Underlay for SPC-Lux Flooring

QuietWalk is a fully certified underlayment designed for use alongside SPC-Lux Flooring. It’s also compatible with multiple types of flooring including Laminate, Rigid Core Vinyl (5mm or Thicker), LVT (5mm or Thicker), and Floating Engineered Wood. QuietWalk is supplied in rolls that are 0.929 x 10m, it’s also only 3.175mm thick.

It’s approved for use with underfloor heating systems and allows heat to permeate evenly while protecting the SPC-Lux flooring from thermal shock. QuietWalk is made up of recycled filaments that are specifically designed to cushion the floor, absorb sound, and reduce unwanted noise. It can be used above both concrete and wooden subfloors.

QuietWalk Vapour Barrier

QuietWalk acts as a vapour barrier by attacking subfloor moisture and protecting your SPC-Lux Flooring. It disperses moisture throughout the pad to draw it up and away. This process uses DriWick Technology which promotes moisture dissipation and allows it to evaporate.

QuietWalk Recycled Filament Fibers

QuietWalk is firm but it’s also flexible enough to form around any subfloor imperfections. The recycled filament fibers help support the SPC-Lux UNILINC click mechanism and will withstand continuous heavy footfall.

QuietWalk Sound 

The construction of its fibers allows QuietWalk to absorb sound. This helps to reduce unwanted transmitted noise.

What is the difference between QuietWalk and EcoTec Floor-Foam Insulation?

QuietWalk has been specifically designed for anyone looking to install underfloor heating systems alongside SPC-Lux Flooring. Quietwalk allows the heat to permeate through the flooring into the room above. It also protects SPC-Lux flooring from thermal shock – this is why it’s fully approved for this application.

EcoTec Floor-Foam is an amazing option for anyone that’s not installing an underfloor heating system. EcoTec Floor-Foam prevents cold bridging from below into the room above, it ats as a barrier from exterior temperatures. It improves energy retention and can even help you save on your energy bills.

Which Underlayment Should You Choose?

If you are installing underfloor heating you should install our QuietWalk Underlayment. If you do not intend to install underfloor heating, you should use EcoTec Floor Foam Insulation.

Why would you choose EcoTec Floor Foam over QuietWalk?

EcoTec Floor Foam Insulation acts as a barrier between your home and the external temperature. It prevents cold bridging from below into the room above. At the same time, it improves your energy retention, rather than allowing it to escape.

Why would you choose QuietWalk over EcoTec Floor Foam?

For those of you who have installed or plan to install underfloor heating – you want to feel the benefits opposed to blocking the heat, so you need an underlay that allows the heat to pass through the underlay - which is Quietwalk.
