Reclaimed Ulin Products

Why Reclaimed Ulin Ironwood

Reclaimed Ulin ironwood is valued for its exceptional durability, natural resistance to termites and humidity, and its ability to perform in demanding tropical environments. By repurposing century-old hardwood, reclaimed Ulin also supports a more sustainable approach to architectural construction and design.

We are Kaltimber, aka Kalimantan Recycled Timber, a name that conveys the philosophy of the brand as well as the emphasis on reclaiming and recycling ironwood structures.

We carefully select the best disused boats, bridges or warehouses and turn them into beautiful solid timber products including decking, flooring, ceiling, duckboard, panelling and countertops.

We then take the offcuts and transform them into unique furnitures & homewares.

With Kaltimber, your decking holds centuries of stories, and will become a heritage to be enjoyed for generations to come, a slice of history. This true re-incarnation happens under the careful hands of master craftsmen.

After all, hardwoods take thousands of years to grow and they deserve our utmost respect.

As part of our commitment we are replanting 50 ironwood trees for every 950sqm sold.

As an ethical & socially responsible business, here is our first promise to you:
 

In 2021, we initiated a trial by replanting 50 ironwood trees (Eusideroxylon zwageri). Building on this, starting January 1st, 2022, we committed to replanting 50 Ulin trees for every 950 sqm of fully processed decking and/or flooring purchased at Kaltimber. To date, we have replanted thousands of Ulin ironwood trees, and our efforts continue.

Beginning in 2025, we are expanding our reforestation initiatives by collaborating with relevant NGOs to plant other essential native species, further enhancing biodiversity and ecosystem restoration.

As an ethical and socially responsible business, Kaltimber's mission is simple: to create beautiful, long-lasting decking and flooring from recycled ulin ironwood hardwood while respecting our environment and upholding the highest standards of ethical business practices.

Meanwhile, our home décor brand i-Rewood takes production leftovers and transforms them into stunning, eco-friendly homeware.
