Thermally Broken Roof Hatch
Surespan glazed roof access hatches use thermal brakes. As a result, they offer clients excellent energy saving properties. They also greatly reduce internal condensation and frost formation.This in turn helps with thermal conductivity. Consequently, this reduce the heat loss due to heat conduction through the roof hatch frame.
Glazed roof hatches and smoke vents have hidden actuators. As a result, the hatch gains a sleek look and you can’t see the mechanism from below.
Surespan manufactures glazed roof hatches using thermal brakes as standard. Thanks to this, our products offer clients great energy saving properties and reduce internal condensation or frost formation. Surespan glazed roof access hatches have a frameless design against water ponding.
The upstand height vary to suit the fitting of the hidden actuator.
The aluminum frame and upstand have a thermal break as standard. The upstand’s outer section has a layer packed with 50mm of insulation. This prepares the upstand for weathering on site at time of installation by others.
The hatch comes with twin 24v DC actuators at the remote end of the access opening. We produce our glazed hatches with the actuators hidden behind an aluminum sheet. As a result, when viewing from below with the cover closed they are out of view.
The synchronised actuators ensure an even lift when used with a Surespan control panel. Also, the hatch offers an option of wiring directly into the Fire Alarm or Building Management System by others.
We recommend applying a polyester powder coated finish to the lid frame and upstand. Alternatively, standard finish is aluminium mill finish.
