Accessories for AcoustiCORK RR300
 

Description - AcoustiCORK RR300 Rubber underlayment has been specifically designed to be the best underlayment to use under floating floor systems. RR300 can also be used under other floors such as cermaics, harwoods and stone among others. This rubber underlayment can be adhered by adhesive, double sided tape, nails or staples and does not hold water, which helps make this underlayment resistant to mold and mildew. In areas where water may be present, a vapor barrier would be required to protect the flooring surface. But in areas where water would not be present, a vapor barrier would not be necessary unless specified by the manufacturer’s warranty. RR300 also has properties which aid in the suppression of cracks in ceramics, stones, and hardwoods due to subfloor fracturing. This ensures that your flooring surface stays crack free for the lifetime of the floor. This underlayment is also great to use under our Modular Flooring because it helps reduce the noise caused when walking or driving over them.

Recommended Uses - AcoustiCORK RR300 flooring underlayment is designed to be used in both commercial and residential applications.

Features

Rubber Underlayment

  • Why rubber underlayment?
 

AcoustiCORK RR300 rubber underlayment offers superior sound resistance, is versatile and resilient. Comprised of recycled materials, this environmentally friendly product provides cushion underfoot as well as reducing sound transmission and impact sound such as footsteps. Amazingly, a 2mm thick rubber underlayment has similar testing numbers in sound resistance as compared to a 6mm thick cork underlayment.

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 hard plastic garage tiles, hardwood flooring and 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.
