Real-World Reclaimed Ulin Flooring Performance

Kaltimber’s reclaimed Ulin flooring has been used in long-term hospitality interiors such as ARMA, where smooth reclaimed Ulin flooring finished with tung oil was installed in March 2020. Based on our observation, the floor has remained flat and well preserved without sanding, recoating or repair beyond normal cleaning.

This type of real project feedback helps Kaltimber advise clients on how reclaimed Ulin flooring performs indoors over time, especially in tropical villas, resorts and architectural interiors where stability, durability and natural character matter.

Why Kaltimber Developed the Exotic Finish

Kaltimber developed the Exotic Finish around late 2017 to early 2018 to preserve more of the original reclaimed Ulin surface instead of unnecessarily planing away valuable aged material. Each board is partially smoothed while retaining deeper original weathered texture, then lightly wire-brushed to create a floor with both comfort and character.

The Exotic Finish reduces waste from reclaimed timber while keeping part of the wood’s original story visible. Compared with a fully smooth floor, it offers a more textured and architectural appearance, making it especially suitable for interiors where clients want reclaimed Ulin flooring with stronger visual depth and natural character.

Kaltimber’s showroom also allows buyers to compare newly supplied wood with partially and fully exposed samples. From our observations, smooth reclaimed Ulin surfaces tend to develop a redder tone, while rustic surfaces often retain a darker appearance over time.

Reclaimed Ulin (Borneo Ironwood) Flooring

Ulin, also known as Borneo ironwood, is a dense tropical hardwood native to Borneo and valued for its natural durability, strength and resistance to termites and decay. These characteristics make it particularly suitable for long-lasting solid hardwood flooring in tropical environments.

Kaltimber manufactures flooring from reclaimed Ulin recovered from existing Indonesian structures such as buildings, bridges and other dismantled constructions. The timber is carefully selected and remilled in Bali to create solid reclaimed flooring with natural variation, character and a distinctive architectural appearance.

Reclaimed Ulin Flooring — Questions & Answers

What is reclaimed Ulin flooring?

Reclaimed Ulin flooring is solid hardwood flooring manufactured from Ulin ironwood recovered from existing Indonesian structures and processed for reuse. Ulin is naturally dense, durable and resistant to termites and decay, making it particularly suitable for long-lasting flooring in tropical environments.

Is reclaimed Ulin flooring suitable for tropical climates?

Yes. Ulin is a dense tropical hardwood with high natural durability and strong resistance to termites and biological decay. These characteristics make reclaimed Ulin particularly well suited to villas, resorts, homes and hospitality interiors in Bali and other tropical locations.

Correct subfloor preparation and professional installation remain important for long-term performance.

What finishes are available for Kaltimber flooring?

Kaltimber offers three principal reclaimed Ulin flooring finishes.

Smooth Finish

What flooring profiles are available?

Kaltimber manufactures reclaimed Ulin flooring in:

Tongue & Groove

Shiplap

Custom profiles

Custom machining can be discussed according to project specifications and quantities.

What thicknesses are available?

Kaltimber commonly produces reclaimed Ulin flooring in 18 mm and 15 mm thicknesses.

18 mm flooring is suitable for applications where boards are installed over battens or joists.

15 mm flooring can be used for applications where boards are installed directly onto a suitable prepared subfloor using an appropriate adhesive system.

The correct specification depends on the project and installation method.

What widths and lengths are available?

Reclaimed Ulin flooring can be supplied in uniform or varied widths.

Typical narrow widths are approximately 70–80 mm, while wider boards are approximately 140–150 mm.

Lengths can be supplied as random lengths from approximately 60 to 400 cm, incremental lengths, or fixed lengths according to project requirements.

Availability depends on stock and specification.

Can reclaimed Ulin be used for parquet, herringbone or chevron flooring?

Yes, depending on the design and machining requirements of the project.

Reclaimed Ulin can be used for conventional straight floorboards as well as architectural flooring layouts such as parquet, herringbone and chevron. Contact Kaltimber with drawings or dimensions so the appropriate profile and specification can be reviewed.

How much does reclaimed Ulin flooring cost?

The price of reclaimed Ulin flooring depends on board dimensions, profile, width, length selection, finish, quantity and any custom machining requirements.

Because specifications vary significantly between projects, Kaltimber provides project-specific quotations rather than using one standard price per square metre.

Contact us with your dimensions, quantity and project location for current pricing.

Does Kaltimber have a minimum order quantity?

No. Kaltimber has no minimum order quantity for reclaimed Ulin flooring.

We can supply small residential requirements as well as larger villa, resort, hospitality and architectural projects.

Does Kaltimber install flooring?

Kaltimber manufactures and supplies reclaimed Ulin flooring but does not provide installation directly.

For projects in Bali, we can recommend experienced flooring installers on request.

Recommended Flooring Thickness by Installation Method

For glue-down flooring installation, Kaltimber commonly works with 15 mm reclaimed Ulin flooring, with 12 mm also available depending on the project, substrate and installation requirements.

For flooring installed over joists, 18 mm reclaimed Ulin flooring is generally the preferred specification. While 15 mm can technically be used over joists, it requires closer joist spacing, so 18 mm remains the better standard recommendation for this installation method.

Correct ventilation and perimeter spacing are also essential. Common avoidable problems include insufficient airflow under the floor and boards installed too tightly against walls. Kaltimber’s installation guidance addresses these details to support long-term flooring performance.

Can Kaltimber supply flooring outside Bali?

Yes. Kaltimber supplies reclaimed Ulin flooring for projects throughout Indonesia and internationally.

Shipping arrangements depend on the destination, order volume and project requirements. Contact our team with the project location and required quantity so the appropriate delivery option can be reviewed.

Is Kaltimber’s Ulin newly harvested?

No. Kaltimber specializes in reclaimed Ulin recovered from existing Indonesian structures and processed for a new architectural use.

Each board is selected and processed through Kaltimber’s production system, and the company operates under Indonesia’s SVLK timber legality system.

What is the difference between Ulin flooring and Ulin decking?

Kaltimber’s reclaimed Ulin flooring is manufactured primarily for interior flooring applications, while reclaimed Ulin decking is designed for exterior environments such as pool decks, terraces, gardens and hospitality outdoor areas.

Both products use reclaimed Ulin, but their profiles, surface requirements and installation methods differ according to the application.

Where can I see reclaimed Ulin flooring in Bali?

Clients can visit Kaltimber in Bali to see reclaimed Ulin flooring samples, finishes and available specifications.

Architects, designers and contractors can also send drawings, dimensions or project specifications to our team before visiting so we can prepare the most relevant options.

Inspection, Warranty and Technical Support

Kaltimber provides inspection and case-by-case technical support when issues arise after supply. Each situation is reviewed to determine whether the issue relates to the supplied material, installation method, site conditions or service conditions.

Kaltimber’s 25-year limited warranty covers decay, fungus, termites and other borers, subject to the written warranty terms. Confirmed wood defects may be eligible for material replacement, while installation-related issues are handled with the relevant installer when a known installation partner is involved.

This approach helps clients receive practical support without turning every site issue into an unconditional repair guarantee.
