This picture illustrates why our modular building system is hybrid. It shows a polyurethane foam block attached directly to a polyurethane foam wall panel. Try finding another modular building system that can do this!
All of our panels are “female” when they are manufactured. A female panel side can quickly be converted to a male panel side by installing lug inserts. A lug insert is shown resting on the table in front of the panel.
In this picture female side of the block is engaged with the male side of the panel. The male side of the block could just as easily have been engaged with a female side of the panel.
