SIDING/EXTERIOR TRIM

THE FACE OF THE BUILD

Siding sets the character of a structure. Exterior trim gives it definition. Montana-milled and Montana-finished, Glacier Millworks exterior wood products bring natural warmth, lasting craftsmanship and a distinctive finish to residential and commercial projects.

From species and profile to texture and finish, every detail is considered for the demands of the application and the vision behind the project.

Built for Exterior Performance

Exterior wood has to do more than look beautiful on day one. Species, finish, profile and installation all play a role in how siding and trim perform in sun, moisture and changing seasons.

At Glacier Millworks, we bring those decisions together to create exterior wood solutions tailored to the project.

The Right Species for the Application

Every project brings different conditions. We help match the species and product to the application, exposure and desired aesthetic, balancing natural character with the performance demands of the project.

Finishes Made for the Elements

Our exterior finishes are selected and applied with exposure in mind, helping protect the wood while bringing out the depth, grain and character of the material. Depending on the species, finish and exposure, wood can retain its original character or gradually develop a natural patina over time.

Installed with Care

Proper installation plays an important role in long-term exterior performance. Acclimation, fastening, spacing, ventilation and drainage should be considered based on the product, profile and project conditions.

Ready for a Lasting Install

Giving each board room to breathe, matching the fasteners to the profile and keeping air moving through the eave all help your fascia and soffit stay true for the life of the build.

Product Lines Built for the Exterior

Each of our product lines offers a distinct combination of performance, texture and finish. The right choice depends on the application, project conditions and the look you want to achieve.

Frequently asked questions

Which product line is right for exterior siding?

The right product depends on the application, exposure, performance requirements and desired aesthetic. Glacier Millworks offers a range of exterior options, including artisan-finished and thermally modified wood. Our team can help you compare species, finishes and performance characteristics to determine the best fit for your project.

How do you match the right species to climate?

Wood species perform differently depending on moisture exposure, UV intensity and temperature swings. We account for these conditions while keeping your project's application and finish requirements in mind, working directly with architects and builders to land on the species and treatment that will hold up long-term.

Will the finish keep its color outdoors?

Exterior wood naturally changes with UV exposure and weather. The species, finish, exposure and maintenance all influence how its appearance evolves over time. Our team can help you select a finish based on your project’s appearance and performance goals.

 Can I request a custom profile or finish?

Yes. We custom-mill and finish products in-house to meet project-specific requirements, with options for custom profiles, sizes, textures, finishes and colors depending on the product.

Do you ship beyond Montana? 

Yes. Our products are milled and finished at our Montana facility and shipped to residential and commercial projects across the country.
