Last week we discussed the advantages of using closed cell underlayment for your floating wood floors. This week we’ll switch gears and have a look at AcoustiCORK underlayment, a natural product that provides a similar level of insulation, sound deadening and resistance to mold and mildew.
Are you better off installing cork underlayment, rather than synthetic foam? Or does this green product require extra steps and added investment for optimum reliability?
What is Cork Underlayment?
AcoustiCORK underlayment comes in rolls, just like the closed cell product. Contractors install this product under floating wood floors, and the product may also be used as the underlayment for nailed down hardwood and engineered wood floors.
Underlayment provides insulation against heat loss, sound, and moisture. Quality underlayment adds cushion to your flooring for a more comfortable, durable surface.
Three Advantages to AcoustiCORK Underlayment
This natural product is a green choice for your home, made from a renewable resource. Cork is biodegradable and affordable, and one cork tree can provide countless rolls of this product over its lifetime. Opt for cork underlayment over closed cell products for a more environmentally friendly solution.
Cork contains tiny air pockets that provide insulation naturally. The growth pattern of this bark provides a cushion effect and produces an excellent barrier against sound and heat loss. Closed cell products mimic the natural formation of cork; high quality cork brands provide the same level of durability and performance as synthetic brands. In addition, cork does not emit the synthetic odor commonly found with closed cell products.
Cork also contains suberin, a natural substance that resists bacteria and fungi. The presence of suberin makes cork anti-allergenic, and also creates an effective barrier against the growth of mold and mildew. If you suffer from asthma or frequent allergies, trust the make up of cork to protect your health.
Disadvantages to Using Cork Underlayment
Many homeowners opt for closed cell in the basement or on concrete subfloors. This product offers superior protection against moisture, although cork comes in a close second. Remember that cork underlayment is water resistant, and will naturally resist fungal growth due to moisture. But cork is a natural product, and on its own cannot provide a barrier against water seepage.
You’ll need to use a poly moisture barrier between the concrete subfloor and the cork to provide optimum moisture protection. This process allows you to enjoy the benefits of using cork, without the worry about moisture and water damage.
For a sustainable choice that offers premium noise reduction and insulation, AcoustiCORK underlayment is an excellent choice. Ask your flooring specialist whether your application requires a layer of poly for optimum moisture resistance. In any case, cork underlayment costs the same as closed cell products and provides greater environmental benefits, both now and far into the future.
