thrml.™ PLANET PLEDGE

At thrml.™, we believe that wellness should never come at the expense of our planet. Traditional hot tub covers, often built with expanded polystyrene (EPS) foam—commonly known as Styrofoam—pose significant environmental challenges. These materials absorb water over time, leading to rapid degradation, reduced insulation performance, and premature disposal. Once waterlogged and moldy, they contribute to landfill waste that persists for centuries, release microplastics and persistent pollutants, and have a high global warming potential due to production processes involving harmful blowing agents and chemicals like styrene (a classified carcinogen in some regions). Millions of these covers end up in landfills annually, exacerbating pollution, resource depletion, and climate impact.

 

We founded thrml. to change this. Our commitment is to design and deliver hot tub covers that are earth-conscious from core to cover—starting with the revolutionary AIRCAP 1™ and extending to every future product and packaging solution.

 

We Pledge to:

​

1. Prioritize Superior, Sustainable Insulation

Engineer the AIRCAP 1™ and all thrml.™ covers with advanced, high-performance insulation alternatives that capture and retain heat far more effectively than traditional foam, drastically reducing energy use for heating hot tubs and lowering carbon emissions for every user.

 

2. Eliminate Harmful Materials

 

Avoid polystyrene (EPS/Styrofoam), high-GWP blowing agents, and other persistent pollutants. Instead, we select durable, low-impact core materials designed for longevity, minimal water absorption, and reduced environmental footprint throughout their lifecycle.

 

3. Maximize Durability and Longevity

Build hot tub covers and products that last significantly longer—resisting UV degradation, moisture intrusion, and wear—so fewer replacements are needed, cutting waste and the demand for new resources.

 

4. Conserve Resources at Every Step

Minimize evaporation to save water, reduce chemical treatments through better heat and cleanliness retention, and promote energy-efficient hot tub ownership that aligns with global sustainability goals.

Deliver Zero-Plastic, Fully Recyclable Packaging. Use only recyclable, plastic-free materials—such as high-recycled-content corrugated cardboard, kraft paper, and sustainable adhesives—for all packaging. This ensures our products arrive with zero single-use plastic waste and can be easily recycled curbside in most communities.

 

5. Foster a Circular Future

Design for reparability, recyclability, and end-of-life responsibility, encouraging a shift away from disposable covers toward products that support planetary health for generations to come.

 

thrml.™ is more than a brand—it's a promise. By choosing the AIRCAP 1™ or any thrml.™ product, you're joining us in redefining hot tub wellness: luxurious, efficient, and truly earth-conscious. Together, we can make relaxation a force for good.
