Extract air is then pushed horizontally out of either side of the grille and slotted louvred vents. This ensures weatherproofing and reduced noise without the need of a mechanical shutter or noisy back draft flap.Īs an air extract vent, expelling dirty air from a heat recovery system, bathroom extractor fan or kitchen cooker hood, air passes over an airflow splitter and noise dampening liner. Air also passes over a sound adsorbing lining to dampen airborne noise. When used and an air intake vent serving a heat recovery system (MVHR), positive input ventilation (PIV), mechanical extract system (MEV) or single room heat recovery unit, air is drawn in from opposite sides of the vent through louverd vents. The Blauberg AH-10 vent cover will flush fit to an external wall and will also accept a 100, 125, 150 or 160mm diameter duct depending on which size you order. They look great, reduce internal and external noise, and are easy to fit onto any external wall. To further improve the effectiveness of this technique, apply acoustic foam to the interior of the cover using green glue to secure it in place.A brilliantly designed external wall vent that meets the needs of any ventilation system. Since there aren’t any openings, it’s harder for soundwaves to escape.
AIR VENT COVER WALL INSTALL
Standard air vent covers are louvered however, you can purchase solid covers that do not feature any openings and install it over the existing cover of the air vent. For even more soundproofing, apply weather stripping tape around the interior edges of the air vent cover. Use adhesive (we recommend green glue) to secure the plywood to the interior of the vent cover.
Cut a piece of plywood so that it’s a little bit smaller than the back of the air vent covers.For even more soundproofing power, apply another layer of materials to the exterior of the vent. Use an adhesive glue to secure the material to the interior of the vent. Cut the material so that it’s the same size as the interior of the vent. Hang soundproofing material over the air vents.Some of the different options that we recommend include: There are several ways that you can block up your air vents to create a soundproof barrier. Lastly, if you really want to soundproof your air vents and you don’t mind if they no longer function, you can block them. Apply acoustic foam to the back of the air vent, using green glue to secure it in place.
The panels should be attached to the interior of the vent in an alternating fashion, for example, the first one on the left side, the second one on the right side, the third one on the left side, and so on. Secure the plywood piece in place by applying glue to one edge and slipping them into the air vent, leaving about an inch of space between each one.Attach acoustic foam to both sides of each piece of plywood using green glue.Create a minimum of four plywood pieces of the same size. Cut the plywood so that it will fit inside the vent, and then cut around 30% off of the end of the wood so that air can travel around it.However, while it’s effective, creating a sound maze can be a bit labor intensive. As such, the amount of noise is significantly reduced. That’s because the maze creates several surfaces within the vent, and the soundwaves will need to bounce off of those surfaces in order to enter into your room. A sound maze won’t prevent air from flowing through the vent, so ventilation won’t be an issue, yet it successfully deadens unwanted sounds. Attach the foam to the covers, ensuring that all gaps are covered.Ī sound maze is one of the most effective soundproofing techniques for an air vent.Apply adhesive along the edges of the interior of the covers.Cut the acoustic foam so that it’s the same size as the vent covers.Remove and measure the air vent covers.To soundproof your air vents with the material, follow these simple steps: Therefore, this material can absorb the echoes that pass through the vents, thereby minimizing the amount of unwanted sound that’s traveling into the space you’re trying to soundproof. The sound quality in a room hence why acoustic foam is commonly usedįor air vents, acoustic foam can prove to be an effective way to reduce noise because these structures tend to generate a lot of echo this is particularly true if they’re constructed of metal.
Intended to block out noise, but instead, it’s designed to enhance Preventing them from creating an echo-effect.
As soundwaves bounce through the air, the foam picks them up,
