Our 4.5mm Acoustic Rubber Underlay is a premium, high-density rubber underlay designed for applications where exceptional sound performance and long-term durability are essential. Suitable for both domestic and commercial projects, this underlay delivers industry-leading acoustic reduction, making spaces quieter, more comfortable and more stable underfoot.

Whether you're refurbishing a flat, upgrading a multi-storey property, insulating hotel rooms or improving soundproofing in busy family homes, this product provides a reliable and professional-grade foundation for laminate, engineered wood and click-system floors.

Its dense rubber structure reduces impact sound transmission and ensures long-lasting compression strength, helping protect your flooring from wear over time while maintaining a solid, stable feel.

Exceptional Acoustic Performance

The 4.5mm acoustic rubber layer offers outstanding impact sound reduction — up to **26dB**, depending on the flooring system. This makes it ideal for:

  • Multi-level homes
  • Apartment buildings
  • Offices & commercial units
  • Hotels & student accommodation

The dense composition absorbs vibrations before they pass through the subfloor, ensuring noticeable improvements in noise control and comfort.

Moisture & Subfloor Protection

A built-in gold vapour barrier helps prevent moisture transfer from the subfloor. When installed with vapour tape, it forms a continuous protective layer, reducing the risk of movement, swelling and long-term damage to the flooring above.

Easy Installation & Professional Reliability

This underlay is designed for installers who require both performance and practicality. It cuts cleanly, lays flat and works perfectly beneath:

  • Engineered wood flooring
  • LVT (floating systems)
  • Laminate flooring
  • Click-system flooring

Its high tensile strength ensures the floor above remains supported, helping prevent hollow spots, creaking and premature board movement.

It also assists with slight subfloor unevenness, helping create a smoother, more stable finish across large areas.

For advice on suitability, installation, subfloor preparation or quantity calculations, our Timberzone team is always available to help.

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.
