When Wood Siding Failed, Architects Found a Solution: MAC Metal
Architects from 97w, designing a new ENT building in Clearfork, Fort Worth, initially selected reclaimed Brazilian hardwood for the exterior facade to achieve a distinctive modern aesthetic. Despite the wood's successful installations elsewhere and its anticipated aging process, the material failed within six months due to the harsh Texas weather. The wood siding exhibited separation of tight seams, discoloration, warping, popping nails, and structural instability.
Faced with this premature material failure, the architects sought a durable and visually appealing alternative. Their search led them to MAC Metal Architectural siding, located conveniently near Acme Brick's headquarters, which houses many construction experts. This change was crucial, as both aesthetics and long-term durability are critical considerations for commercial buildings.
MAC Metal Architectural provided a suitable replacement, allowing for the desired wood appearance without the associated maintenance issues. The product offers diverse aesthetic options, including six grain patterns and three wood tones, ensuring a natural, varied look. Installation involves 12-foot panels with a 6 1/16-inch lap exposure, concealed fasteners, and flexibility for horizontal, vertical, or diagonal application. The 'Harrywood' profile, specifically, was utilized in this project.
MAC Metal boasts a 25-year fade warranty and a 40-year product warranty, supported by a PVDF paint system. This system includes a zinc primer, two paint primer coats, and three top-coats on the exposed surface, enhancing durability against weather and UV rays. Steven Halliday, an architect from 97w, expressed initial frustration over the wood siding's failure despite thorough research and consultation. The Texas climate proved too challenging for the original material, making an alternative essential.
Strict materiality rules in Clearfork limited alternatives, but MAC Metal emerged as a strong contender, outperforming fiber cement and other metal products in terms of long-term maintenance. The MAC panels successfully replicated the warmth and varied appearance of wood siding while maintaining the original sightlines. The replacement process was straightforward, involving the removal of the old siding, inspection of the vapor barrier and sheathing, and installation of the new MAC panels without altering the overall wall profile. The project was completed in a continuous, six-month process.
Key benefits of MAC Metal Architectural siding include its maintenance-free nature, resisting brittleness, painting, and caulking needs, and preventing mold and mildew common with wood and vinyl. It is color-fast, featuring a MAC TEXTURAL Color System with a six-coat painting process that provides enhanced resistance to UV rays and corrosion. The product's matte finish eliminates glare and increases resistance to scratching and delamination. Additionally, MAC Metal is fire-resistant, potentially leading to lower insurance premiums, and comes with an industry-leading 40-year warranty when installed correctly. Environmentally, it is made from 100% recycled materials, contributing to LEED certification points.
