Our Green Outlook:
Flannery has been well represented for years by the Green Shamrock in its logo. It is a symbol for our company and a reminder of our commitment to being more "Green". We are fully engaged in the "Green" movement that is taking place in the construction industry. We are committed to implementing new ways to run our manufacturing plant that are more environmentally responsible. Our goal is to produce products that are viable and sustainable for the future of our industry and our planet.

Flannery has manufactured aluminum, steel, and vinyl trims for the drywall and stucco industries for over 30 years. Since our founding in the late 70's, we have recycled our scrap and leftover materials from the production process in an attempt to reduce the cost of doing business as well as its impact on the world around us. We are thrilled to be a manufacturer of aluminum trims knowing full well the benefits of a product that can be recycled once its intended purpose comes to an end. Flannery looks forward to its continued relationship with our "Green" vendors and customers who look to reduce the environmental impact our industry has on the world.

Exterior Trim

Flannery Trim offers a number of different trims for exterior wall systems. While the majority of these trims are aluminum extrusions we do manufacture a few in vinyl and various metals. The types of exterior wall systems that we provide products for include exterior plaster/stucco, fiber cement panels, composite siding and soffits/ceilings. Here is a breakdown of each category:

Aluminum Plaster Trim

Flannery Trim boasts one of the most extensive product lines of aluminum plaster and stucco trims. We offer just about every kind of shape for a plaster wall from the smallest of Channel Screeds to largest of Window Returns. These types of aluminum extrusions can trim out corners and walls where a decorative effect is desired. Having specialty trim can make all the difference on a large scale commercial project.

Cement Panel Trim

Fiber cement panel trims continue to be one of Flannery’s fastest growing product lines. While fiber cement panels have become the norm in outdoor applications throughout the Northwest, the trend to use them in both commercial and residential construction has continued to move into several other climate zones. We offer horizontal and vertical reveals, along with the various other trims to complete the design configurations where cement panels come together and the need for trim is apparent.

Composite Siding Trim

Our Composite Siding Trims were specifically designed for the TruGrain siding products, however they can be used with any number of siding materials where panel expansion and contraction is a concern. These aluminum siding trims come in a number of different styles and shapes, and are designed to fit into a wall assembly seamlessly. Composite siding enables a building to stand out and Flannery’s Siding Trims enhance that creative style.
