Technical Specifications

Profile Features

Triple Gaskets

The AT 200 aluminium entrance door comes with Internorm’s industry leading weatherseals. Three, continuous gaskets sit between the framework and the door itself, ensuring total weatherproofing in all elements.

Thermal Retention Measures

The AT 200 attains excellently low U-values for an aluminium entrance door. It achieves such superb thermal efficiency standards thanks to a multi chambered profile and Internorm’s innovative foam insulation core.

Low Thresholds

Cater to all homeowners with our thermally broken, lowered threshold options. Protruding less off the ground, an AT 200 door with a lower threshold improves ease of access for anyone with mobility concerns, such as wheelchair users.

Profile Variants

Versatility is a byword for the AT 200. They can be designed in our Home Pure, Home Soft and Ambiete styles. Whatever the requirements of the commercial project, the AT 200 door can seamlessly integrate with the aesthetic.


Secure, easy to operate and eye-catching handles will be installed to each AT 200 entrance door you supply for your commercial project. Their sleek design is in-keeping with the visual appeal of the aluminium profile.
