Frequently asked questions

What does Ash Thermowood offer compared with other woods?

[A validar] A deep tone and a pronounced grain, with the stability of thermal modification. It is prized for decks and cladding with high aesthetic demands, where a dark, uniform finish is wanted without stains.

What is Thermowood?

[A validar] It is thermally modified wood: treated with heat and steam at high temperature, with no biocides added in that process. The result is a more stable wood, with less movement and greater resistance to moisture and fungi, suitable for outdoor use in a tropical climate.

How is a Ash Thermowood deck installed?

[A validar] On a frame with supports every 40 cm, with stainless-steel screws or hidden clips, and 2 to 7 mm gaps between boards. Leave at least 10 cm of ventilation underneath. Professional installation is key to its durability, stability and performance in a tropical climate.

How often should Ash Thermowood be maintained?

[A validar] Outdoors, every 1 to 3 years; indoors, every 3 to 5 years, depending on sun and rain exposure. The MadeiraTech catalog recommends oils such as Special Wood Oil or CUTEK Extreme Oil. An advisor will tell you which product and how much for your surface.

How do I order Ash Thermowood?

[A validar] In four steps: we confirm availability, define the specifications (profile, dimensions, finish), send you the quote with the cutting list, and you confirm the order. Message us on WhatsApp with the use and approximate area, and an advisor guides you from the first step.
