    Good quality - hemmed and seamed edges on the bottom. Closest thing I could find to what I needed but I've had to modify by cutting the height in half for my application and re-forming the top of the boxes. (they are located at doors/windows at the low part of the roof line)

    I am trying to find the proper CFM for a 12" vent cover I have in my living room but I don't know where to start
    1 year ago
    The CFM, or Cubic Feet per Minute, refers to the volume of air exchanged in a room per minute. It's calculated by dividing the room's volume by the air changes per hour. On average, a typical room undergoes around 7 air changes per hour. This figure is dependent on how often the air is recycled back to your return.

    Do these diffuser allow lower noise criteria? Or will it be the same as regular vents.
    1 year ago
    Hello there, Thank you for contacting Texas Buildmart. Our linear diffusers and standard units will provide a similar level of airflow as your CFM requirement. For instance, our linear diffusers can match the maximum airflow of your current 10x6 traditional vent cover, with the added advantage of enabling better air diffusion. For any further queries, feel free to reach us directly at (956)900-1103. Thank you.

    I want to know the difference so I know what to buy, do I need a standard diffuser or a linear diffuser to exchange from my old traditional vent covers.
    1 year ago
    Greetings, Thank you for your inquiry at Texas Buildmart. Our Modern AC Vent Cover has unique attributes compared to standard diffusers. Our linear diffuser's slender design offers a modern aesthetic while also providing superior airflow. It's streamlined, allowing for a 180-degree airflow spread, a feature that surpasses standard diffusers' 90-degree limitation. Additionally, our standard diffusers come pre-fitted for standard sizes, enabling a straightforward replacement process. If you seek a sleek, efficient diffuser, our Modern AC Vent Cover is an excellent choice.

    On the website it shows the measurements of the inside and outside dimensions.
    It doesn't show the depth of the vent cover, could you tell us the depth of the vent cover?
    Thank you.

    1 year ago
    Greetings, Thank you for your inquiry with Texas Buildmart. The depth of our linear and standard vent covers is uniformly measured at 1 3/4". This measurement spans from the top faceplate to the bottom of the vent neck. Should you require further information or have additional questions, please don't hesitate to ask. We're always here to assist you!

    Can the screws be shown when ever it is installed since it doesn't show on the images of the product.
    1 year ago
    Hello and thank you for contacting Texas Buildmart. To answer your query, the screws of the product are indeed invisible post-installation. This is due to the holes' strategic location on the side of the diffuser. This design choice ensures a clean, modern aesthetic for your installation.
