Technology & Design

Slender aluminium profiles in your Schuco ASS70 bifolding door come with built-in thermal insulation offering outstanding strength and excellent energy efficiency.  The interior and exterior powder-coated surfaces offer colour choice with durability and low maintenance. All you need is a routine clean of your door frames to keep your new doors looking good for years to come.

Schuco doors come with all the weight at the bottom of the doors.  As a result, our doors offer a superior slide and fold action with no risk of bowing or deflection at the head of the frame.  This preferred bottom-rolling method also makes designing your new extension easier with no structural calculations needed at the head. 

Even better is the choice of four different threshold options to meet different access and weather performance requirements as well as creating stylish room dividers. 

The Schuco ASS70 bifolding door is perfect for replacing your old patio doors as well as a new extension project.  Choose from doors from 2 up to 10 panels, opening in or out, sliding in many different ways and even including an open corner option.  We can even integrate an opening window into a door panel.

Product Features


The German engineering and design behind every Schuco bifolding door are thanks to the dedicated hardware, door components and technology. All of these factors result in a door that's arguably the smoothest on the market, effortless and reliable to use every day. The hardware also complements the door perfectly with attention to detail and overall quality.

It is also the quality hardware with slim strong aluminium profiles, making Schuco one of the few doors on the market capable of 3 metre door heights.

The catch on the Schuco ASS70 bifolding door works differently from conventional door magnets holding the door better in stronger winds and having tension adjustment too.


Quality glass units make your Schuco ASS70 bifolding doors safe and secure while helping with energy efficiency.

Glass units come with warm-edge spacer bars, a soft coat low-emissivity coating and argon gas-filled to both toughened or upgradable laminated glass. As with all our bifolds, Schuco also comes with options for self-cleaning, solar control, acoustic glazing and triple glass.


Schuco products come in all manner of contemporary powder coated and anodised metallic finishes, giving you a contemporary looking bifolding door with durable, low-maintenance colours.

Powder-coated colours come in over 150 different colours as well as the latest generation of metallic shades, textured surfaces or a different colour inside and out.

For an even more striking door, look at anodised finishes, offering silver, black, grey, bronze or gold colours in a classic metal appearance and with the best surface coverage and durability.

Every one of our Schuco bifolding doors comes with a professionally applied colour with a 10, 15 or 20-year guarantee depending on the colour and application.

Energy Efficiency

Schuco is renowned for providing thermally efficient windows and doors to low energy buildings all over the world. The bifolding door product features deep thermal breaks, insulating the aluminium and creating a thermal bridge. Heat is retained in the home, cold stays outside. The thermally broken aluminium profiles work with our high specification glazing and give Schuco doors some of the best U-Values in the industry.

For you, this means a warmer in winter, cooler in the summer home. The doors help lower your energy bills and exceed the requirements of current Building Regulations. Our doors glazed with a standard specification unit achieve U-Values of 1.7Wm2K and even better with enhanced glass. There is also our ASS80 model with thermal inserts for even better performance.
