    Thermally Broken Roof Hatch

    All Surespan SRH/DL Roof Hatches include thermally broken extruded sections. Hence the excellent energy conservation properties and substantially reduced internal condensation and frost formation.

    In addition this reduces thermal conductivity and consequently the heat loss.

    Same technology is used in manufacture of Surespan’s Roof Hatches.
