Wood cladding, siding and panelling, inside and out.

Hardwood Cladding & Siding

Exterior cladding and siding, interior wall panelling and slatted ceilings in tropical hardwood, recovered from forests that have stood beneath reservoirs for over 30 years, for projects in the UK and the US. Enough of each species to clad a whole facade, with nothing newly felled and every batch traceable.

Why submerged hardwood for cladding and siding

Made for exposure

Triton recommends its Studio species for construction, cladding, decking and joinery, and they keep the technical performance of tropical hardwood after decades beneath the water. Balata, known elsewhere as Massaranduba, is very hard and naturally rot-resistant, and Acacia Franc is very durable and suited to work exposed to moisture. Shown: concept rendering.

Hardness, stability and acoustics

Triton reports greater hardness and stability in its submerged timber, along with the sought-after acoustic qualities of noble hardwoods. In the words of Elodie Delonca of Triton, these timbers are "naturally durable, mechanically resistant". Shown: concept rendering, Inkassa slatted ceiling.

Enough for a whole facade

Reclaimed cladding has always been limited by what a single barn or building could give. Around 9 million cubic metres of timber lie in the reservoir, with 3.5 million planned for recovery over 25 years, so a facade, its soffits and its decking can share one timber and tone. Volume, grade and lead times are confirmed at specification. Shown: concept rendering.

Inside: panelling, shelving and joinery

Indoors, the same timbers line walls, form shelving and continue into doors and staircases. Acacia Franc is traditionally used for panelling, floors and stairs, and Angélique for interior and exterior joinery. Shown: concept rendering, Inkassa floor, panelling and shelving.

The cladding species

Triton recommends its Studio species for construction, cladding, decking and joinery: Balata (Massaranduba), Acacia Franc, Angélique (Basralocus), Cumaru, Courbaril (Jatoba), Chawari, Gonfolo, Wapa, Grignon Franc and Bois Rouge. For interiors that call for something seldom seen, the Rare species are prepared to order over a longer lead time. Shown: concept rendering.

Traceable, with nothing newly felled

Every board comes from trees that were already lost beneath the water, so no living forest is cut. The timber is harvested under a 25-year contract with the national forest office, and each batch ships with a Certificate of Guarantee of Origin, so species and origin are documented for every shipment, in the UK or the US.

Sunken, submerged or bog oak?

Three kinds of timber come back from the water, and they are not the same material. Our guide explains how each one forms, how it looks and where it is used.

Wood Cladding & Siding FAQs

Which wood is best for exterior cladding or siding?

Dense, naturally durable hardwoods. Triton recommends its Studio species for construction, cladding, decking and joinery; Balata (Massaranduba) is very hard and naturally rot-resistant, and Acacia Franc is very durable and suited to work exposed to moisture. Technical data for each species is available on request.

Which species suit interior wall panelling and ceilings?

The Popular species run from pale to deep brown and can line walls and ceilings across a whole project. Acacia Franc is traditionally used for panelling, floors and stairs, and Angélique for joinery. For something seldom seen, the Rare species are prepared to order.

Is there enough timber for a whole facade?

Yes. Around 9 million cubic metres of timber lie in the reservoir, and the Popular species are available in volume. Volume, grade and lead times are confirmed for each project at specification.

Why hasn't the wood rotted under water?

Below roughly five metres (about 16 feet), the reservoir is virtually free of oxygen, so the fungi that cause decay cannot work and the timber hardly degrades. Recovery focuses on the deeper areas; wood from shallow or fluctuating water decays and is not used. Each species and batch is still graded, dried and technically reviewed before use.

How is the origin documented?

Each batch ships with a Certificate of Guarantee of Origin, and the timber is harvested under a 25-year contract with the national forest office. That documentation can support BREEAM Mat 03 responsible-sourcing evidence; credits are confirmed by each project's assessor.

Do you supply projects in the US?

Yes. The collection is offered to projects in both the UK and the US. Start with samples or a presentation by video call; volume, grade, lead times and delivery are confirmed for each project at specification.

When can I order?

The collection is being introduced in the UK and the US now, with first projects delivered from 2027. Reservations for 2027 projects are open: request samples, book a presentation or download the catalogue.
