MATERIAL CAPABILITY

Outdoor UV Exposure and Colour Retention

Project Background

Exterior trees fail on colour, not on structure. A tree that fades in a season of direct sun leaves a visibly washed-out feature in an entrance or plaza, even though the trunk is still perfectly sound.

Specifications

Foliage ratingUV50+ stabilised
Test standardASTM G154 accelerated weathering
VerificationSGS verified 3–5 year colour fastness
HardwareSalt-air resistant stainless fixings for coastal sites
DocumentationTest reports issued per project

Client Challenge

Desert and coastal sites are the harshest cases: high UV plus salt air degrades both foliage colour and metal fixings. Specification clauses written without test evidence give the supplier room to substitute a cheaper foliage.

Solution

We specify UV50+ foliage tested to ASTM G154 and use stainless fixings on coastal sites, then issue the test documentation with the project so the specification you paid for is the specification you receive.
