Description

SIGA MAJREX® 200 is a unique and revolutionary Vapour Control Layer unlike any other on the market. With its patented Hygrobird® technology, it allows for the travel of moisture from within the wall through into the room but not back out into the wall.

SIGA took inspiration from nature and the Cactus, which absorbs moisture through its skin at night when the moisture in the air condenses. But during the day when temperatures rise above 40℃, the cactus manages to keep all the moisture inside so it doesn't wither or die. The skin of some cacti lets moisture in - but not out.

The development of an actual one-directional membrane is a big step forward in building physics. We can now have the best of both worlds in one product:
- The high amounts of moisture from the inside does not pass into the wall cavity.
- At the same time, the moisture we have in it can easily pass through the membrane towards the inside where it is not harmful.

There’s no other product in the world like it… except for the cactus of course.
