Our sliding doors are affordably priced to accommodate various budgets and designed to appeal to diverse tastes. They utilise the Cortizo 4700 Series, renowned for its slim design with 47mm sight lines. Available in two colours, you have the flexibility to choose the opening side—right or left—to suit your design and usage preferences. Elevate your doors further with our cutting-edge range of magnetically operated integral blinds.

Aluminium's inherent strength allows for a sleek design without compromising on durability, appearance, or practicality. Lightweight and easy to maintain, our doors feature slim, thermally broken profiles to maximise glass area with minimal panels. Advanced polyamide thermal barrier technology ensures excellent thermal performance, reducing condensation and providing insulation against noise and weather.

Manufactured and assembled in the UK, we guarantee top quality, compliance and security. Our in-house production and skilled staff ensure every door is perfect, allowing us to deliver quality products quickly and competitively.
