SAPA Crown Patio Doors Trade Supply
We offer high-quality fabricated trade supply SAPA Crown Patio Doors. We expertly manufacture SAPA Crown patio doors in a choice of either 120mm systems or 98mm system.
Both are designed for residential or light commercial use. Doors feature several benefits to the end user and the installer. The 120mm system is suitable for those that require a sliding patio door with a deeper frame. The 98mm system offers a slimmer frame dimension front to back.
This makes the 98mm version suitable if you are replacing old doors with new. The slimmer frame dimension means less cutting back of internal plaster. Regardless of option, both variants of the SAPA Crown patio door offer great features and benefits.

Aesthetics are designed for residential use having slim sight lines. You can choose from inline aluminium sliding doors in a 2, 3 and four pane configuration. Leaves can slide either to the left or the right. Aluminium profiles have the latest in polyamide thermal break technology. Not only does this make for a highly thermally efficient door but also offers dual colours if required.
Profiles are designed for inherent strength featuring strong interlocks, anti-lift devices and optimum security (6-point multi-point lock). For your customers requiring a taller than average door, heights up to 2500mm are possible with each sliding leaf up to 1600mm in width. Also, because these doors are designed to complement the SAPA Crown Range of Windows, similar handles to the SAPA Crown and SAPA Dualframe range are available.
