Concave Three-Side Pool Window

Concave Three-Side Support Pool Windows

Three-side support concave windows protrude inward in a curved fashion. These panels make for an elegant custom pool design.

When creating concave windows for swimming pools, exacting standards must be met. The process involves using a custom female or male end mold, depending on your install configuration. An acrylic sheet is placed on top of the mold and heated until it takes on the shape of the mold. When cooled, the window is finished and the desired edge style applied.

At Acrylic Pools, we take extreme care in producing concave windows to eliminate the potential for failures due to surface stress and improper dimensions. Some fabricators cut corners when producing such windows to save time and money. Acrylic Pools always takes every step necessary to ensure its pool windows are of the highest quality, so you can have the effect desired for your pool with complete structural integrity.

Edge Designs

Several edge options are available in three-side acrylic pool window configurations. These edges are selected based on the intended application of the window and the appearance you want to achieve.

Radius Edge

A radius edge is the preferred finish for the top of an acrylic support panel. This edge style is often used in both freeboard and infinity configurations. It provides safety as well as an appealing look that enhances your pool’s design. A radius edge typically ranges from 3/8” to ½”, though alternative dimensions are also available.


Bullnose Edge

A bullnose edge is an upgraded feature that provides a rounded top to the window. This allows for an edge-free finish. Bullnose edges are commonly used in partition spa pool walls, providing a smooth transition between wet and dry panel faces.

Custom Edge

If you have a specific edge style in mind, Acrylic Pools can create and fabricate it for you. We work at your request and provide pool window edges that will exceed your expectations.
