Our Visoglide Plus patio door looks great in both modern and traditional homes. It is precision crafted to always perform at the greatest level and offers a variety of opening options. Functionality is excellent, with inline sliding or lift and slide options available for easy, smooth operation.


Improved thermal performance
Our aluminium patio doors are designed with a polyamide thermal barrier to prevent heat loss and improve thermal efficiency, keeping you cool in the summer and warm in the winter.

High performance gaskets
When closed, our aluminium patio doors provide a magnificent glass façade that offers exceptional weather protection. High-performance gaskets are placed to prevent water penetration and draughts.
Our aluminium patio doors have been thoroughly weather tested to ensure they protect your home from drafts and inclement weather.

Highly engineered sliding mechanisms
Even the largest sashes open and close effortlessly, thanks to finely built sliding mechanics, with unparalleled ease of use. This not only ensures simplicity of use, but also increases product longevity and durability due to reduced wear.
The panels slide to one side and do not intrude into a room, making them an ideal alternative even when space is limited.
