As a leader in the market, our mission is to provide superior support, shock absorption, industry-leading acoustic performance, and moisture barrier underlayment for residential and commercial spaces.

We also focus on sustainable solutions through our Magnus^® flooring line.

Our Range of Premium Solutions

We have you covered, whether you need the best underlayment for floors in a high-traffic living room, a moisture-resistant solution for a basement, or rubber flooring for a gym.

Hardwood, Engineered, and Laminate Underlayment

Laminate and wood floors are naturally resonant and sensitive to environmental changes, making the choice of underlayment vital for long-term performance. Our collection for these flooring types is designed to enhance comfort, durability, and overall floor performance. Acoustically, these products deliver strong Impact Insulation Class (IIC), Sound Transmission Class (STC), and Delta IIC ratings, helping reduce footfall noise and limit sound transfer between rooms and levels. Many options also include advanced moisture management technology that helps protect against vapor from concrete subfloors while still allowing the floor system to breathe, helping prevent issues like warping or damage over time. Select products feature our built-in ultraSeal lip and tape system, which streamlines installation by allowing adjoining underlayment sections to be easily connected, eliminating the need for additional tape. Whether you’re looking for an environmentally friendly solution or an underlayment with a higher R-value for added warmth, our team can help you find the right fit. This category includes high-performance options for both laminate and hardwood flooring applications. Options include:

floorMuffler^® ultraSeal: Offers high acoustic ratings, 74 IIC / 73 STC, for noise isolation and moisture protection (0.3 lbs MVTR).
quietCure^™ ultraSeal: Provides a reliable professional-grade balance of acoustics (71 IIC) and features a higher R-Value of 4.0 for enhanced thermal insulation, making it a cost-effective choice for contractors.
comboFoam® underlayment: Made of our polyethylene foam, it levels some minor subfloor imperfections and provides standard moisture protection (2.0 lbs MVTR) for budget-conscious projects.
Natura^™ Elite: An environmentally friendly underlayment for laminate, engineered and hardwood floors, where sustainability is key, this professional-grade product is 3.5mm, and uses 98% recycled fibers to achieve density and support.
floorMuffler^® Flex: Made out of recycled rubber, provides acoustical benefits and can be used under multiple floor types. Options range from 2mm up to 10mm in thickness. This product does not provide a moisture barrier.
FloorMat^® FanFold: Stands out with a unique fan-fold design for rapid large-area coverage and offers a high thermal protection of 5.0.

Luxury Vinyl and Rigid Core Underlayment

Luxury Vinyl Tile (LVT) and Rigid Core planks are thinner and denser than wood, requiring a specialized vinyl flooring underlayment foundation. The primary benefit of this category is high compressive strength, which is essential for supporting the click-lock mechanisms of thin vinyl planks to prevent joint breakage. Our products provide that essential barrier while offering significant acoustic improvements, softening the sharp tapping sound often associated with rigid core floors. Whether you are installing over a concrete slab or a plywood subfloor, these solutions are the best underlayment for vinyl plank flooring, providing stability and comfort underfoot. Explore our options below:

floorMuffler^® Encore: A thin-profile, high-density underlayment engineered for use with pre-attached pad flooring. With compressive strength exceeding 40 psi, it helps protect locking systems while improving acoustics and offering moisture protection.
floorMuffler^® LVT ultraSeal: Provides a thinner 1mm profile with higher acoustic ratings (71 IIC). This underlayment is suitable for luxury vinyl floorings with double-glue down or floating installations.
floorMuffler^® Flex: Made from high-density recycled rubber (60 lbs/ft³), this durable underlayment provides a resilient foundation for a variety of applications. It is compatible with floating and double glue-down installations and requires a separate moisture barrier when moisture protection is needed.

Porcelain and Ceramic Tile Underlayment

Tile floors are rigid, so they require an underlayment that can absorb structural movement to prevent cracking. The key benefit of this underlayment category is its crack-isolation performance. The underlayment acts as a membrane, decoupling the tile from the subfloor and preventing stress cracks from transferring to the finished floor. It also reduces impact noise, which is a common issue with hard ceramic surfaces. floorMuffler^® Flex is the best underlayment for floors made of porcelain or ceramic tile. Available in 2mm, 5mm, and 10mm and suitable for floating and double-glue-down installations, it provides the unique density required to support heavy tile loads while isolating subfloor movement to prevent grout and tile cracking.

Recycled Rubber Floors

Unlike underlayment, which is installed under floors, rubber flooring is the visible surface you walk and work on. Suitable for gyms, fitness rooms, and utility spaces, our recycled rubber products withstand heavy impacts, dropped weights, and high foot traffic while offering superior slip resistance. Our rubber floors are resistant to mold and mildew, making them suitable for basements and garages.

floorMuffler^® FlexLock is a rubber tile system suitable for this category. This product is 8mm and features interlocking tiles for adhesive-free installation on top of the floor for impact absorption.
