uPVC and the Environment

A common concern and question when considering a new Double Glazed Greenhouse, Pavilion or Orangerie is the material the building is constructed from, it’s safety as well as the impact on the environment.

There are many misconceptions about uPVC and the impact this material has on our environment and our wellbeing i.e. being toxic or “it’s plastic will it burn and melt”. In this blog we will try to alleviate these concerns.

There is numerous test data available from uPVC profile suppliers on the fire performance and toxicology information regarding uPVC products, without us going into too much details here, general uPVC has a good resistance to ignition so has a low heat combustion/burning rate and is difficult to ignite unless of course there is a continuous source of ignition/heat, as with all material if this happens anything will burn eventually!

UPVC has a carbonaceous layer (or Char), this insulates the material and prevents flaming droplets, debris spreading, and smoke contamination etc. (unlike normal burning plastics, which almost turn “molten”) so the spread/damage to the environment is minimal.

Therefore UPVC is classified as a GOOD environmental product, unlike wood, where wood if ignited will keep burning and spread to other materials, which in turn could cause greater problems. This is the danger with Carbon Monoxide burning from other materials that ignite, therefore combusting and spreading.

UPVC seems to act as a fire retardant, and also the lead content has been removed so is significantly less toxic. So we would be more concerned with the materials stored within the garden building catching fire, than the UPVC garden products themselves!
