Choose Your Avara™ Grade
Choose the appearance and grade that suits your project.
The Avara™ grades are carefully selected to balance visual character, structural properties and project requirements.
Clear
Selected for their natural flatsawn grain and virtually knot-free appearance. Avara™ Clear works particularly well with profiling, texturing and Yakisugi finishes, where the grain and movement of the timber become more pronounced.
Character
Thermally modified Finnish Spruce featuring visible knots and pronounced natural variation, offering a more expressive timber aesthetic. This grade offers a more expressive timber aesthetic while still delivering strong exterior performance and dimensional stability.
Why choose Avara™
Avara™ is Corell’s thermally modified timber system, developed for architectural applications where material consistency, finish quality and long-term exterior performance matter.
Through a controlled heat and steam process, the timber is modified to improve dimensional stability without chemical preservatives.
Manufactured in Ireland, Avara™ allows full control over profile, texture and coating finish — giving architects and builders a more consistent and reliable cladding material across both standard and bespoke projects.
Avara™ is supported by a 15-year limited warranty against fungal decay when correctly detailed, installed and maintained.
Why Not Composite?
Composite cladding is often selected for perceived low maintenance, but as a plastic-based material it behaves very differently to real timber and presents limitations at end of life due to its mixed material composition.
Avara™ thermally modified timber offers improved dimensional stability with a surface character and natural variation that cannot be replicated by composite alternatives.
As a solid timber product, Avara™ can be repaired, reused, recycled or allowed to biodegrade naturally at end of life.
For projects where material authenticity and long-term appearance matter, real timber remains the preferred solution.
Irish Made
Fully In-House
Built For Better Projects
Every cladding profile, texture and finish is produced entirely in-house, allowing greater control over quality, consistency and lead times.
By machining and finishing in Ireland, Avara™ maintains a closer connection between design intent, manufacturing and final installation.
Shape the Look —
Protect the Wood
Corell’s range of colours, textures and coating systems allows Avara™ to achieve different architectural outcomes while retaining the natural character of real timber.
From subtle weathering finishes through to darker textured coatings and Yakisugi surfaces, each finish is designed to work with the timber rather than conceal it.
Stores Carbon
No Chemicals
Fully Recyclable
Avara™ offers a renewable alternative to many slower-growing hardwood and old-growth timber species.
Because the timber is thermally modified rather than chemically treated, it remains fully recyclable at end of life while continuing to store biogenic carbon throughout its service life.
Enhanced Fire Performance
Avara™ Clear and Avara™ Character can be supplied with pressure-impregnated fire-retardant treatment for projects that require enhanced fire performance. This process results in a Euroclass B-rated timber while maintaining the timber’s natural appearance and dimensional stability. Please contact our technical team for specification guidance and minimum order quantities.
Frequently asked questions
Avara™ is produced from thermally modified Radiata Pine and Finnish Spruce sourced from responsibly managed forests. Through a controlled heat and steam process, the timber is modified to improve durability and dimensional stability without chemical preservatives.
Avara™ is designed for long-term exterior use when correctly detailed, installed and maintained. Thermal modification improves resistance to moisture movement and fungal decay, making the timber well suited to exposed façade and screening applications.
Yes. Avara™ can be supplied untreated or factory finished depending on the intended appearance and maintenance approach. Coatings can be used to introduce colour, slow weathering, or create a more controlled finish across the façade, while untreated timber will naturally silver over time.
All timber moves naturally in response to environmental conditions. Thermal modification significantly reduces moisture movement, resulting in improved dimensional stability and more predictable behaviour compared to untreated softwood.
Avara™ is produced from responsibly sourced timber and modified using heat and steam rather than chemical treatment. As a solid wood product, it remains recyclable at end of life while continuing to store biogenic carbon throughout its service life.
Avara™ Clear and Character can be supplied with pressure-impregnated fire-retardant treatment for projects requiring enhanced fire performance. Euroclass B systems are available subject to profile, fixing method and project specification requirements.
Avara™ can be installed using either visible or concealed fixing systems depending on profile selection and design intent. Stainless steel fixings are recommended for exterior use, along with correctly ventilated cavity construction and appropriate detailing around openings and junctions.
Yes. Avara™ can be charred using the traditional Yakisugi process, then brushed and coated to achieve different surface textures and visual effects. The final appearance can range from lightly textured finishes through to heavier “gator skin” style charred surfaces.
Maintenance requirements depend on the selected finish and level of weather exposure. Untreated timber can be allowed to weather naturally, while coated finishes may require periodic inspection and maintenance coats over time to retain a more consistent appearance.
Expert View
“Avara™ developed from years of working with architects, builders and homeowners looking for a timber cladding material that performs reliably in Irish conditions while still retaining the character of real wood.
The focus has always been on producing a more consistent architectural timber system — from machining and texture through to coating and finish.”
