Why Choose Texas Buildmart?

At Texas Buildmart, we don’t just manufacture air vent covers, we solve real-world design and functionality challenges. We’ve worked in the construction industry since 2013, and we kept seeing homes get new floors, lighting and cabinets but keep the same stamped metal grilles from the 1950s. So in 2019, with feedback from the builders and contractors we’d worked beside for years, we set out to build a vent that looks like part of the room. That vent became our Standard Linear Slot Diffuser. Today we make standard linear slot diffusers in more than 70 sizes that fit right into the existing register box, plus linear slot diffusers in 1, 2 and 3 slots from 12 to 72 inches, matching plenum boxes and mud-in versions for a frameless, built-in finish. Everything is 100% aluminum with a powder-coated finish, ships from our warehouse in Tempe, Arizona, within one business day, and is trusted by HVAC contractors, builders, remodelers, architects and homeowners across the U.S.
