WHY IS UPVC COMMONLY ADVERTISED

Why is UPVC commonly advertised?

Before the European standards decided to change UPVC to PVCu, UPVC was regular in English due to the influence of Great Britain's public domain. Great Britain's public domain was a more popular naming convention for the materials. That is why assemblers use both PVCu and UPVC. Therefore, PVCu and UPVC are the same materials and purchasers should know this fact while acquiring new building development products.
