Why choose a Cortizo Inline Patio Door
Cortizo Inline doors allow for the maximum surface area of glass creating panoramic views and floods of natural light into your living space creating an airy, relaxing environment. These doors look fantastic on homes of all shapes and sizes, the slim profiles work in ultra-sleek modern homes while ensuring they don’t stick out on the more traditional home.
Cortizo patio doors feature a thermal break design that minimises heat transfer between the interior and exterior of the building. This results in improved energy efficiency, reduces heat loss in the Winter and helps to maintain a cooler home during the Summer.
