SRHG glazed roof hatches and AOV's can be manufactured with the actuators hidden from below.

Thermally Broken Extruded Sections

All Surespan SRH Roof Hatches are available using thermally broken extruded sections, offering clients excellent energy conservation properties and substantially reducing internal condensation or frost formation.

This in turn reduces thermal conductivity and consequently the heat loss due to heat conduction through the roof hatch frame.

This can also be applied to Surespan's SRH Roof Hatches .
