About Us

2Fold® is the world’s thinnest, totally custom to you, door system. It is designed to allow the dramatic mingling of inside and outside spaces, opened or closed, both visually and physically, enhancing the beauty and functionality of any living space. This product is totally customizable. You can configure the size, number of panels and which of them swing like a door. 2Fold® was brought to life by Ed Page, Chief Engineer of Mullionz, a small window and door design, engineering and software company. Ed has been developing window and door systems since the 1970’s. Decades of experience in creating innovative products for architects and property owners while finding ways to build them out of a myriad of materials has led to the understanding of a sweet spot. Two-Fold is the perfect mix of materials, function, engineering, software and production to deliver a perfect fenestration product, quickly and reliably. We will only offer options that have been fully tested and that our engineering software can automatically generate and our production cells can produce on-time, every time to perfection.
