Information about slimline patio doors.

It is hard to find slimline patio doors in materials other than aluminium or steel.  The inherent strength of these two metals allows for thinner profiles than PVCu, timber or hybrid patio doors.  As a result, most of the thin patio doors on the market come in aluminium or steel. However frameless patio doors also provide even less visible aluminium.

All these thin and sleek patio doors feature thermally insulated frames, a high quality construction and little compromise on security or weather performance.

Above all, what constitutes a slimline door is the visible thickness of the aluminium profile compared to standard patio doors. There are no official criteria with which doors fall into the slimline category. However, a general rule is a thin door mullion, narrow frames and thin opening door sections.
