What are Bifold Door Sightlines?
When you look at a set of bifolding doors, the distance between a pain of glass on one door and the pain of glass on another door is called the sightline - basically it's the full width of the two frames of a door where they meet.
An important benefit of modern doors is that they have slim sightlines to allow more light into the home and less frame gets in the way of your view of the garden. This creates a more stylish look and feel.
However, style and slim sightlines are nothing without the strength and security that materials like aluminium brings. The frames of our most popular bifold door, the Origin Aluminium are extremely strong and yet weigh 67% less than steel.
