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.
Here’s what we promise:
Our woods last a long, long time and so will your hardwood decking and flooring!
Our reclaimed ulin ironwood hardwood is renowned for its durability and natural resistance to termites and decay. Whether used for decking or flooring, this ancient wood is built to stand the test of time, ensuring your spaces remain strong and stunning for years to come.
We will always tell you where our wood comes from.
We take pride in our transparency. You will always know the full journey of your ulin ironwood, from its origin to your home. Our chain of custody ensures that every piece of wood in your decking or flooring comes from responsible, ethical sources, giving you peace of mind with every purchase. And if ulin isn’t the perfect fit, our partner Kitaru Lumber Yard offers other sustainable options.
Responsibly Reclaimed and Recycled
We believe in giving old wood a new purpose. Every piece of our ulin ironwood comes from responsibly salvaged sources, such as old structures and post-consumer materials. Through careful selection and re-milling, we ensure that these timbers retain their strength, character, and durability. By using recycled ulin ironwood hardwood, we reduce the need for fresh logging, minimize waste, and help protect our forests for future generations.
Reducing waste while producing hardwood decking and flooring is one of our top priority.
Our commitment to sustainability extends beyond just decking and flooring. Through our other brand Naturanexa, we create sustainable building components from reclaimed ulin ironwood hardwood. Meanwhile, our home décor brand i-Rewood takes production leftovers and transforms them into stunning, eco-friendly homeware.
By maximizing our use of materials, we ensure nothing goes to waste while offering you even more sustainable options for your home.
We respect natural resources and use our wood wisely.
We respect natural resources and use our wood wisely. We won’t muck around when it comes to forests. Guided by our Environmental Policy, we intentionally design around our materials to reduce waste and maximise the inherent beauty of our timbers. After all, they are older than we are and deserve our respect.
Respecting Nature, Always
Ulin ironwood hardwood is more than just a material—it’s a piece of history. We honor that history by designing around the natural beauty of the wood, preserving its inherent character and uniqueness.
