Cork Underlay

Insulate and protect your home the natural way with a cork underlay. Cork underlayment has special properties that prevent it from wearing away. Meaning it will last and protect your flooring over long periods of time.

Cork is the perfect option as an underlay for wooden floors and panels. It acts as a great insulator, helping to keep a room warm. It’s also a great material for isolating acoustics — helping to keep out unwanted sounds. Cork is also shock-absorbing, and very comfortable to walk over. A quality that may help with the prevention, and quick recovery of, feet, joint and back problems.

A cork underlay is also very safe. Laid down on the ground, it efficiently smoothes over small faults on any surface. Making it easier to install flooring over it, along with making the ground more level. Cork underlayment is also naturally fire resistant and, even when burned, doesn’t release any toxic gases.

Cork underlay benefits

  • Nature’s insulator — Cork is naturally warm to touch and is a brilliant insulator by composition. As a substance cork is made up of millions of cells that are full of air. It is these cells that absorb and guard against the cold, noise, moisture and vibrations.

  • Beats the competition hands down — Unlike form and porous wood and fibre underlayments, cork does not lose its thickness over time. Cork does not deform. If it is exposed to pressure, it will return to its natural shape once that pressure is lifted.

  • Hypoallergenic and anti static — Cork doesn’t attract or absorb dust, making it ideal for anyone suffering from asthma or allergies. As a material, it also resists electrical charges near the surface. Meaning it is also anti static.

  • Incredibly light and damage resistant — Cork is almost entirely made up of air. In fact, cork is up to five times lighter than water. This unique quality also makes it almost impervious to damage. As the cell-structure diffuses force from any impact to it. Cork underlay is also abrasion-resistant.

  • Sustainable and environmentally friendly — Cork grows so fast, it is essentially a renewable, green material. It can be extracted without ever damaging the tree that it comes from. And cork is all 100% natural and recyclable.

1. Is cork underlayment the best?

Cork absorbs sound a lot better than most other underlayment materials. It’s also eco-friendly, does not collect or absorb dust and grime, and works as a brilliant insulator too. In most circumstances, it is the ideal underlay. However cork is not waterproof (though it is water resistant). In areas that are prone to water getting on the floor, such as in bathrooms, it may be better to use a rubber underlay instead.

2. Does cork underlayment need to be glued down?

No. Underlayment in general is a floating material a bit like laminate flooring. You aren’t supposed to glue or nail down your cork underlayment.

3. Is cork underlay waterproof?

No. But it is naturally water resistant. Cork is also mold and mildew resistant. Making it the ideal choice for most rooms and environments. But perhaps not for areas that are exposed to excessive moisture, such as bathrooms.

4. Can you glue engineered hardwood to cork underlayment?

Yes. A general rule of thumb is, treat your underlay like you treat your floor. So if you want a floating top floor, then don’t glue your underlay down. And if you want a glued down floor, then glue down the underlay. Our cork underlays accept any type of water-based construction adhesive.
