Accessories for 5mm Custom Cut Rubber Underlayment

Description - Our 5mm custom cut rubber underlayment has been shown to offer the best sound insulation in the market. 5mm rubber underlayment has been shown to outperform all leading forms of underlayment including 12mm cork and 12mm foam. Our custom cut rubber underlayment allows anyone to custom cut the length of the roll to the nearest whole foot increment. This allows for less waste and also allows for an easier install with less cutting. Rubber is great to use in areas that are at and above grade and is great in areas where water may be present. If water is present, then it would be required to use a vapor barrier to protect your floor. This sound proofing underlayment is also mold and mildew resistant which is due to the fact that rubber does not hold water. This flooring underlayment also does not have to be adhered to the flooring substrate, but can be stapled, nailed or taped down. This is also good for floating floors.
