Indoor aquatic center environments are a bit tricky to deal with. After extensive team collaboration with the owner, it was decided that the best short and long term solution was to remove the existing material and replace with a metal deck and roof assembly provided by the IMETCO team. Three critical items were identified and remedied with the solution provided:

• Protect the acoustical metal deck and screws attaching the metal deck from corrosion.
  A high performance polymer coated corrosion resistant acoustical metal deck, fastened with 316 stainless steel screw deck deck fasteners, was ultimately chosen. The polymer powder coating was applied after the perforations were punched in the steel deck so the holes were completely coated. For additional protection, the fiberglass acoustical batts located in the deck flutes were wrapped in thin visqueen plastic.
• Provide moisture protection for the roof assembly from both inside and outside the building.
  Our high performance air and vapor barrier was completely and smoothly adhered over the water resistant roof board to stop moisture mitigation into the insulation. The air and vapor barrier was also properly tied into roof transitions and edges of the building. Our high temperature AquaBlock roofing underlayment was applied to the top side of the insulation to waterproof and protect the inside of the building.
• Provide high performance protection from future condensation.
  There will be no condensation worries, as our air and vapor barrier was positioned directly below the high density R-30 continuous polyiso insulation. The continuous zee girt was also embedded within the insulation, assuring no condensation as a result of penetration through the air and vapor membrane from the outside of the building.
