Colour options, shaped by the material

Timber brings warmth, depth and natural variation to architectural glazing. Our finishes protect that character and help every frame sit naturally within the building.

Surface collection

Glazing should feel part of the architecture around it

The materials we choose define the character of a building. They influence how light enters a space, how surfaces are experienced, and how architecture matures over time. Few materials possess the warmth, depth and authenticity of timber. Every grain pattern, subtle variation in colour and natural marking creates something entirely individual.

At Ecovia, we believe glazing should never feel separate from the architecture around it. Instead, it should become part of the material palette itself – integrating structure, light and craftsmanship into a single expression. This guide explores the timbers, finishes and coating technologies that define the Ecovia collection, explaining not only the colours available, but the thinking and engineering behind every surface.

Our material approach

Natural timber for contemporary architecture

Timber has been used in architecture for centuries, yet its relevance has never been greater. As designers increasingly seek materials with lower embodied carbon and greater authenticity, timber offers a rare combination of sustainability, performance and beauty. It is renewable, naturally insulating and inherently warm to the touch, while modern engineering allows it to perform at the highest architectural standards. Unlike synthetic materials, timber evolves over time. Changes in grain, texture and tone create subtle variations that bring individuality to every project. No two pieces are ever identical and that uniqueness is one of its greatest strengths.

  • Warm and tactile
  • Lower embodied carbon
  • Strong thermal insulation
  • Repairable and renewable
  • Made for clean detailing
  • Built for long service

Our timber collection

Five species. Five distinct characters.

The choice of timber has a significant influence on both the appearance and long-term performance of a glazing system. Each species offers its own grain pattern, density and natural character, allowing architects and designers to select the material that best complements the project.

At Ecovia, only carefully selected engineered timbers are used, delivering exceptional stability and consistency while preserving the beauty of the natural material.

Pine

Pine

Warm and versatile, with a straight grain and an even appearance. A strong choice for painted and light stain finishes.

Pine remains one of Europe’s most widely used construction timbers. Its clean grain and consistent appearance make it particularly well suited to painted finishes and contemporary detailing requiring light stains.

Engineered pine offers excellent dimensional stability while providing our most economical solution for glazing.

Ideal for:

  • Painted finishes
  • Light stain finishes
  • Cost-conscious specifications
Spruce

Spruce

Light in colour with fine grain. Its insulating qualities suit Passivhaus and low-energy projects.

Spruce is characterised by its pale colour and fine grain structure, creating a smooth and contemporary appearance that works particularly well with lighter to medium-dark stains and some natural finishes.

Its density makes it the timber most suited to Passivhaus and low-energy applications.

Ideal for:

  • Scandinavian-inspired interiors
  • Light to medium-dark stains
  • Passivhaus and low-energy builds.
Oak

Oak

Oak is chosen not simply for its performance, but for its presence. Its rich grain, natural warmth and unmistakable character allow it to become an integral part of the architecture itself. Rather than disappearing into the background, oak rewards thoughtful detailing and works best where the glazing is intended to be a defining feature of the building.

Whether paired with exposed concrete, natural stone, polished plaster or contemporary brickwork, oak provides a softness and authenticity that balances more industrial materials. As light moves across its surface throughout the day, the grain and texture continue to reveal new depth and character.

Ideal for:

  • Feature glazing, where the frames are intended to be seen, not hidden
  • High specification projects combining natural and modern materials
  • Locations requiring durability as well as visible timber character
Larch

Larch

Durable and rich in character, with a warm reddish tone that works well when the timber remains visible.

Larch is valued for its expressive grain and naturally warm colouring. Its higher density and durability make it particularly suitable for external applications where the natural beauty of the timber is intended to remain visible.

Over time, larch develops additional depth and richness, complementing both traditional and contemporary architecture.

Ideal for:

  • Natural finishes
  • More exposed locations where durability is a concern
  • Projects celebrating visible timber character
Accoya

Accoya

Modified for low moisture uptake, strong stability and long service life in exposed or coastal locations.

Accoya represents one of the most advanced timber technologies available today. Through a process known as acetylation, the timber’s cellular structure is permanently modified, dramatically reducing moisture absorption and improving dimensional stability.

The result is a material with exceptional durability, minimal movement and outstanding long-term performance, making it ideal for demanding architectural environments. We use an engineered section of Accoya and pine or spruce in combination.

Ideal for:

  • Coastal and highly exposed locations
  • Dark stains or colours
  • Lowest possible maintenance specification

Crafted to last

A finish starts with the timber

Exceptional finishes begin long before the first coat is applied. Every piece of timber is carefully prepared and conditioned before entering the finishing process, ensuring optimum moisture content and long-term dimensional stability.

Surface preparation, coating application and final inspection are all carried out under tightly controlled manufacturing conditions, producing a finish that is both highly durable and visually refined. The result is a surface that enhances the natural beauty of the timber while providing long-term protection against the demands of everyday use.

Consistency cannot be achieved by hand alone. Every timber component is scanned using laser technology before entering the robotic coating process. Precision spray systems ensure an even application across every profile, edge and detail, producing a remarkably consistent finish. Intermediate sanding is carried out by hand to ensure surfaces are smooth to touch.

Each component receives four separate coating applications, resulting in a surface quality that combines the refinement of fine furniture with the durability required for architectural glazing.

The finish collection

Designed around the material

A finish changes how timber responds to light, how much grain remains visible and how the frame will mature. Choose a range to compare the available surfaces.

Discuss this finish

Screen colour is a guide only. Timber grain, tone and texture vary from piece to piece. We recommend approving a physical sample before the finish is confirmed.

Bespoke colour

Colour without compromise

While our carefully curated collection has been developed to suit the vast majority of architectural projects, we recognise that some designs demand something more individual.

For projects where colour plays a defining architectural role, Ecovia can supply bespoke finishes matched to virtually any recognised colour standard, allowing glazing to integrate seamlessly with the wider material palette.

Whether coordinating with brickwork, cladding, natural stone, interior joinery or existing architectural elements, bespoke finishes provide complete design flexibility without compromising the performance of the coating system.

Every custom finish is produced using the same multi stage coating process as our standard collection, ensuring exceptional durability, colour consistency and long-term weather resistance.

If your specification requires a unique finish, our technical team can advise on colour matching and system compatibility during the design stage.

Care and specification

Designing for exposure

  • The longevity of any timber finish depends not only on the coating itself, but on the architectural detailing that protects it.
  • Deep reveals, generous roof overhangs and recessed installations naturally reduce weather exposure, helping preserve the appearance of the timber over time.
  • More exposed coastal locations or elevations subject to prevailing weather may benefit from more durable timber species or finish selections.
  • By considering exposure during the design process, architects can ensure their glazing systems continue to perform beautifully for decades.

Looking after timber

Simple care for a long service life

Routine cleaning and a visual check help keep the finish in good condition. If minor damage occurs, timber can be repaired and refinished locally instead of replacing the complete frame.

  • Clean gently
  • Inspect the coating
  • Repair small marks early
  • Follow project care advice

Understanding your sample

Every sample tells part of the story

Each sample represents a natural material. Colour, grain and texture can change across the frame, which is part of the character of timber.

Oak and larch samples


Every sample includes information relating to:

  • Timber species
  • Finish name
  • System compatibility
  • Price group

Understanding natural timber

  • Grain and colour variation are inherent characteristics of the material. Knots and natural figuring may be visible depending on species and finish.
  • Longer profile lengths may incorporate visible finger-jointed sections to enhance stability and performance.
  • These natural and engineered characteristics form part of the authenticity of real timber and should not be regarded as defects.
