Surespan SRH/DL double leaf roof access hatches are manufactured in aluminium with an optional polyester powder coated finish. Each SRH is insulated against heat loss and condensation to maintain the thermal integrity of the building. Weighted sound reductions can also be incorporated.
The gas spring assisted opening lid is supported by heavy-duty aluminium hinges and features an integral 'wrap over' edge, incorporating double unbroken EPDM seals. The upstand has a purpose made flashing to accept the roof felt to make it weatherproof. The hatch also incorporates a safety hold open stay to prevent against accidental closure. Various locking options are available.
