GS-50TB ladder access roof hatches are designed for personnel access where a fixed vertical ladder is being used and has the added advantage of a double-skin polycarbonate dome to allow natural daylight into the area below.

They feature a thermally broken frame and cover design that minimizes heat transfer between interior and exterior metal surfaces, giving a high degree of thermal efficiency. They are supplied with 75mm of polyisocyanurate insulation to both the upstand and the cover.

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.
