Flooring Types

Solid T & G	Nail-down installation over wood subfloor Made of a single piece of wood milled with an interlocking joint (Tongue & Groove) usually 3/4" or 1/2" thick. Most versatile type of flooring for custom detailing and species choice.
Floating	Best used over concrete, but can be installed over any type of subfloor by gluing or clicking planks together over a cushioned vapour barrier.
Gluedown	Best used over concrete, but can be nailed or glued to plywood / OSB. A multilayered engineered flooring that comes as a single strip that is assembled in a manner similar to plywood. The strips are glued or nailed down one by one producing the look or a traditional solid wood floor.

The type of wood you use depends on the type of subfloor system that you have

Plywood on Joist Most common type of subfloor for single family homes with basement or crawlspace. Suitable for all types of wood floor installations, but we usually recommend solid nail-down floors.

Concrete

Most common type of subfloor in newer condominiums and houses without basements or crawlspaces. Best suited to glue-down or floating installation of engineered wood floors. Radiant heated concrete has special warranty considerations.
