Industrial > T80 ISO-A80 ISO

Looking for an overhead door with the best insulation value? Then select a door with 80-mm thick sections.

“The highest class of insulation.”

The 80-mm panels are available in steel (T80) and in aluminium (A80). The 80-mm doors are completely thermally separated.

The T80 ISO has plastic end profiles to eliminate the formation of condensation. The double seals around the door guarantee high insulation. Do you want even more insulation? Then you can install the Insulator.


The T80 ISO is an 80-mm thick steel sandwich panel that is fully thermally separated and as such offers an energy efficient solution. The fire-retardant polyurethane foam core skinned with steel results in an extra high insulation value.

The steel panels have a Stucco finish with horizontal lines on both the inside and outside. The inner skin is finished as standard in RAL 9002. The outer skin is finished in a RAL colour of choice.

Available colours

The T80 ISO panel is available in three standard RAL colours: 9002, 9006 and 7016.


The A80 ISO overhead door is constructed from horizontal aluminium sections that are thermally separated. The sections can be made to specification and can be fitted with many types of filling and/or glazing. As standard, the aluminium sections have quadruple glazing. With an A80 ISO door, optimum insulation is guaranteed and in addition, a lot of daylight enters the building.

For additional light transmission and a stylish appearance, the A80 ISO sections are frequently used as glazed section in an T80 ISO.

The sections are as standard made of anodised aluminium. However, they can also be powder coated in any desired RAL colour (according to the Qualicoat standard).
