Some of you may have seen the 60 Minutes piece about Lumber Liquidators (LL) this past Sunday. If you haven’t, I encourage you to do so (the youtube link may be liable to change but here’s a current link to the report). Reading with interest the blogs and feedback on their web and Facebook pages, and from our experience here at Planet Hardwood, I’d like to dispel some commonly held misconceptions:
- Within the industry “laminate” refers exclusively to plastic laminate which is the product category in question. This product is a layer of clear melamine plastic over a picture of wood (or tile or your cousin Henry) on a substrate of high density fiberboard (HDF). Outside the industry it is very common to incorrectly include wood engineered flooring in that category of “laminate” since thin layers of anything satisfies the dictionary definition of that word. Formaldehyde emission mis-labeling is not a problem in the wood business. It’s about as unlikely as finding something other than rice in the rice box at the supermarket.
- Not everything produced in China is suspect or deficient. Also, the Chinese don’t conspire to mis-label and confuse. Remember, this is a factory producing a private label product to a Lumber Liquidator specification packaged in a box designed by Lumber Liquidators. Lumber Liquidators brands it and that’s how they conduct their entire business. They’ve never produced a square foot of their “own” flooring. The Chinese mill managers immediately answered the tough questions posed by the undercover 60 Minute “buyers” in an entirely honest and forthcoming manner. This has also been our experience at Planet Hardwood when dealing with Chinese mills. You either pay for quality or pay for crap… there are no secrets. The customer is boss.
- Planet Hardwood decided years ago not to sell plastic laminate flooring. Or carpeting. Or vinyl. All of these products leave toxic trails in production, have a limited life span, will spend most of their time on this earth leaching poisons into the environment, and are unhealthy to live with while in your home.
At Planet Hardwood we get a full range of reactions to the consideration of engineered wood flooring. Engineered wood flooring is an all-wood floor that puts the specie one desires on the top layer only. The rest of the thickness has layers of wood arranged alternately lengthwise and crosswise thereby making it stable.
Engineered wood in other building applications is either fundamental (like plywood) or a signature of quality (like joists and rafters). In wood flooring it’s perceived most of the time as a “less-than” option to solid wood flooring.
Some of this is sound judgment, as the cheapest, crummiest, poorest performing, ugliest (in our opinion) wood flooring is engineered.
But, the best performing, most versatile, most efficient, most developed, most stylish wood flooring in our showroom is also engineered.
So engineered wood flooring occupies every rung of the ladder in terms of quality and value, but most people’s frame of reference is with the crummy stuff.
Sustainability and Engineered Flooring
I’ve come to appreciate engineered flooring from a resource-use, or sustainability, standpoint.
The North American profile for solid wood flooring is pretty familiar: 3/4″ thick and tongue-and-grooved. I distinguish it by North American because it’s fairly exclusive to us. They take a different approach in the rest of the world to wood flooring, and here’s one of the reasons why:
The only theoretically usable portion of that 3/4″ tongue-and-groove profile is from the top of the tongue to the surface. However, when refinishing the floor, one of the first investigations of a sand-and-refinish crew is how much of that distance above the tongue is left from the previous and/or initial sanding(s). If anything approaching half that distance is gone, they run the risk of making it too thin on the groove side to survive a footfall without cracking.
The equipment is simply too big and heavy and the sandpaper too gritty to offer a consistently fine enough tolerance to avoid that risk.
So in practice, the only usable portion of that piece of solid wood flooring is about half the distance from the tongue to the surface. With our 3/4″ profile that translates to 1/8″. This end result is that with a solid wood floor around 80% of the resource is wasted.
A quality engineered wood floor offers the same usable top wear layer as a solid wood floor with a support package of ‘lesser’ woods arranged in an alternating 90 degree stack. This makes the flooring six times more stable than its solid counterpart, allowing its use below-grade and/or directly on concrete.
The lesser woods could mean lower grades of the same species, faster or plantation-grown species, pre or post production wood waste or plywood. All of these options take the pressure off the primary forest and ultimately maximize the yield from the log.
Making the right choices when sourcing wood
Some of the flooring mills that supply us have the versatility to take the raw material downstream in production and make either a solid or an engineered floor. In two recent cases we directed the mills to produce the engineered format.
In one case, it involved a species available to us only sporadically. It comes from an environmentally certified mill that manages their forest to the highest environmental standard in the world. The restrictions result in a harvest-driven menu of choices, not a market-driven menu. Years could separate access to this species. By maximizing the usable material through the use of the engineered format, more total square feet of flooring becomes available.
The other case involved a figured domestic hardwood rarely found in wide dimensions, but the raw material could result in flooring up to 7″ wide. It would have been irresponsible to waste 80% of the Canarywood or Birdseye Maple resource. Instead, we multiplied the square footage.
All of this is to point out that whether we’re looking at sustainability, product availability or performance aspects like stability, a quality engineered wood floor is not a compromise in any way and often, it’s the best recommendation.
Job site conditions
Check the jobsite for conditions that will result in excess moisture or high humidity.
Surface drainage should be away from the house. The slope should be minimum 6″ in 10′. Gutters, drains and downspouts should be unclogged and functional, draining water away from the house. Eave overhangs should be sufficient to prevent rain from flooding the foundation.
If there is a crawlspace, it must be cross-ventilated with a total ventilating area exceeding 1 1/2% of the first floor area, with no dead air spaces. For example, a 2,000 sq. ft. crawl space must have 30 sq. ft. of year-round open venting area.
If the ground under the house feels damp, or is giving off excess moisture, lay a 6mil. polyfilm vapor barrier on the ground in the crawlspace below the installation area.
Remember to take into account seasonal changes in relative humidity which might affect jobsite suitability. (more…)
Wood floors are beautiful, unique, and with the proper care and common sense will last for as long as the building is standing. Most wood flooring problems occur due to abrasive material scratching the finish, excessive water or moisture exposure, or subjecting the wood to an extremely dry environment. The following suggestions will help take the guesswork out of proper maintenance. (more…)
The reason for wood to be in the environment of the occupied building prior to installation is to “acclimate” to the prevailing relative humidity (RH). Wood is hygroscopic, that is, it acts like a sponge, either soaking up moisture or giving up that moisture to a drier environment as it arrives to a balance with its surroundings. This balance, where the wood is theoretically inert, is called the “equilibrium moisture content” (EMC).
During construction, especially new construction, there are wild swings in RH (more…)
