Experience Superior Insulation with ThrmlTech

The future of Hot Tub Covers; Why Insulation Matters

Traditional hot tub covers often fall short when it comes to retaining heat. Over time, foam cores absorb water, become heavy, and lose their insulating power—leading to higher energy bills and longer wait times for your next soak.

​

ThrmlTech’s AIRCAP cover changes the game. Engineered with advanced drop stitch technology, AIRCAP delivers unmatched insulation, keeping your hot tub hotter for longer and your energy costs lower.

How AIRCAP Outperforms Traditional Covers

1. Maximum Heat Retention

  • Drop Stitch Construction: Unlike foam, our high-pressure woven core resists waterlogging and maintains its insulating properties for years.

  • All-Weather Performance: AIRCAP’s airtight design forms a superior thermal barrier, minimizing heat loss even in harsh climates.

2. Faster Heat-up Times

  • Efficient Insulation: Less heat escapes, so your hot tub reaches your desired temperature faster—meaning less waiting and more relaxing.

  • Consistent Warmth: Enjoy spontaneous soaks without the frustration of lukewarm water.

3. Lifetime Energy Savings

  • Lower Utility Bills: By reducing heat loss, AIRCAP can cut your hot tub’s energy consumption by up to 30%* compared to aging foam covers.

  • Long-Term Value: Traditional covers degrade quickly, requiring frequent (and costly) replacements. AIRCAP’s durable design means fewer replacements and more savings over the life of your spa.
