Timber sliding patio doors are a great choice if you want to make the most of your views into the garden or beyond. Large panes of glass give uninterrupted views and lots of natural light. Our timber sliding patio doors run on a high-performance rail system designed to ensure an easy glide. Weight is not a problem because the system is highly durable and also makes opening the doors effortless.
Sliding doors are beneficial when you don’t have space inside or outside for doors to open. The opening door slides behind the fixed panel, making them ideal in kitchens, entrances and even bedrooms with Juliet balconies.
We offer several sliding patio door configurations to suit the layout of the room and the size of the reveal. All configurations allow for large and heavy doors (up to 400kg in weight) to be specified without compromising the sliding performance. There are also secure night vents which leave a 10mm opening. This is ideal when used in a bedroom, for example, when you want nighttime ventilation.
