FINIXPE underlay

FINIXPE underlay

The next generation of “Floating Floor” underlay is now here, FINIXPE underlay.

We are all familiar with this underfloor system which has been used on both our Sapphire and Diamond Core ranges, however, we are all aware of why we, FINfloor, chose to go this route as opposed to buying a less costly system like EVA.

What is IXPE?

IXPE is a premium acoustical underlay made up of sound dampening high performance cross-linked foam, with an overlapping vapour barrier of 80 micron HDPE (High Density Polyethylene), for extra moisture protection at the joints.

The extra fine foam manufacturing technology offers advanced moisture protection, stops any impurities leeching from the screed and through the joints into the floor above and at the same time the underlay acts as a shock absorber. This is achieved by using PFT (Progressive Foam Technology), which is designed to contribute to supreme sound suppression/reduction.

The material in itself is totally non-toxic and odourless and does not contain any toxic auxiliary agents in the make-up.

FINIXPE underlay (Irradiated Cross-Linked Polyethylene) is resistant against mold & mildew, with excellent Anti-crush technology for better performance over a greater life span, with very good memory retention, which will contribute to the continued performance of your floor over many years of use.

Why do we need to use an underlay, besides having that comfy feeling underfoot?

The underlay is a necessary barrier between your floor and the sub-strait below. It prevents anything from coming through from the bottom up into the floor, making your home healthier, safer and quieter.

Not only does the underlay contribute to the points above, the IXPE also acts as an excellent insulator, it is also a great contributor to improved sound control, based on the IIC (Impact Insulation Class) rating, with results of 59-60 db, specifically referring to impact sound, such as footsteps, this being one of the main elements that a good underlay can control.

Airborne sound, e.g. loud music is rated using a different metric called STC and in almost all cases requires a suspended ceiling to mitigate against this type of sound.

Due to the use of the Irradiated Cross-linked Polyethylene the product is a closed cell foam which makes this 100% waterproof and impervious to rot, mildew, mold and bacteria.

This IXPE technology has been used with great success in the automotive, medical and hospitality industries for some years.

In many instances it is very likely that the interior of your vehicle relies heavily on IXPE to keep the cabin insulated, both in terms of sound but also temperature.

Once again FINfloor raises the bar in breaking down the barriers, to improve our users living spaces.
