FAQ
What is thermal foil and how does it work?+
Thermal foil is a highly reflective material designed to minimize heat transfer. In a pool cover context, it reflects radiant heat back into the pool, reducing the amount of heat lost through evaporation and maintaining warmer water temperatures for longer.
Is this cover suitable for saltwater pools?+
Yes, this thermal foil is compatible with both freshwater and saltwater pools. The material’s inherent properties are unaffected by the mineral content present in saltwater environments.
How effective is it at reducing evaporation?+
The reflective nature of the thermal foil significantly reduces surface evaporation. This helps to conserve water, lowering your pool chemical usage and associated costs.
What kind of debris does this cover effectively prevent?+
This cover excels at preventing large debris like leaves, twigs, and insects from entering the pool. The tight weave also minimizes smaller particulate matter.
Does it require any special installation?+
Installation is straightforward – simply lay the thermal foil over the water surface and secure the edges with the provided straps. No specialized tools or expertise are needed.
Is this cover suitable for all pool sizes?+
While designed to be adaptable, it’s most effective on pools up to 10m x 5m. Larger pools may require multiple covers for optimal coverage.
How does this compare to a standard PVC pool cover?+
Thermal foil offers superior heat retention compared to traditional PVC covers due to its reflective properties. This translates to lower energy costs and improved water temperature stability.
What cleaning products should I use on the thermal foil?+
Use mild, pH-neutral detergents specifically designed for pool equipment. Avoid abrasive cleaners that could damage the surface’s reflective coating.
How long will this thermal foil last?+
With proper care and maintenance, this thermal foil is expected to have a lifespan of 5-7 years under normal use conditions. Regular cleaning helps prolong its effectiveness.
Can I use this cover when the pool is in use?+
The cover can be used while the pool is in use, but it's important to avoid excessive foot traffic on the surface to prevent potential damage and maintain optimal reflectivity.
