Can I use TimberTech DrySpace with TimberTech Floorizon Deck boards?
Yes. With proper installation, TimberTech DrySpace can be used with Floorizon boards. The moisture will be carried away from underneath the Floorizon boards. It is the moisture underneath the Floorizon boards that could cause cupping. In addition, since the V-Panels are cut 75mm from the beam or rim joist, there should be some air flow around the planks.
