Flooring and Carpeting /installing underlayment under vinyl plank flooring

Hi John,

I am going to install a floating vinyl plank flooring system in four connecting rooms in my home. Three rooms have carpet that I will remove. Then, the kitchen/dining area has sheet vinyl, which I intend to leave intact due to asbestos issues. What I’d like to do put an underlayment over everything to give myself a nice clean surface and to eliminate the transition areas from the vinyl to the subfloor when the carpet is removed. So, I have a few questions

1. I will use 1/4″ material, but is there are specific type of plywood that I need to use? What about cork, which might be the easiest to install?

Since I will be raising the height of my floor by 1/4″ with the underlayment, how can I deal with the door thresholds? Really, I just need to be concerned with my front door and the sliding patio door that’s in the dining area.

Hi Matt;All vinyl plank manufacturers have done extensive testing for the manufacturing of the product, the installation techniques needed, and the maintenance. before bringing their products to market. If you check with various manufacturers of similar products, there are different installation and maintenance specifications required. Therefore, you need to find out the name of the EXACT manufacturer of the flooring of your choice, ‘google’ that manufacturer’s name and visit their website, on which you will find installation specifications and maintenance information that you can download and read thoroughly. The information in those manuals should be followed exactly, including the cleaning agents used. If you can’t find the name of that EXACT manufacturer, please get back to me. The installation specifications list lots of important information including acclimation, installation procedures, acceptable underlayments, acceptable moisture barriers, how to handle threshholds, etc. On that website will be contact information, which is usually an 800#. Call it and speak with their technical services department to get any other needed information. ‘One size does not fit all’, so get the proper specifications. The maintenance information will also list lots of important things including proper cleaning agents and techniques, allowable footwear (some plank flooring should not be walked upon with high heels), the need for proper furniture leg protectors that must be constantly monitored and cleaned of imbedded gritty soils and changed when they begin to show signs of wear, etc.

I strongly suggest that you do NOT purchase any type of floor covering from one of those large home supply stores or over the internet. Shop at a local, reputable, floor covering dealer who can supply proper product, supply proper installation, if needed, warranty both of those things, and give you references, which you should check out. I also suggest that you do NOT purchase any floor covering manufactured by Shaw Industries or one of its subsidiaries, or any products offered by Lumber Liquidators.

Just some additional information;Remember what you intend to purchase is non-absorbing flooring, so harmful track-in soils, air polutants, allergents, etc. remain on the surfaces of hard surfaced flooring and become airborne with normal foot wear and normal home air currents, allowing the human lung to become the trap and filter for those soils. Depending upon the environment in which you live, you may find you have to maintain hard surfaced flooring on a daily basis.

One of the healthiest floor coverings is carpet. It has a pile that traps, filters, and holds those harmful soils until they are properly vacuumed away, and, on occassion, properly professionally cleaned away. The true cost of any floor covering is product, installation, and maintenance, over its useful life. Carpet costs less as a product, less to install, and less to maintain, over its useful life, even as much as 10 times less. Today’s carpets are extremely durable, can be totally recylable, are VOC (volatile organic compounds) free, etc. Visit the website of The Carpet & Rug Institute, carpet-rug.org, to learn true health information, obtain their lists of vacuums, spot cleaning agents, and professional cleaning systems they have tested and certified as being ‘green’, friendly to your environment, and proper for carpet. Once you take the time to explore those health issues, you may want to rethink your choice of floor covering. If you do decide to recarpet, please feel free to get back to me for construction specifications I would give you which you could use to shop.

Carpet was erroneously given a bad reputation as being unhealthy, when just the opposite was true, so visit that website, carpet-rug.org.
