SRH/DL double leaf roof access hatches are manufactured in aluminium. They can be provided with an optional polyester powder coated finish. Each standard roof hatch is insulated to maintain the thermal integrity of the building.

The gas spring assisted opening lid is supported by heavy-duty aluminium hinges. This also features an integral ‘wrap over’ edge. The hatch incorporates double unbroken EPDM seals. The upstand has a purpose made flashing to accept the roof felt for weatherproofing purposes. Moreover, the hatch incorporates a safety hold open stay feature to prevent accidental closure. Various locking options are available.

Hydraulic Operation

Hydraulic operation

The hydraulic system includes operating cylinders and a hand pump. A typical access cover panel would take around 60 seconds to open from a closed position.

The hatch closes on a release of the hydraulic oil from the cylinder. The weight of the cover is sufficient to push the cylinder closed.

Pneumatic Operation

Pneumatic operation

The pneumatics provide a clean and efficient way of operating our hatches. This method is designed for the environments where compressed air is freely available or is preferred to hydraulic cylinders or electrical actuators.

The system includes operating cylinders fed from a manual control manifold. This manifold can connect to a ring main pneumatic supply.
