Sustainable timber, improved through thermal modification

Thermowood represents a carefully curated range of thermally modified timbers, selected for their enhanced stability, improved durability, and refined appearance. Through a controlled heat‑treatment process, each species develops reduced moisture movement and increased resistance to decay, resulting in a reliable, long‑lasting material suitable for both exterior and interior applications. From clear‑grade Radiata Pine and defect‑free African hardwoods to premium Finnish softwoods with strong environmental credentials, our Thermowood offering provides architects, designers, and builders with versatile, sustainable solutions that combine natural beauty with consistently high performance.

FAQ’s

Here’s everything you need to know before ordering our products.

The product I want isn't listed - is it unavailable?

We often source non‑stock items on request, so if you can’t find what you need on our website, it doesn’t necessarily mean it’s unavailable. Get in touch with our team and we’ll be happy to check availability or source it for you.

What is the minimum order?

Although we specialise in high volume requirements we can supply smaller quantities. Our minimum order is typically 6 packs for deliveries and 1 pack if collecting from one of our port facilities.

How quickly can you deliver?

Delivery lead times vary depending on the type and size of your order. As a general guide for stock items:

Part‑loads: up to 7 working days
Full‑loads: up to 3 working days

Bespoke items or deliveries direct from the mill will have variable lead times, which we’ll confirm on an enquiry‑by‑enquiry basis.

Do you offer nationwide delivery?

We deliver nationwide. Whether you need a full load or a part load, we can supply customers across the UK. If you have a specific location or delivery requirement in mind, just let us know and we’ll be happy to arrange it.
