Louvers are intended to protected openings in the external envelope of a building while allowing the structure to let air in or out depending on the design. Louvers can enhance a building's architectural look and meet ventilation air movement requirements. Whether a project specifies intake or exhaust, louvers come in a wide variety of blade styles, frame styles and materials that are all dependent on their application. Most louvers are manufactured from extruded aluminum since they brave the elements, however formed steel louvers can be made for applications needing custom gauge metals and stainless steel. The wall louvers can de designed to fit Metal buildings, CMU Wall, and Stucco to name a few. There are a wide range of finish options including galvanized, Kynar, baked enamel and anodizing.
The majority of today's standing seam roofs are manufactured from Galvalume-coated steel, which carries a 20-year corrosion warranty. Many projects today also require a 20-year weather tightness warranty.
Because roof curbs have become such a common accessory for standing seam roofs, it is essential that they too perform leak-free for 20 years. This requires building designers and roofing contractors to make some important decisions about the roof curbs they use.
Following are some critical areas to consider when selecting a product.
Roof walk systems are a highly overlooked rooftop product that needs to be discussed more frequently during project planning. Educating the building owner of a product that can prevent damage to their metal roof investment is in the interest of all involved parties. Either the architect / specifier can include roof walks on the initial bid documents / drawings, or the metal roof panel / building company can recommend roof walk under their warranty packages, or the roofing contractor can quote roof walk as an add during the bid process. Design build projects have a greater potential of having a roof walk system included on the project since the contractor and the building owner already have a close working relationship and the benefits can be explained directly.
