E-50TB roof access hatches are designed for personnel access where a fixed vertical ladder is being used and for moving small pieces of equipment to and from the roof area.

They are manufactured with a thermally broken frame to provide a high degree of thermal efficiency and are supplied with 75mm of polyisocyanurate insulation to both the upstand and the cover.

The design minimises heat transfer between interior and exterior metal surfaces. The result is a product that resists harmful condensation and provides superior energy efficiency

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.
