A high degree of flame retardancy underlay

Designed for IMO boats and ships, Flamecheck 6 contains ATH which breaks down under heat to form water, giving the underlay a self-extinguishing property.

6mm Thickness

International Maritime
Organisation (IMO) approved.

Flamecheck 6 is a lightweight latex foam carpet underlay with all the underfoot and noise-reduction properties of a quality underlay. With the inclusion of specialist additives, Flamecheck 6 also achieves a high degree of flame retardancy to stringent IMO standards and many other fire approval certificates.

Recommended for maritime vessels and offshore installations. Suitable for flame retardant applications and for double-stick and stretch-fit installation of carpets.

Density

Why is density important?

The density represents how much foam is packed into each cubic metre of underlay. A high-value density will indicate a better quality underlay (more foam, less air!). As a rule, the higher these numbers, the more luxurious and supportive the carpet underlay will feel. The higher the density, the longer the life of the carpet.

Acoustic Performance

Does underlay help with noise transfer?

An acoustic or sound rating is used to judge and limit how noise travels within an environment. A Dunlop Underlay can help reduce noise by up to 62%.

Your Dunlop underlay is graded by the AAAC (Association of Australasian Acoustical Consultants) star ratings:
= less than 65dB
= less than 55 dB
= less than 50 dB
= less than 45 dB
= less than 40 dB

Thermal Insulation

What is an underlay thermal rating?

Thermal insulation is measured by an 'R-value' which stands for resistance. Resistance is measured by the amount of heat that passes through a product at a particular time and thickness. The higher the R-value, the greater the insulating power. A Dunlop Underlay can act as a barrier between the subfloor and your hard flooring or carpet. A good thermal-resistant underlay will help keep your energy bills down!

Water Vapour Resistance

What is water vapour resistance?

Water vapour resistance is the measure of a material’s reluctance to let water vapour pass through, taking into account the material’s thickness. The Sd value represents the material’s resistance to movement of water vapour. Hence, the higher the Sd value, the more impermeable the underlay is to water vapour.

* The minimum requirement as set by the NCC is 62 dB (the lower the dB result for the flooring assembly, the better the acoustic performance).
** To achieve the rating of 196 Sd, for Dunlop Advantage 3, the product must be installed with a 200 micron plastic sheet.
*** Thermal resistance is a measure of a material’s ability to resist heat transfer. The higher the R-value, the better heat transfer resistance of that material.
