Modern and versatile inline sliding door from outside

Create a minimal and contemporary look for your home with the versatile and premium BSC94 Inline Aluminium Sliding Door


Combining high performance with stunning contemporary design, our sliding aluminium door systems provide a versatile solution for any new or refurbished home.

Manufactured to the highest UK standards, this multi-configuration inline system offers outstanding thermal performance and a wide range of customisable options. In-line sliding doors are the most popular form of slider, where the door sits on rollers which glide across when opening and closing the door.

The BSF94 Inline door has a maximum panel weight of 400kg, allowing bigger sashes up to 3000mm high and 2000mm wide for truly panoramic views.

The BSC94 Inline Sliding door offers slim sightlines of as little as 45mm, allowing more light transmission and more impressive views.

The sliding door is available in mono, dual and triple rail options to suit your design and fit the available opening space.

Available in single or dual colour polyester powder coating, texture and anodised finishes, you have all the design freedom you require to create a truly unique space.
