Isocheck Impact Mat 100, 200 & 300

Impact and airborne improvement systems for timber floors

Isocheck Impact Mat acoustic flooring systems are designed for high levels of impact sound reduction through timber floors and staircases where an acoustic test is accepted for this type of system. (Not all authorities will accept a test on a soft floor covering when laid on a structural timber floor).

Isocheck Impact Mat 100 is a 6.5mm thick layer of Isolate R which will provide impact improvement. Isocheck Impact Mat 300 is a 12mm tri-layer system with an Isopoli core. Impact Mat 200 consists of an 8mm Isofiba / barrier mat composite and can be used as a single or double layer.

When installed and accepted as part of a complete party floor construction all systems enable a timber floor to meet the sound transmission standards of Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 and 2015.

(on the constructions illustrated)

Isocheck Impact Mats 100 & 300 will typically achieve up to 30dB & 40dB ∆Lw respectively in laboratory conditions.

Laboratory performance of Impact Mat 200 achieved 26dB ∆Lw for a single layer. Site test results have also proven favourable performance in relation to Approved Document E requirements, where airborne noise reduction was significantly enhanced, in addition to impact noise reduction.
