Thanks for the question, it’s important to think about material choice when specifying enclosures for outdoor use.
We normally wouldn’t recommend Polystyrene enclosures for outdoor use, simply because they are prone to UV damage which means that they will not be as reliable as polycarbonate of glass reinforced plastic (GRP).
Polystyrene enclosures are typically a low-cost option which can make them a tempting prospect when specifying for a project – and when used internally it’s often a perfectly suitable choice. For outdoor enclosures though, you will definitely make your money back by specifying the better material first time.
Spelsberg has a wide range of polycarbones and GRP enclosures which you can find by visiting our product finder here: https://www.spelsberg.co.uk/product-finder/
