Suitability
Bamboo is usually available as a laminate or engineered board. This is a more stable product than solid timber as it is cross laminated, like plywood, with a bamboo upper layer, and its moisture content is less critical. It can be laid directly over the underfloor heating as a ‘floating floor’ or secret nailed to battens or joists. Unless installed over a screeded slab, engineered boards of less than 20mm thickness should be supported and fixed to additional decking material to lend suitable structural support. Underlays such as Duralay Heatflow by Interfloor are particularly suitable when floating the boards over screed.
