Oct 2011. After the adjustment, thank you, the cover is great, and really keeps the heat in overnight A morning swim is now a pleasure rather than a shock! Your estimate of 4-5ºC was on the low side!. No problems to report. HJ V.Milho

May 2011 Thank You Alistair, cover is working well, and the temperatures are higher than expected. No problems so far. Lets see if it lasts 8 years! R.S Paderne

22 July 2011 Just to note to say all is working 100%. Your plunge tiles are all still in place and we are having to add cold water to swim in the pool, the water is so hot! A big thank you. You can consider us PoolSafe disciples. D.C Vale Telheiro

Does your old cover look like this? Fix it for 8 years !

Classic 'striping' due to UV damage of the cover on the roll - without UV protector sheet being used.

These covers are marginally more expensive than the standard bubble covers in use, however the annual cost is considerably less ( roughly half ), in the long run, as their expected life is almost double that of the normal covers. The manufacturer warranties the life for 8 years, and he has told me that he expects 10 years out of a properly maintained cover and pool ( iethe rolled up bubble sheet to be covered when not in use, and with normal Ph and chlorine levels).

500 micron pool bubble covers have been an ongoing problem for me as a house manager, I have been fitting roller covers now for over twenty years in my own and managed properties, and have always wondered why someone didn't produce a cover that lasted more than three or four seasons, even when properly stored and covered.... The bubbles rot, and then come off the bottom, see the cover on the left, with classic rotted 'stripes' caused by being rolled up without a cover. Now I think I have found one that is so much better!

The new ultradome 500 micron cover has been designed to have an even thickness of plastic throughout, eliminating those annoying little disks which pop off the bubbles after a few seasons, even when the cover is properly stored. It is also designed for Australian High UV levels, whereas many of the UK blankets are not.

The manufacturer warranties 8 years on this cover , and when I contacted them about the UV in the Algarve, has told me that in Western Australia where they were tested and produced, the UV is even higher than here. On checking, he is correct.He also told me that the reason that the covers here, start to split off the top of the bubbles, is due to the manufacturing process and thin 'corner' sections.. see the diagram above of 'old' and 'new' ....makes sense doesn't it!

Also the main reason the plastic eventually becomes brittle and breaks, is not just the UV, but the chlorine build up under the blanket.. see more details below...

Why does my cover disintegrate after only three or four seasons?

The impact of Chlorine
Pool chemicals - although essential for sanitation - are highly corrosive.
Whether you have a salt water pool or not - any pool that is chemically sanitised uses Chlorine as the disinfectant.
Molecular Chlorine (Cl2) is a highly corrosive greenish-yellow gas with an irritating odour.
In whatever form Chlorine is added to the water, or produced by a salt water chlorinator - it eventually returns to its natural state as a gas and escapes.
However, when a pool cover is in use it cannot simply disperse into the atmosphere. It is trapped immediately below the blanket. This area is also heated t by the sun - increasing Chlorine transfer from the water - at a high temperature.

These factors combine to create extreme conditions that are likely to increase blanket degradation.
Dome Solar Pool Blankets combat potential degradation in the following ways:
• Dome bubble profile creates an even, thicker bottom layer with no weak points
• Dome material contains maximum UV absorbers, quenchers and stabilisers
• Dome material also contains tougheners to minimise the effect of solar and chemical degradation
How do Dome blankets insulate against heat loss?
The Dome bubble profile results in a total insulating air layer to almost the entire bubble depth.
