In an extension of the Standard Model with one extra dimension and N=1 supersymmetry compactified on R^1/(Z_2 x Z'_2), we compute the Higgs boson decay width into two gluons, relevant to Higgs production in hadronic collisions. At one loop, the decay width is significantly suppressed with respect to the SM. For a compactification radius 1/R = 370 \pm 70 GeV and a Higgs mass m_H = 127 \pm 8 GeV, as expected in the case of a radiatively generated Fayet-Iliopoulos term, we find it to be less than 15% of the SM result.
