The isocheck Re-Cork 3 and Re-Cork 5 systems are designed to reduce impact sound transmission through concrete floor decks with a carpet flooring finish.

Re-Cork 3 is a 3mm underlay and Isocheck Re-Cork 5 is a 5mm underlay - both are 100% natural and sustainable products which are highly durable and have long-term resilience.

As well as offering impact noise insulation, Re-Cork 3 and Re-Cork 5 underlays increase carpet durability and enhance walking comfort.

Re-Cork 3 & Re-Cork 5 include all the characteristics of natural cork - it does not compact, it retains its insulating characteristics, does not absorb water, does not rot and resists condensation and mould.


To be used as a carpet underlay over concrete subfloors for conversions, refurbishments or new build. A heated floor system can also be installed beneath Re-Cork 3 & Re-Cork 5.

Performance (on the constructions illustrated)

Laboratory performance achieved 24dB ΔLw for Re-Cork 3 and 33dB ΔLw for Re-Cork 5.
