Platinum Premium Shield insulation is designed to make every Platinum Spas hot tub more energy efficient, reliable, and cost-effective. With innovation at the core of our brand values, we are constantly refining our products based on customer insight and industry best practice. One area we never compromise on is insulation, because how well a hot tub retains heat directly affects energy costs, performance, and long-term reliability.

For inspiration, we looked at how modern homes are insulated. A hot tub is no different; it deserves the same level of care and efficiency. That’s why we developed the Platinum Premium Shield insulation system, featured on our Premium range, the newly improved Deluxe range, and our swim spas.

Why Insulation Matters in a Hot Tub

Hot tubs are designed for relaxation and recovery, but they also need to perform efficiently all year round. Insulation is what makes the difference between a spa that costs more to run and one that stays warm for less. According to the Energy Saving Trust, insulation is one of the most effective ways to reduce household energy costs, and the same principle applies to hot tubs.

By reducing heat loss, your spa consumes less energy, works smarter instead of harder, and remains ready whenever you are.

5 Layers of Platinum Premium Shield Insulation

Our Superior Heatlock Insulation Process (SHIP) combines five advanced methods to keep the heat inside the spa where it belongs:

  1. Reflective foil base wrap to minimise ground heat loss
  2. Thick foil-coated panels lining the cabinet for an additional thermal barrier
  3. Multi-layer spray foam on the shell for maximum efficiency
  4. 360° reflective foil wall around the steel structure, recycling warmth and locking in heat
  5. High-quality insulated cover to prevent heat escaping at the surface

Together, these layers create a high-performance thermal system that lowers running costs and keeps water at the perfect temperature all year round.

How It Differs From Standard Foam Insulation

Many hot tubs are built with full-foam insulation. While this method offers some heat retention, it can create challenges:

  • Servicing and maintenance become more difficult, as pipework and pumps are encased in solid foam, requiring time-consuming removal for even simple repairs
  • Pipe movement and vibration from pumps can put pressure on joints over time, increasing the risk of leaks
  • Sound suppression can make the spa quieter, but not in a good way. It reduces the natural ambience of water movement and jet flow that many owners enjoy

The Platinum Premium Shield Advantage

With Platinum Premium Shield insulation, we take a more balanced approach. Our system is:

  • Efficient: retaining maximum heat without overworking pumps or heaters
  • Service-friendly: keeping components accessible for faster, easier maintenance
  • Durable: reducing stress on pipework and fittings by allowing natural movement
  • Immersive: preserving the sound and feel of powerful jet performance without unnecessary suppression

This balanced approach means you enjoy the benefits of superior energy efficiency without compromising on performance, sound, or serviceability.
