Surespan SRHG Glazed Roof Hatches are manufactured using thermally broken extruded sections as standard, offering clients excellent energy conservation properties and substantially reducing internal condensation or frost formation.
Surespan glazed roof access hatches incorporate a frameless design eliminating water ponding. The low profile frame with triple seals is structurally bonded to the 35.5 mm thick double glazed unit comprises SGG Planitherm Ultra N2 6 mm toughened glass, 20 mm argon filled cavity with thermal warm edge spacer bar, and a 9.5 mm toughened and laminated inner pane.
Note: We recommend all glazed hatches to be installed on a 5° pitch to stop water ponding.
SRHG roof hatches are custom made to any size. Please specify the width and length of your hatch below.

All Surespan SRHG Glazed Roof Access 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 Access Hatches.
SRHG Glazed Hatches can be manufactured with clear, opaque and smoke glass options. In addition the glass can be self-cleaning or walk on. Contact Surespan Sales for further information on glass specifications.
Opal (opaque) glass.
SRHG glazed roof hatches and AOVs can be manufactured with the actuators hidden from below.
All Surespan electrically operated roof hatches are available using solar technology, offering clients an environmentally friendly alternative.
A 12V solar panel is fitted either onto or nearby the roof hatch, harnessing solar energy to charge it's batteries and allowing the hatch to automatically open and close using a completely wireless system. This can be operated by either a wireless switch or remote control. It's batteries are fitted with a conditioned monitoring feature which sounds an alarm if they are running low or indicate a fault.
Additional options including being linked up to the building's Fire Alarm System (FAS) or Building Management System (BMS) are available. Multiple roof hatches can be operated by one solar panel.
This technology can also be applied to Surespan's SRHG glazed roof hatches.
Surespan hatches can be fitted with curb liners to ease site installation.
Surespan hatches can be fitted with expanded mesh around the curb liner to aid adhesion for asphalt.
All Surespan hatches can be provided with an encased upstand and run-off skirt.
Safety grill/ladder extension provided for safety and convenience, acting as a barrier or ladder extension when upright and a security grill when folded down.

Twin colour access hatches are becoming a very popular option.
Surespan access hatches are supplied with a 200mm upstand as standard. However, we can produce any height or raked upstand to suit your requirement.
Surespan hatches are designed to offer a high level of thermal insulation against heat loss and condensation. U-Value of 0.43W/m²K is available.
All Surespan access covers are available polyester powder coated to any standard RAL colour.
Surespan access covers can be rated for 3 hours fire resistance for integrity to BS476: part 22: 1987.
