How to Build a Soundproof Box for a Generator

Regardless of your generator’s brand or size, sometimes we reach a point when we feel the noise is too much. In this case, building a soundproof a box for a generator is an excellent way to reduce the noise for our generators.

The good news is we can build this cheap soundproofing box right from our home. In the article, I have reviewed all necessary and useful steps to create an effective and reliable soundproof generator box successfully. This will make you forget about generator noise and give you a calm environment when using it.

What you need

Before getting into specific materials we need for the above project, please understand the below couple of terms:

(a) Mass Loaded Vinyl will be the first layer of the soundproof generator box right from the bottom.

(b) Ventilation ducts – you will use these ducts to create an amazing airflow and supply for your soundproof generator box.

(c) Medium Density fiberboards – it is a primary fabric used to make this soundproofing box.

(d) Green glue- An essential item utilized for gluing the box edges down and also soundproofing tool

(e) Foam mats – this is another layer vital layer used to soundproof your generator box.

The requirements

(a) Pen and paper

(b) A saw ( table or circular)

(c) Measuring tape

(d) Right-angled ruler

(e) Glue

(f) Foam mats

(g) MLV

(h) MDF boards

(i) Vents

(j) Hammer and screwdriver

(k) Ventilation duct

(l) Acoustic Caulk ( e.g., the green glue)

Build a Soundproof Box for a Generator In 9 Easy and Reliable Steps

Step 1: Take accurate measurements

Before you start, remember a generator is built –up with different sizes. Thus a soundproof generator box goes in the same category. Besides, first, take the exact measurements of your generator before taking box measurements. In this case, be attentive since you might go wrong with every step of creating a generator box if you may mistake such dimensions.

Once you have gotten the accurate measurement, ensure you jot them down in a specific place. Add few pinches to every side since you will need a space for insulation and vents thickness. Then write down the last measurements and start creating your generator box. Tip: measure three or two times before cutting the box.

Step 2: Cutting the box

Use the medium-density fiberboards to get ready for the cut. In this case, the MDFs are helpful since it is good for soundproofing. However, if you don’t have considered utilizing the ordinary plywood, with a little less effective soundproofing than use fiberboard.

When marking your MDF dimensions, using a right –angles ruler and pen will help you get precise measurements. Triple or double-check your job and get ready for cutting. At this point, use a table or preferably a circular saw to cut your board. Further, ensure that you pay close attention to board measurements and labels which you made previously.

Step 3: Drill ventilation holes

Use a ventilation duct for this specific project and measure the length. Besides, this is the right time for measuring the fiberboard:

(a) The top mark should be positioned on the (ceiling) top of your box. Further, you will need to eventually place the specific circle closer on one side, preferably in the center of your boards.

(b) Secondly, place your second circle on one of your boards designed to be a wall (side) piece. Remember to mark such a circle on the other side right from where the top hole is positioned.

Once you have marked everything as directed comprehensive instructions, consider laying down the “walls” on the table, specifically placing the top “ceiling) in the middle with other “walls” around it.

Step 4: Adding MLV insulation

soundproofing layers is essential, and this is among the first thing someone should always remember in such a procedure—the layers of free space sound gaps, layers of fabrics, layers of everything. The only effective and durable material to utilize for soundproofing is MLV insulation.

Essentially, this is the primary layer that someone will utilize to build the soundproof generator. In this case, the first you need to do is measure the specific pieces of the MDF you cut out for your box. Following the same size, cut this MLV, gluing it right down directly to the soundboards’ inside side.

Step 5: Caulk the first layer of the insulation.

In some cases, the MLV edge insulation may be challenging to glue down appropriately. And a result, you will need to utilize the green glue to solve this problem.

Step6: Glue the foam rug down

Foam mats are meant to drastically lower the noise of the generator in your specific generator box. And what you will need is to add this layer to your ceiling and walls of the soundproof box. Further, you require taking care of the rugs you have when labeling your ceiling and walls’ dimensions and cutting them rightly. Additionally, glue your mats down on MLV top, repeating the similar process with edges using aa green glue.

Step 7: Put your box together.

Now assemble your box walls around with ceiling, screw, or nail them into place. Besides, you can specifically install some hinges to ensure easy access to the generator.

Step 8: Install vent duct

Put the vent hoses to specific holes you create in step three. And ensure you tighten them to place since you don’t them being loose and jumping around. At this point, the last touches of this soundproofing generator box will be adding a little vent above the openings. Once you have completed the above steps, you have your soundproof generator box ready to use.

Step 9: Color your box using paint

Besides, this is a simple but essential step. Many of us think that you don’t require insulation on the outer side, but the total truth is you hugely require it. The soundproof paint tends to absorb vibrations and block the noise. And this plays an essential part in controlling unwanted noise. Eventually, this should be the last step of building your soundproof box.

Conclusion

At this point, you will have successfully built your homemade soundproofing enclosure. And you will have solved the big problem of a noisy generator in an affordable and easy process. Please, follow the above comprehensive steps to ensure you have included every instruction in building your generator soundproofing box. Good luck
