What to consider when installing or renovating an indoor pool ceiling

Existing grid that has become discoloured can be repainted, but it is labour-intensive and time consuming. An alternative is to apply grid covers, thin plastic extrusions that snap onto the tees to conceal the old, unsightly faces. They can usually be installed without removing the ceiling panels and are available in colours to match or contrast with the panels.

One of the most common types of ceiling panels are made from mineral fibre. Despite their popularity, they are not the best fit for indoor pool applications. Typical mineral fibre panels offer moderate-to-good control of noise, but are vulnerable to moisture-related damage, prone to staining, and are easily dented or broken by impacts such as a high-flying water-polo ball. Special grades of mineral fibre, suitable for humid conditions often found in indoor pool environments, are available for a premium price.

Metal panels are also available, although steel products are not recommended for pools because of corrosion potential. Some perforated aluminum panels with an anodized or painted finish are suitable for above-pool use. However, metal panels can have razor-sharp edges that could be hazardous if a panel got knocked out of the grid—by a ball used in pool sports, for example. To prevent accidents, all types of over-pool ceiling panels should be secured in place with hold-down clips.

Another appropriate option is a thermoformed ceiling: thin, lightweight, three-dimensional panels available in a wide variety of both contemporary and traditional styles and in a range of colours. Thermoformed panels are impervious to water, stain-resistant, washable, and durable. At least one brand of thermoformed panels has been specifically tested for staining by pool chemicals and found to be highly resistant. In standardized strength testing, the panels did not chip or abrade, and tend to flex upon impact instead of breaking.
