No, the laminate stock was introduced in the mid to late 1950s, long after the types shown in the photo and there was no such thing as non-gangway laminate stock. The laminates were a development of the Park Royals, having a smoother external appearance. Like the Park Royals, the laminates were 10' 2" wide, but unlike their predecessors this width was carried through the full length of the vehicle.
The vehicles in the photo are ex-GSR and GS&WR stock: The one nearest the camera, 4042, dated from 1928 and was built as a 1st / 3rd Compo (50F and 48T class seats). It was 60' 0" long, had a side corridor and was gangwayed. The next coach looks like it could be 4001 - the number isn't quite clear. If it is 4001 then it was built as a 96-seat, non-corridor third class coach and dated from 1907 It was 45' 0" long. It didn't have gangways. At the time the photo was taken, both vehicles were classified as 'Secondary' stock by CIÉ, hence the 4xxx numbers. Secondary stock was a fleet of vehicles retained for use on special occasions or times of high demand - for example summer Sunday suburban services, or extra services for GAA matches.
