Indoor Heated Pool - Condensation/ Corrosion Issues
I am constructing a heated indoor lap pool. The water will be heated, but I'd like to avoid having to actively heat/ dehumidify the atmosphere in the enclosure. Dimensions are 55 feet X 8 feet X 5 feet deep. The walls will be mainly glass (North and South walls - along length) and Stone (East and West - at ends of pool).
I'd like to survey opinions and experience out there:
1. Will opening 4 doors (approx 6 feet wide) along the glass walls for a short period allow enough ventilation, after 2-3 hours use, to eliminate moisture and minimize condensation on walls and ceiling?
2. Will using a good quality pool cover, when the pool is not in use, reduce the evaporation rate sufficiently to eliminate the risk of chlorine/ corrosion damage to the aluminium framed windows and other structural elements of the building?
3. Can people suggest materials for the ceiling - obviously the main location of condensation. Will painted moisture resistant drywall board be sufficient (assuming ventilation as proposed above) or is there some other specialised material?
4. Would it be folly to assume the ceiling, if sealed conventionally, can prevent roof structural components above the ceiling to be protected from damp/chlorine. If not, would timber or galvanized steel be more appropriate?
