Overhead Sectional Doors ISO


ISO 40

The all-rounder

The ISO 40 mm sectional door is Alpha’s most popular door, a modern design that unifies excellent thermal insulation and sound-absorbing qualities in its micro-profiled panels. The choice of design and materials are endless, which means the door can always be perfectly configured to meet your wishes. Numerous types of built-in windows as well as different heights and widths make up the ISO 40 mm range, as well as a wide variety of Alpha’s in-house RAL colours.


ISO 60

The effective partition between climate zones

ISO 60 mm sectional doors are overhead doors with extra-insulating and sealing properties that are mainly used in locations where the division between different climate zones is important. If you need to keep your production hall or storage area at a constant temperature, the ISO 60 mm door is the right one for you. The micro- profiled steel plate panels have excellent sound- absorbing and heat-insulating properties and they can withstand all the elements.


ISO 80

By offering optimum insulation performance coupled with a U value of 0.25 W/m2K, the ISO 80 satisfies the requirements of customers who want to construct buildings (or have them constructed) in accordance with today’s standards. As a result, this door is ideal for cold stores and refrigerated warehouses, industrial buildings, warehouses and distribution centres where heat loss is a major risk and/or where the temperature of the goods must be guaranteed.
