How do I take care of a thermal cover and extend its lifespan?

Correct care and storage is important for the longevity of your thermal pool cover. Click here to download a guide on how to care for your cover and extend its lifespan. Please also see our Covers for Covers range of tailored covers for different products.

Handling of thermal pool covers

Always handle thermal pool covers with care and avoid scraping the bubble surface on or over any obstacles.


Please note that the thermal cover is designed as an insulating cover and not as a child or pet safety cover. It must be completely removed from the pool before swimming and under no circumstances should anyone stand, sit or jump on the cover. Never swim with a thermal cover on the pool or when the pool is partially covered.

Rollup Stations

Deploying the thermal cover: when pulling the cover over the water, ensure that the Rollup Station is secure, otherwise it may be pulled into the pool. If you have a Rollup Station, protect the handle and do not pick up the station by the handle but rather use the neck area when carrying. Do not allow adults and children to sit on the Rollup Station.

Leading Edge

Focus on protecting the light blue reinforcing as it is in this area that covers take the biggest abuse! Check that the C-clamps are in place and secured tightly by the fitted white nylon bolts and washers. Check regularly and tighten when necessary. Replace lost or missing components immediately, as the cover will wear faster without them. The guide rope on the leading edge should be long enough to enable the user to walk around the pool and once opposite the cover, pull the cover closed. Ensure that there is sufficient length. Use the rope to secure the cover when not in use by winding the rope around the cover. Secure neatly. Never let the reinforcing on the leading edge hang on the ground.

Attachment Kit

The cover is secured to the Rollup Station with an attachment kit. Check that all blue toggles are in place and on the cover. Replace when required. Check attachment kits regularly. Ensure that there are no sharp objects affecting the cover. Roll up in a clockwise direction. This will enable the cover to lie flat on the Rollup Station.


Always cover the thermal blanket with the UV protection sheet provided when not on the pool. This will ensure a longer life span for the thermal cover.


While wind protection devices can be added to a cover, the cover must be removed from the water when the winds rise above 65km/h.


Ensure that the pool salt levels and pH etc. are all within recommended limits. In the event of a harsh chemical treatment, remove the thermal cover from the pool for a couple of days. Chlorine, when added to pool water, automatically reverts back to its gaseous state (a gas) and dissipates into the atmosphere though evaporation. When a cover is on the pool, evaporation is dramatically reduced which can lead to a chlorine build up. To avoid a higher concentration of chlorine, the level and input of chlorine must be reduced.

What is shrinkage and how do I counteract this?

When thermal bubble covers first came onto the market, there was limited technology invested in the actual bubble and the material was relatively predictable in terms of how it reacted when in the pool environment, but their performance and longevity was nothing like our GeoBubble covers of today. As materials have become more durable, have greater UV stabilisation and are so much more sophisticated in their unique performance, thermal bubble materials have become susceptible to shrinkage. It is agreed in the industry that the heightened performance and longevity of “next generation” bubble covers like GeoBubble far outweigh the shrinkage issue, as the shrinkage can very easily be addressed by simply adding a small percentage to the length of the cover. Shrinkage will not always occur but certain factors increase the likelihood of this, including over-use of chemicals. As such, to accommodate the small chance of shrinkage, we strongly recommend all GeoBubble covers are ordered at 2% longer on the length measurement (width can be exact). Click here for a guide on how to do this measurement. This extra length can easily be tucked under and therefore not visible when the pool is covered. You may of course order your exact length but please check warranty terms and conditions before purchasing because if shrinkage occurs you may not be able to rectify this under your warranty terms.  It is not our policy to add material to accommodate shrinkage after it happens. This applies to EnergyGuard, Sol+Guard and Thermal GeoBubble covers only.
