Whether you want to build a new home or retrofit your existing home, Paarhammer external doors with an optional level threshold that stops drafts, noise and water are the ideal solution and provide safe access for all. Now the zero-threshold designed and patented in Germany has received several awards.


ALUMAT is the recipient of the German Design Award for the zero-threshold, and also recently received Passive House certification. In addition, this magnetic threshold has been recognised by the internet platform ‘bfb – barrier free building’. bfb determines annually the best barrier-free building products and solutions that enable comfortable and safe life at any age. The ALUMAT magnetic threshold was selected as the ‘Product of the Year – 2021’ by an expert jury evaluation and a reader vote.

How it works

When the door is closed, two double seals with silicone contact in the threshold are automatically attracted to the two magnetic strips at the bottom of the door. The seals come up from the level threshold, meet the magnets, and seal the bottom of the door. When the door is opened, the magnetic field is broken and the seals drop back into the threshold, making it a level surface.

Enjoy peace of mind with a 20-year warranty on the magnet force of the threshold, and barrier-free accessibility means easy traffic movement between spaces with no risk of stumbling.


ALUMAT barrier-free thresholds are most often used for entrance doors and French doors. Paarhammer doors are manufactured locally in Australia and custom made to your specifications. The full package includes door jamb, threshold, multi-point locking system and door furniture, ensuring energy efficiency and sound protection. Automation can also be integrated.

With Paarhammer and ALUMAT, incorporate style, great design and modern technology, all while achieving energy efficiency and thermal insulation.
