Moisture Content and Vapor Barrier for Wood Floors

For proper installation, wood flooring should be allowed to acclimate to its surrounding environment before it is installed. Too much or two little moisture in the flooring can cause it to bow, buckle, split, or crack after it is installed. In the dining room, Brickman shows Bob two ways to measure the moisture content of wood. The first is a traditional moisture meter that is stuck into the floor. The second is the FloorWatch system, which can be monitored remotely. The FloorWatch system monitors moisture levels, temperature, and relative humidity. It can be accessed over the phone or via a Web site. Before putting the floor down, Brickman applies a vapor barrier that is similar to an ice shield used in roofing. A different floor fastening system is being used in this room; rather than the nailing technique used elsewhere in the house, Brickman uses screws and wood plugs.

" Do you check that the -- the moisture well we check the moisture content with so little portable moisture meter in most cases. Put the -- and press a needle and gives us a reading. The other device we use we have a monitoring system install in the house have -- moisture meter relative humidity and temperature circuit we report the data. With telephone lines or web site. And it records the data and you can actually print out monitoring. And this is that print out of the current job we started monitoring on the 16 July report and it gives a continuous reading of temperature relative humidity and moisture content -- that's pretty impressed it's very convenient for those of us who have to drive an hour due to get the job fair here it eliminates that travel. Yeah now this is going to grind down that it's really -- to break the surface -- no not really it's just it's a very coarse abrasive it's actually fairly one that we used on our review. Before and what we're doing is we're just knocking the plaster dust and the other stuff off of it. At a secret ingredient is going to be. An ice shield right. Yes this. Bitumen membrane. That's primarily asphalt. And it's primarily used on roof applications. That we found itself. Really effective vapor barrier. So little power I think we'll let your son Richard be your over here yes it is this is Mike White paper and take -- the back craft. -- really tough to work with."

" It to the wall."

" Right to the wall then of course you'll be trimming every now and you'll put continuous sections. All across the shield all the way across the room before you start bringing in the wood now how it. Would use the same adhesive and nailing system that we have over there. No we can't apply adhesive because we don't have a bare wood floor to stick to I see so what we'll do is we'll increase our nailing pattern. I will also mark our joist location and we'll put screws. And we'll -- wood plugs matching wood plugs over the holes into the schools but the main thing -- to be assured that the finished job is not gonna cup -- exactly it's mechanical restraint."

Prefinished Wood Floors in the Modular Home
Prefinished Wood Floors in the Modular Home

Bob Vila takes an early interior tour of the modular home. Bob is in a 15-foot-wide-by-48-foot long section. The flooring and walls are almost complete and much of the molding and cabinetry is laid out and ready to be installed. Bob points out an archway between the kitchen and breakfast nook�one of the pleasant design surprises that can be added to a custom modular home. The floors are Bellawood�s Northern Red Oak with a gunstock finish. The darker finish gives a more sophisticated and formal look to the room. The hardwood floors are installed in the modular home just as they wood be in a site built home. Mike Snyder from Mike�s Flooring, a flooring sub contractor in the Simplex plant, points out the quality of the Bellawood noting it has very few flaws and a durable finish. The flooring is left incomplete where two pieces of the modular home are to be attached. On site, quick work will be made of the few details left when the large modular sections are joined.

White Oak Hardwood Flooring Installation
White Oak Hardwood Flooring Installation

Now that the WarmZone radiant-floor heat has been installed, it's time to put the finish flooring on. The homeowners selected a Bellawood white oak, tongue-and-groove floor with an oxidized finish for a 50-year guarantee. Since the flooring will be nailed over the hyrdronic heat tubing, it is critical to avoid puncturing the tubes. General contractor Tim Berky is installing the flooring perpendicular to the tubing, which allows him to see the Pex at all times and avoid nailing into it. Berky shows Bob how he began the installation with the second course cut to receive the supply and return pipes and sited half way over the first loop, which initially runs parallel to the wall and is hidden from view. By starting his courses this way, he can set the power-assist nailer to drive the two-inch galvanized staples at an angle just above the tongue without fear of puncturing the tubing. While Berky shoots the staples, Bob points out how the entire floor and substrate is effectively a green application since it is all wood, which is a renewable resource. The advantage, he says, is that trees are planted every time the resource is used, resulting in increased planting and forest protection. The wood floor will cover the entire space, even under the cabinetry and appliances, to create an even floor and provide full finish flooring should the homeowners wish to remodel in the future.

Discussing the Bellawood Maple Hardwood Floor
Discussing the Bellawood Maple Hardwood Floor

Tom Sullivan of Bellawood is in one of the four Mashpee affordable homes where they have donated hardwood flooring for the living room, dining room, and kitchen of each house. This 3 1/4 inch natural Maple flooring has color variations, tight knots, and more visual wood character than a select grade. Like the select and rustic grades, this Maple flooring is 12 percent harder than a Red Oak floor and will last a lifetime. Sullivan shows Bob a prefinished, micro-beveled plank that comes ready to install with a variety of lengths ranging from one to six feet. Bellawood provides a 50-year finish warranty on its flooring, which has eight coats of an aluminum-oxide based semigloss finish. Bob notes how the crew has positioned the pieces in advance to avoid lining up seams and to ensure an aesthetically pleasing layout. Sullivan points out that they have put rosin paper over the plywood subfloor and under the hardwood installation to combat squeaking.
