As a preferred vendor partner of Dunn Lumber, Western Building Products offers a broad portfolio of interior and exterior doors that consistently deliver on performance, craftsmanship, and customer satisfaction.

Their deep experience in millwork and commitment to quality materials make them a go-to supplier for residential and light commercial applications alike.
Built with Better Materials for Superior Performance
When you’re on the jobsite—or installing in your own home—you realize fast how much quality matters. Western Building Products uses high-quality, robust components to ensure doors maintain their integrity, style, and smooth function over time.
For interior doors, Western offers a variety of core options, including solid and hollow core designs. Their most popular interior lines include stile-and-rail construction using engineered lumber—often laminated veneer lumber (LVL)—which resists warping and twisting better than traditional wood. These doors stay square, true, and reliable, even in homes with varying humidity or temperature conditions.
For exterior applications, Western Building Products provides fiberglass and steel options that combine low maintenance with high durability. Their fiberglass doors are available with woodgrain finishes that mimic the warmth of natural wood but stand up to weather, moisture, and wear in ways real wood can’t. These doors are ideal for homeowners who want a premium appearance without the constant upkeep.
Western also manufactures steel entry doors designed for enhanced security, energy efficiency, and long-term use. With composite edges, injected polyurethane cores, and customizable panel options, these doors strike the right balance between function and style—something both contractors and clients appreciate.
What’s New: Design Trends & Product Innovations
Western Building Products consistently updates its offerings to match market demands, home design trends, and construction needs. Their latest lines on visual appeal and streamlined installation and compatibility with a wide range of hardware and opening types.
One standout product category is barn doors, which continue to grow in popularity in both rustic and modern interior spaces. Western’s barn doors come in multiple designs and finishes, from clean minimalist panels to traditional planked looks. These doors are ideal for space-saving room dividers or as an architectural focal point, and they’re available with optional hardware kits for smooth contractor installs.
Their interior molded panel door collection also offers a wide range of profiles and textures—from classic 2-panel square-top looks to more contemporary designs. Molded panel doors provide cost-effective solutions for multi-unit projects, light commercial work, or high-volume residential builds.
Western’s catalog includes flush doors, louvered doors, and shaker-style panels, giving contractors flexibility when matching architectural plans or responding to client requests. Their prefinishing options and custom capabilities also allow for shortened lead times and simplified jobsite coordination—another reason why pros continue to recommend the brand.
Designed for the Jobsite: Installation Made Easy

Contractors know that time is money—and doors that install cleanly and stay reliable reduce callbacks and boost productivity. Western Building Products considers the installer in every design decision, offering features that streamline every step of the job.
One example is their steel door units, which feature adjustable hinge pockets. This smart detail allows for easier adjustment during installation and ensures proper alignment. Instead of struggling to correct misaligned doors after hanging, installers can achieve a secure, flush fit with minimal effort.
Their fiberglass doors are also compatible with standard jambs and can be ordered as prehung units with weatherstripping and thresholds already in place. That means the doors arrive on-site w
ith everything contractors and builders need included and made to fit squarely into the rough opening.
Contractors working on large residential developments also benefit from the consistency of Western’s sizing and specifications. Because their products are manufactured with precision and tested to strict standards, there’s less variation between units—and fewer surprises during framing and finishing.
In addition, Western provides clear documentation and product data sheets to help contractors understand each door’s specs, recommended hardware, and finishing options. From the shop to the jobsite, their support makes a difference.
