof, underfloor heating or cold store — and the thickness required, and we will advise on common sizes to GB/T 10801.2, send samples and quote batch supply.
