Synthetic turf is only as good as what sits between the blades. Infill carries the load. It holds fibers upright, absorbs impact, controls ball roll and bounce, and, more than any other component, shapes how a field feels and how hot it gets. For decades, the default answer was crumb rubber. Today, however, increasing environmental scrutiny, regulatory change, and demand for cooler, more natural playing surfaces are driving the search for alternatives. Among the materials gaining the most attention is cork.

When it comes to flooring systems, most people focus on what they can see: hardwood, tile, vinyl, cork, or laminate flooring. But what lies beneath these finished surfaces can play an equally critical role in long-term performance.

One of the most overlooked factors is vapor permeability.

Cork may be best known for its use in flooring, wall coverings, and closures, but it also plays a role in one of the most demanding engineering environments in the world: spaceflight.

In aerospace, engineered cork-based materials are used as part of thermal protection systems (TPS) - materials designed to protect rockets and spacecraft from extreme temperatures. These systems must withstand both the intense heat generated during launch and the cryogenic cold of stored propellants.

Most people open a bottle of wine and never think twice about the cork. At Jelinek Cork Group, that small stopper represents something bigger: the opportunity to keep a natural, renewable material in use as long as possible. Since 2005, Jelinek Cork Group has been a founding force in North America's natural cork recycling initiative, collecting and repurposing upwards of 100 million corks. What was once destined for landfill is now raw material for a remarkable range of products ranging from handmade home decor to commercial flooring, from schoolroom crafts to large-scale construction.

This guide covers everything you need to know for QuietCork™ Underlayment installation: subfloor preparation, floating and glue-down hardwood installation, perimeter acoustic detailing, and ceramic tile applications.

Cork underlayment is a natural acoustic and insulating layer installed between the structural subfloor and finished flooring to reduce noise, improve comfort, and enhance flooring performance.

Interior design trends continue to shift toward warmth, texture, and genuine sustainability in 2026, with one natural flooring material really standing out: cork. Far from being a throwback choice, today's cork floors represent a modern solution perfectly aligned with how we want to live. Cork flooring prioritizes comfort, environmental responsibility, and a sensory connection to nature.

As we move deeper into 2026, the interior design world is witnessing a remarkable shift toward sustainable, eco-friendly materials that don't compromise on style or performance. Leading this green revolution is an age-old material that's experiencing a modern renaissance: cork wall tiles. At Jelinek Cork Group, with over 170 years of expertise in cork manufacturing, we've seen firsthand how cork wall coverings are transforming residential and commercial spaces across North America.

As construction professionals and homeowners search for ways to reduce their environmental impact, one natural material is experiencing a remarkable comeback. Cork insulation, which has been used for centuries in cold storage, is now leading the charge in carbon-negative building practices. As the construction industry accounts for a substantial portion of global carbon emissions, moving toward materials that actively sequester carbon instead of emitting it marks a fundamental shift in how we build.
