About our Trusted Go-To Product
Deckorators Voyage Decking
We use the Voyage series because it is a composite made up of limestone instead of wood like so many competing brands of decking used. Limestone does not get scorching hot in the sun and will not expand or contract. The material is very slip resistant as well.
Deckorators Voyage Composite is splinter-free, maintenance-free, and long-lasting. It’s an ideal choice so you can spend your time enjoying the deck rather than working on it.
