The selection included the Surespan SRHP/50/TB37 Roof Hatch in three sizes: 1000 x 1000mm, 900 x 900mm, and 950 x 950mm. Key features of these hatches include a 300mm upstand and LO1, LO2, and LO4 locking mechanisms, providing secure access to the airport’s rooftop areas.
The hatches are insulated with either Kooltherm or Kingspan material, known for its superior thermal properties. Additionally, each hatch is equipped with an external kerb liner, a thermally broken lid and upstand for enhanced durability, and a gas spring assisted opening to 85°, alongside a double unbroken EPDM seal for optimal weather resistance.
Further emphasising Surespan’s dedication to safety and compliance, we also supplied the Surespan SRH/TB/FR120 Fire Rated Roof Hatch, measuring 600 x 600mm, which incorporates mineral wool insulation to achieve optimal thermal efficiency. This hatch boasts a fire resistance rating of up to 240 minutes according to EN 1634-4 standards and holds UL-EU certification for up to 4 hours of fire resistance. Mirroring the design ethos of its counterparts, it features a thermally broken lid and upstand, an external kerb liner, and a double unbroken EPDM seal to ensure long-lasting performance and safety.
