Three-side support swimming pool windows are supported along three edges, the two vertical jambs and bottom sill. Most commonly, three-side support panels are installed into a U channel rebate that incorporates a cantilever design. This type of panel is commonly utilized in the construction of infinity edges, spa partition walls and freeboards. Transparencies of this design have a polished top edge in order to provide an aesthetically appealing appearance that is safe for handling and usage.
