Aluminium Sliding Doors

Proudly Serving Leicestershire & the East Midlands For Nearly 40 Years

Why Choose Sliding Doors?

The Slimline Sliding or Lift & Slide system, which is also known as the ESS47 hybrid sliding patio door system, is designed for big spaces of up to 2.5m x 2.7m per section. Our super slim interlock is just 25mm to allow for maximum vision, and excellent thermal performance of just 1.4 U W/m2K, noise reduction, high security and weather-proofing.

The Aluminium Sliding Doors Soft Closing technology allows for smooth operation. For doors that do not occupy the inner space or to integrate rooms such as an Extension Living Space or Kitchen Dining Area.

Our sliding patio door system gives almost unobstructed views with the use of narrow profiling which are designed with bottom rails of 42mm and 34mm width to allow for that perfect view.
