A continuous process is used to make concrete building products with an expanded polystyrene core. The expanded polystyrene is fed into the inlet of an elongated guiding channel which has a longitudinally split mold. The expanded polystyrene is guided along the guiding channel without any means for pulling the expanded polystyrene. Concrete is then pumped into the split mold first through an first aperture in a first mold section of the split mold and then through another aperture, in a second mold section of the split mold, so that the concrete is coated on at least two opposing sides of the expanded polystyrene.

1. A continuous process, with upstream-and downstream longitudinal directions, for making an elongated coated building product comprising a longitudinal expanded synthetic polymeric form having a desired cross-sectional shape, and having a longitudinally continuous coating of a facing material on at least a portion of a periphery of the cross-sectional shape, said process comprising:a) feeding the expanded-synthetic polymeric form longitudinally into the inlet of an elongated guiding channel which comprises a longitudinally split mould having an internal cross-sectional shape suitable to produce a desired external cross-sectional shape of the coated building product; b) guiding the expanded synthetic polymeric form along the guiding channel, without any means for pulling the expanded synthetic polymeric form after the expanded synthetic polymeric form enters the inlet of the guiding channel; c) feeding the facing material into the split mould through a first aperture in a first mould section of the split mould.
