With our planet increasingly impacted by resource shortages, conservation has become a global priority. Since 1950, Enbi has developed insulation solutions that make a positive contribution to protecting scarce resources, and our EnbiTherm storage tank insulations play a unique role in this mission.
The European community is leading the world with rigorous environmental regulations for heating systems and insulation capabilities. In some water tanks associated with heating systems, new energy certification and labels are mandatory (e.g. label “B” for a tank up to 500 liters / 132 US gal). These optimized insulations are contributing to a better environmental balance and providing cost savings to residential and commercial customers.
Customized and lightweight, EnbiTherm gives you the freedom to design innovative systems to provide end user benefits such as reduced energy costs, a reduced carbon footprint and better space utilization.
What is a storage tank insulation?
Our storage tank insulation systems – crafted as custom-fit protective covers – are designed to wrap seamlessly around water cylinders or buffer storage tanks. Engineered for industrial-grade energy efficiency and cost-effective thermal performance, they help maintain water temperature and significantly minimize heat loss.
Constructed from high-quality materials such as PET fibre and flexible foams, our insulations are available in various sizes and thicknesses to suit diverse tank types. Each unit is equipped with heavy-duty fixings, a flame-retardant outer cover, and customized apertures to accommodate inlets and outlets – ensuring easy installation and system compatibility.
To elevate performance, we also offer pre-engineered, modular wrap solutions that incorporate vapor barrier technology and fire-resistant layers. These advanced features not only reduce CO₂ emissions, but also enhance operational reliability – helping you save on heating costs while minimizing your carbon footprint.
How to choose the right storage tank insulation?
Choosing the right storage tank insulation is essential for maximizing energy efficiency, achieving cost savings, and ensuring long-term performance. Here are the key considerations to guide your selection:
Material & Thermal Performance
Enbi’s insulations utilize a combination of EPS (Expanded Polystyrene) and PET fleece, capped with a durable high-impact PS cover – materials specifically endorsed by Enbi for their systems. EPS delivers excellent thermal insulation, is lightweight, moisture-resistant, and easy to install. PET fleece adds enhanced thermal retention, flexibility, and sound-dampening properties.
Size, Thickness & Tank Fit
Ensure the insulation matches your tank’s dimensions. Enbi offers customizable shapes and precise sizing to accommodate different cylinder types and support the necessary thermal resistance (e.g., EnbiLinea and EnbiTrapezio)
Fire Safety & Flame-Retardant Protection
A flame-retardant cover is critical for fire safety – helping prevent ignition and protecting the system in high-temperature environments. Enbi’s B1-rated PS sheet coatings follow stringent fire standards like DIN 4102‑1.
Durability & Fastening Options
Look for robust heavy-duty fixings and high tensile strength materials to ensure the insulation remains securely attached and maintains its integrity over time. Enbi’s insulation jackets include such features for reliable performance.
Return on Investment & Sustainability
While upfront costs vary, the long-term energy savings and reduced heating demand yield a strong ROI- especially in commercial environments like hospitals or multi-dwelling residences. The inclusion of recycled PET fleece also contributes to eco-friendly credentials, lowering your project’s carbon footprint
Expert Support & Tailored Advice
Enbi’s engineering team can guide you through the selection – helping align material choice, thermal ratings, and installation method with your specific system needs.
Is a Flame-Retardant Cover Necessary?
Yes. A flame-retardant outer layer is more than just a bonus – it’s a vital safety feature. Enbi’s PS sheet covers are rated B1 according to DIN 4102‑1, offering essential protection against fire hazards and ensuring compliance with safety standards.
By selecting insulation built with EPS, PET fleece, and high-impact PS cover, and ensuring proper sizing, secure installation, and fire safety, you’ll optimize performance, safety, thermal retention, and longevity – all while supporting sustainability.

Installing a storage tank insulation can provide numerous benefits for users and operators. The main advantage is reducing heat loss from the storage tank. Adding Enbi’s insulation retains heat within the tank for longer periods, resulting in less heat being wasted and a more efficient heating system.
Improved energy efficiency is another significant benefit of the storage tank insulation. With less heat loss, the water heater doesn’t have to work as hard to maintain the desired temperature, leading to lower energy consumption and a reduced electricity bill.
By keeping hot water warmer for longer, the insulation ensures that users have a readily available hot water supply whenever needed. This can be particularly beneficial for large households or during periods of high demand.
