  • Screed underlays

    What’s better than coming home after a busy day and just enjoying the silence?
    Silence can make us drift away and relax.

    For years, Abriso Jiffy has invested in the research of screed underlays, measuring how this material can reduce impact sound.

Abriso Jiffy, a strong partner
in screed underlays

Contact sounds are created by sound vibrations transmitted through structures of a building to other spaces. For example footsteps, objects falling to the ground or moving chairs.

To reduce the effect of contact sounds, contractors and architects work with a floating screed which is placed on top of an acoustic underlay with side strips. This way, the screed is never in contact with the underlying filling layer and the vibrations are absorbed by the acoustic underlay and side strips.

KNOCK, KNOCK, KNOCKIN’ ON NEIGHBOUR’S DOOR

If you want peace and quiet to be enjoyed in your building, then installing the right screed underlay is a must.
Many underestimate the impact of contact sound. After all, nobody likes to be woken up by a falling object on the floor above. Or to be disturbed during a conversation or television programme by the footsteps of an upstairs neighbour.
Studies by various acoustic agencies show that the correct installation of a floating screed is vital for a higher and more performant dB improvement index.
So, Abriso Jiffy offers not only screed underlays but also a variety of Acoustic Side Strips. These allow architects and contractors to discover the optimal solution for every construction project.

Product adapted to your needs:

  • The Acoustic Abrifiber® 9 mm is a 3-part acoustic underlay that provides ultimate sound reduction of impact noise between building floors. Thanks to its unique 3-part building-up, including a felt layer, this product easily overachieves on the strictest requirements of the current standard NBN S01-400-1 for residential buildings.

    The 50mm overlap ensures full acoustic damping. The Acoustic Abrifiber® 9 mm achieves an improvement index of 36dB with a foam concrete infill layer and 33dB with a Betopor infill layer.

    Unlike many other underlays, it is suitable for floor heating.

    Last but not least, the Acoustic Abrifiber® 9 mm can be perforated without acoustic consequences, when installing floor heating.

    Properties:

    • Ultimate acoustic damping up to 36dB
    • Can be perforated for use of floor heating
    • Overlap for full coverage
    • Meets the most stringent requirements
    • Easy to install
    • Tested by Buildwise (WTCB)
  • The Acoustic Abrifiber® 7 mm is a 3-piece acoustic underlay that provides the ultimate in contact sound reduction.

    The felt layer of this product is the extra added value. This bottom layer provides ultimate sound vibration absorption. This underlay is easy to install and process. Use this product with a floating screed to achieve maximum and effective sound absorption. Sufficient attention should always be paid to the 100 mm overlap.

    Thanks to the careful composition of its 3 layers, it achieves an improvement index of 35dB for a foam concrete infill layer and 32dB for an insulation mortar infill layer.
    Acoustic Abrifiber 7® mm scores particularly high within the current standard NBN S01-400-1 for residential buildings.

    Properties:

    • Ultimate acoustic reduction up to 35dB
    • Overlap for full coverage
    • Meets the most stringent requirements
    • Easy to install and process
    • Tested by Buildwise (WTCB)
  • This screed underlay is an extruded polyethylene foam (PE) composed of 4 laminated layers of 2 mm (alternating green/white) in a density of 25 kg/m3.
    This achieves a value of 27dB.

    Thanks to the printed top with cutting lines, you can proceed carefully for optimal installation. The Acoustic Foam® 4x2 mm has an overlap of 100 mm. It can be used in combination with floor heating. As the underlay cannot be perforated, it is advisable to lay the floor heating pipes in a flexible structured floating membrane.

    Properties:

    • Acoustic reduction (27dB)
    • Printing with cutting lines
    • Budget-friendly
    • Overlap for full coverage
    • Light and easy to process
    • 100% recyclable
    • Tested by Buildwise (WTCB)
  • The Acoustic Reflex® 2x3 mm has a thickness of 6 mm consisting of 2 laminated layers of extruded polyethylene foam (grey at the bottom and white at the top) of 3 mm each in a density of 35 kg/m3 and printed with the brand name ACOUSTIC REFLEX®.

    When the height of the infill layer or screed is rather limited, Acoustic Reflex® 2x3 mm is the perfect solution. With a thickness of only 6 mm, this budget-friendly alternative achieves a value of up to 23dB. This product also features a 100 mm overlap.

    The material used is rot-proof and resistant to moisture, water vapour and has a high chemical resistance. This product can also be used in combination with floor heating. As the underlay cannot be perforated, it is advisable to lay the floor heating pipes in a flexible structured floating membrane.

    Properties:

    • Acoustic reduction (23dB)
    • Limited thickness
    • Budget-friendly
    • Overlap for full coverage
    • Light and easy to process
    • 100% recyclable
    • Tested by Buildwise (WTCB)
  • The narrow Acoustic Foam® 5-35 is ideally suited for solid impact sound insulation between load-bearing and floating floors with limited height.
    This product is mainly used if the height of the floor construction is very limited. In such cases, every millimetre counts.

    As this product consists of only 1 layer of 5 mm extruded polyethylene foam (PE), we also offer a solution for these situations. It is possible to use this in combination with underfloor heating. In this case, we recommend installing it on top of the Acoustic Foam® 5-35.

    The underfloor heating pipes are held in a flexible textured membrane intended to be installed floating. The Acoustic Foam® 5-35 should not be punctured during installation.

    Properties:

    • Very limited thickness, only 5 mm
    • Budget-friendly
    • Acoustic reduction (21dB)
    • Light and easy to process
    • 100% recyclable
    • Tested by Buildwise (WTCB)

Making the right connection

Correct installation of acoustic underlays and side strips is very important to achieve the best acoustic results.
Our side strips, Acoustic Strip, should be used for vertical installation against walls.
Acoustic underlays should never be folded up against standing walls. For optimal results, it is important that there are no seams between the connecting layers.
Ask for the installation instructions for this product.

Sustainable & Responsible

In addition to a soundproofing function, screed underlays also have an insulating and thermal function. As we are committed to sustainability, it is important to extend this to our products.
That is why we invest in the production of products that are 100% recyclable. Last year we recovered 15,000 tonnes of waste and saved more than 25,000 tonnes of CO2.
With Abriso Jiffy’s screed underlays and Acoustic Side strips, you are helping to create a sustainable building in a sustainable world.
