D-50T roof hatches are designed to be used for the movement of equipment on and off the flat roof area. All units are built to the specific site requirements, from small to very large.
They are ideally suited for use in office buildings, flats, factories, warehouses, retail stores, shopping complexes, hotels, manufacturing plants, hospitals, schools, auditoria and sports facilities where roof access is a requirement.
They are manufactured to provide a high degree of thermal efficiency and are supplied with 50mm of polyisocyanurate insulation to both the upstand and the cover.
In addition, the cover is fitted with a closed-cell EPDM gasket designed to reduce the air leakage though the closed cover, ensuring that the air leakage requirements of Building Regulations Part L are achieved.
A counterbalancing spring mechanism ensures that all hatches are easily operable by one person to assist designers and employees in meeting the requirements of the Manual Handling Regulations.
The acoustic, thermal and air leakage performance of these hatches, as well as their resistance to wind and snow load and to impact, has been independently verified by tests at Taylor Woodrows technology centre in Bedfordshire.
