Bi Fold MB70

What you need to know

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum

About the product

Aluminium folding slid system MB-70 - 

Whether winter gardens, terraces or balconies - the aluminium folding door system MB-70 is the ideal solution for the highest possible incidence of light on large areas. The aluminium profile is light, but still extremely stable and therefore ideally suited for wide glazing. The running rails are attached either to the upper frame (top-hung) or to the threshold (bottom-hung). The folding sliding door simply slides along them - after the door leaf has been operated - 
The 3-chamber profile achieves excellent thermal insulation values. In addition, window and cover seals made of EPDM and a centre seal, consisting of a two-component EPDM, protect against driving rain and wind. Optionally, you can also opt for triple glazing or ornamental glass. An extensive range of 200 RAL colours is available for exciting accents for personal design.
