Thermally Broken Roof hatch

Our roof hatches are sold with a thermal break to eliminate issues that arise from thermal bridges (where two conductive materials meet allowing passage of heat).

Normal roof hatches conduct energy easily due to the thermal bridging. The biggest issues, arises from humid environments where temperature differences leads to condensation forming.

Surespan has incorporated a thermal break in its roof hatches as standard. The role of this thermal break is twofold – it maintains its structural integrity by holding two metal profiles together and that it is a poor heat conductor, therefore disrupting the flow of energy moving from inside to outside, and vice versa.

Thermally Broken Sections

SRH/ZIP/JAK Full Access Package

SRH Roof Hatches can be manufactured with an extended skirt liner. The extended skirt liner can be used on any type of roof and can be provided as a completely assembled unit. This unit comprises of an SRH roof hatch, extended skirt liner, wall mounted rung, vertical fixed ladder and a ZIP retractable ladder.

For metal deck roof applications, the extended skirt liner gives an attractive look to unsightly metal edging. In general circumstances, it gives a lining to the inside of the aperture.

The JAKDOR ceiling access door is to be fitted once the unit has been fully installed.

The extended skirt liner can be manufactured to your exact requirements: no shape or size has its restrictions.

Handle and Cord Lid Closing

SRH Roof Hatches can be manufactured to enable the lid to open separately to the safety grid. In this instance, when exiting the roof hatch and closing the safety grid, there needs to be a means of manually closing the lid.

The handle and cord is connected to the lid of the hatch and easily fits between the safety grid to enable the lid to be closed with ease.
