The new Heat Retention Hot Tub Cover, RaeGuard™ is engineered specifically to maximise heat retention through carefully tailored reflective properties. Maximize Thermal Efficiency Crafted with precision, the silver and white layers of RaeGuard™ feature carefully chosen pigments engineered to effectively reflect and scatter radiative heat, optimizing thermal energy retention within the targeted mid-infrared spectrum. Enhanced Heat Preservation Equipped with the innovative GeoBubble™ air cell technology, this Heat Retention Cover forms a robust barrier, effectively curbing the dissipation of thermal energy from the hot tub or swimming pool surface. Effective Evaporation Management By using a cover such as this, the loss of thermal energy through evaporation is mitigated, helping your hot tub maintains its warmth without expending energy to transform into vapor. Protection As well as the energy saving effects listed above, the Raeguard™ Floating Cover also serves as an additional safeguard, shielding against chemical degradation of the underside of the hot tub cover and safeguarding pillows and controls above the waterline.
