10mm Rubber EQ1012

Indicative 5 Star AAAC (based on previous testing, actual outcome depends on entire flooring system). Average reduction (delta △) of 10.5 dB on Lntw scale when underlay is installed with various flooring options between 8 - 15mm, compared to original Bare Concrete Floor (ECFS).Why does thicker and more expensive rubber underlay perform worse than foam? Good question - only in initial testing! Foam is an incredible sound absorber when first installed with lightweight floorboards. However, due to it's softer structure, it flattens very quickly once flooring and furniture is installed. Quite quickly, a 2mm underlay can become 1mm in thickness, and with heavy furniture or foot-traffic, it could even compress to 0.5mm in thickness, making it virtually ineffective. However, rubber is much stronger and a quality rubber (not overly recycled) will bounce back and maintain it's structural integrity over time!
