SRH/ES Roof Hatch with Extended Skirt

SRH Roof Hatches can be manufactured with an extended skirt liner. The extended skirt liner can be used on any type of roof and can be provided as a completely assembled unit. This unit comprises of an SRH roof hatch, extended skirt liner, wall mounted rungs, vertical fixed grab rail and a ZIP retractable ladder.

For metal deck roof applications the extended skirt liner gives an attractive look to unsightly metal edging. In general circumstances it gives a lining to the inside of the aperture.

The JAKDOR ceiling access door is to be fitted once the unit has been fully installed.

Metal deck roof applications

 

Skirt Angle

The extended skirt liner can be manufactured to your exact requirements. No shape or size has its restrictions.


Thermally Broken Extruded Sections

All Surespan SRH Roof Hatches are offered with a cost option 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 SRHG Roof Hatches.


Solar Powered Roof Hatches

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.

Handle and Cord Lid Closing

SRH Roof Hatches can be manufactured to enable the lid to open seperately to the safety grid. In this instance when exiting the roof hatch and closing the safety grid, there needs to be a means of manually closing the lid.

The handle and cord is connected to the lid of the hatch and easily fits between the safety grid to enable the lid to be closed with ease.
