uPVC is the most widely used material for manufacturing windows and doors. Thanks to its durability, excellent insulating capacity, low maintenance finish and customisation options, it has remained popular with homeowners since the first uPVC windows of the 1980s. uPVC windows today, however, are vastly improved compared to their original 1980s counterparts. With such a diverse range of benefits, it’s perhaps no surprise that uPVC windows are still so popular.

What is uPVC?

PVC is a chemical compound consisting of chlorine, carbon and hydrogen. During production, various additives are incorporated to create different qualities depending on the product being made. For windows, these may include heat stabilisers, UV stabilisers and flame retardants. Additives help the finished product to retain its strength and consistency of colour.

uPVC stands for unplasticised polyvinyl chloride. It is a rigid plastic with excellent resistance to chemicals, water oxidisation and sunlight. It is unplasticised, meaning that no chemicals have been added to soften the material, therefore creating its rigid structure. uPVC is a cost-effective material and is used widely in the construction industry for making window frames, guttering and pipework.
