Insulating a swimming pool
Obviously popping some polystyrene board down the side of a pool as its
being back filled takes care of the sides, but is there any thing strong enough to stand the weight of a pool 7 foot deep? I.e., is there a product that i can install in the hole that i can build the pool on? any suggestions? Steve |

Underneath i don't know if it'd handle the compression. Can anyone work out the compressive load of 2 meters of water? i.e. using supabloc 7, could it cope with the weight? http://www.tarmac.co.uk/TopBlock/DuroxSupabloc7.aspx Steve |

A cubic meter weighs near as dammit a tonne. (varies with temperature, but not enough to matter) so you are getting 2 tonnes per square metre, 20KPa or 1/5 of an atmosphere. 3 PSI even. What? The blocks are in N/mm^2! that's a barsteward unit if ever I saw one! One Pascal is one Newton per square metre, so 7.3N/mm^2 is 7.3MPa. Those blocks are easily strong enough. Whether they'll still insulate when they've soaked up ground water for a couple of years I have no idea. Andy |

Could lead to a massive failure. |

You can float a thermal cover on top when not in use. It will actually add to the water temperature on a sunny day. It prevents evaporation losses (water and more importantly heat) as well. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Yeah, what he said. From memory, mine had a layer of some sort of plastic foam, about 10-12mm thick across the floor and the sides were covered with something like extra thick hessian wadding. I think both were put there more for protection of the liner than insulation. The greatest heat loss is at the surface, a solar blanket is an absolute must. -- The Wanderer Inertia keeps me going! |

So King span is strong enough? cool. Yes it is an out side pool situated in France. I will be heating it by solar panels and my aim is to make it useable for as much of the year as possible. Ok, so i go with king span. Do i go with their thickest sheet or does it matter much? Obviously i need the pool to be stable over a good few years, so no movement in the floor is essential. Should i lay them directly on the bottom of the hole i dig, or add a concrete slab under it as well as the pool bottom slab over it? Steve |

Surely the biggest heat loss, and the one most difficult to insulate will be the top surface? My thoughts exactly. The actual m,ass of water in a pool is VAST. it is its own heatbank. The volume of soil between it and the air is also vast. Complete waste of time to insulate. |

Going from nothing to 25mm generally makes a big difference. Increasing the insulation above that makes much less difference. By far the most important area to insulate is the top of the pool, where the warmer water will tend towards, and heat loss by evaporation and wind-chill is significant. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

You'll still need to handle a lateral force of one tonne (ish) for every running metre of wall length. I should add I'm not a pool designer, but I do know a _little_ _basic_ physics. Andy |

Check out www.poolinsulation.com they have government grants to insulate old
and new swimming pools, we've just had our's done and got the insulation for free, they are really helpful our pool heats up so much quicker. url:http://myreader.co.uk/msg/1391141036.aspx |

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Nigel saying something like: Check out www.wanky-spam.com they have government grants to insulate old and new swimming pools, we've just had our's done and got the insulation for free, they are really helpful our pool heats up so much quicker.
