Benefits of AWV Architectural Louvers
AWV architectural louvers are designed with aesthetics in mind
Reduced Energy Costs
AWV’s louvers are highly aerodynamically efficient. The low air resistance reduces the fan energy required to introduce the ventilation air into or exhaust air out of the building.
AWV louvers are available in a wide variety of shapes, sizes, materials, finishes and coatings to meet the requirements of any project.
AWV can provide certified structural calculations when requested to ensure louver structural integrity. All architectural louvers are constructed of aluminum.
Enhanced and Proven Performance
AWV louvers are both efficient and have a remarkably high resistance to water intrusion. Our louvers have been completely tested for air performance and water penetration. AWV is a member of the Air Movement and Control Association (AMCA) and our product performance is AMCA certified.
