As a supplier at Heritage installations I can definately say that there is a huge difference in quality, we used to supply the Smart system but have now moved to the more advanced Schuco ASS70FD system for the following reasons: Schuco have the highest u value Door frame widths are only 70mm which are the most slimline available Each door leaf can reach 1.3m wide or 3.0m high All tracking and furniture is of commercial build guaranteeing long reliability As this product is of the highest quality, it is obviously not the cheapest, but you undoubtedly get the best product available on the market.
