What should you consider when choosing 1.5″ x 5.5″ boards?
- Intended use: Furniture, decking, or framing? Shorter HDPE boards suit modular furniture; longer boards suit continuous deck runs.
- Climate and exposure: UV resistance and color stability are vital for sunny environments; wood requires protection from moisture.
- Installation and maintenance: Plastic boards install like traditional lumber but require less upkeep; wood requires finishing and periodic sealing.
- Color options: If aesthetics matter, plastic options come in multiple colors; wood offers natural tones and staining possibilities.
How to compare the five options?
