Rubber Cork Underlayment

  • Why rubber cork underlayment?
 

AcoustiCORK RC500 rubber cork underlayment offers superior sound resistance while providing crack suppression with superior comfort. Comprised of recycled materials, this environmentally friendly product provides cushion underfoot as well as reducing sound transmission and impact sound such as footsteps. Rubber cork underlays are great for residential and commercial use.

Do I REALLY need underlay?

  • Yes, most definitely.
 

Underlayment is an amazing invention created by the flooring gods out of necessity. Underlay has an impressive list of benefits, including: adding warmth to your floors so your feet aren’t so cold on new tile flooring, adding comfort and a slight ‘give’ underneath wood or vinyl floors, reduced sound transmission (great for houses with noisy teenagers!), as well as reducing in room step noise. The image to the left is a very simplified example of using underlayment versus not using it, but as you can see the benefits greatly outweigh any reason not to.

Making your house a home

  • Products that work together
 

A favorite for use with ceramic tiles and hardwoods, laminates, and natural stone floor tiles. Rubber underlayment should never be used with vinyl flooring, VCT, or linoleum flooring as it could potentially stain these materials.

Thickness

  • What does it mean?
 

Underlayment with a thickness of up to 5mm thick are great when it comes to residential or commercial use, with all flooring types. When you get to more than 5mm thick, these are really great for installations where you need to add thickness to match up with an adjoining/existing floor surface.

IIC / STC Ratings

  • What do they mean?
 

IIC stands for Impact Insulation Class, which refers to impact sounds such as shoes hitting the ground, dropping a cell phone, or other scenarios where something it dropped or impacts the floor. STC stands for Sound Transmission Class, which refers to any audible noise (not an impact) such as music playing aloud, a conversation, or a loud television, for example. With both of these ratings systems, the higher the number rating is for the underlayment, the better it will suppress sound, and the quieter a room will be. You may want to pay close attention to these ratings when shopping for underlayment if sound reduction is important to you.

Can the AccoustiCORK RC500 underlayment be used underneath the 8mm Strong Rubber Tiles-Designer Series? I have an unfinished basement room I'm planning to turn into a home gym/theater room—currently a concrete slab. I was thinking of using DriCor subfloor membrane panels over the concrete, then Accousticork over the plywood panels finished off with the 8mm Strong Rubber Tiles. Does this make sense?

Ordered samples and decided upon RC500. Glues onto concrete and flooring glued on top. Professional installation, but was easy to install. Love it over the cork only product. Great quality and worked very well in reducing sound and vibration. Would highly recommend.

Very happy with the underlayment quality. Only issue I had was processing time took nearly 3 weeks, it was over the holiday's so some delay could be expected. However the customer service the two times I dealt with them were very helpful and went out of their way to get answers. Overall very pleased and would buy again.
