Internal sliding doors

[trouble99]

In the middle of an extension, an extra room onto the kitchen. In the architect’s plan he has recommend to fit one HW sliding door, single glazed laminated glass (One fixed leaf, one sliding) opening width 2 metres and at the other end of the room to fit a sliding door 950mm wide, from the 2 access points of the existing room into the new room. The glazing is to be safety glass. The idea is to close off the open plan area if we wanted and for heat reasons in the winter. Would anyone have any recommendations of products to install with some pictures?

Thanks in advance for any information
