5 Best Dishwasher Insulating Blankets That Are Easy to Install 

1. Reflective White Foam Insulation Heat Shield – Best Insulating Blanket Overall 

This insulating blanket is our top pick as it reflects more than 95% of the heat that your dishwasher produces and keeps your kitchen cool as it runs. You can easily cut this insulation with a utility knife or a standard pair of scissors to the size of your dishwasher.

Furthermore, you won’t have to fret about hazardous dust or nasty fibers spreading all over your space because this product is both non-toxic and mess-free.

2. Lynn Manufacturing Kaowool Ceramic Fibre Insulation – Most Attractive Blanket

Lynn Manufacturing Kaowool Ceramic Fibre Insulation is our next dishwasher insulation blanket.

It can resist temperatures of up to 2400o Fahrenheit, and while your dishwasher will never reach that temperature, it is useful to know how strong it is! 

However, because it can withstand far greater temperatures, it can pose its own risks. When installing this, you must wear a respirator, gloves, and safety eyewear as the little flying chips can potentially damage your eyes and lungs.

Benefits of a Dishwasher Insulation Blanket

Besides muffling the sound of the dishwasher, the dishwasher insulation blanket is useful for many other reasons. A few of them are:

Sound Absorption

An insulating blanket will assist to lessen the amount of noise produced by your dishwasher when it is in use. The spraying water, the drain, and the buzzing of the dishwasher elements all influence the amount of noise that the machine creates throughout a wash cycle. This sound is considerably diminished when using an insulating blanket. Because of advances in sound-dampening technology, it is now feasible to run the dishwasher without disturbing any conversations.

Heat, Steam, and Water Protection

The dishwasher may become excessively hot during a wash cycle. This is due to the fact that the machine utilizes hot water throughout each cycle. The heat, along with the steam and water from the dishwasher, can harm the nearby wooden pieces as well as the floor. A protective barrier provided by an insulating blanket surrounding the dishwasher helps to lessen the impact on the surfaces.

Vibration Reduction

When the dishwasher is in operation, it is usual for it to vibrate. Wrapping an insulating blanket around the machine will assist it to stay in place. You may also add insulation to the doors to prevent the front from rattling as well. 

Dishwasher Insulation Blanket Buying Guide

The wide variety of options available in the market may confuse the uninitiated when shopping for dishwasher insulation blankets. Our buying guide will ensure you find your perfect match.

Things to Consider

The two things that matter the most while buying a dishwasher insulation blanket are:


Make certain that the insulating blanket you intend to buy will fit your dishwasher adequately. Built-in dishwashers are often designed to fit exactly, leaving little room for extra insulation. Move the dishwasher from its location and take measurements of any extra space before purchasing an insulating blanket.

Pro Tips for Installing Insulation Blankets

Soundproofing your dishwasher is a simple task that you can complete quickly. Here’s a simple tutorial to help you figure out what you need to do.

Step 1: Turn off the Dishwasher

While the dishwasher is still hooked to the power and water pipes, you cannot work on it. So ensure you use a wrench to tighten the water valves before removing all the other lines.

Step 2: Take the Dishwasher Out of the Cabinet

Find the screws that hold the dishwasher to the countertop to determine where it is fastened to the cabinet. To remove the dishwasher from the cabinet, unscrew them. This may require some work, so an additional pair of hands may be useful.

Step 3: Remove the Old Insulation

You will need pliers to remove the old insulation. This will aid in the removal of the rivets that keep the insulation in place. When doing so, take care not to harm the rivets, which will be used to secure the new insulation.

Step 4: Replace the Insulating Wrap

Simply fit the new insulation over the dishwasher and secure it using rivets and pliers.

Step 5: Replace the Dishwasher

Once you’ve finished insulating your dishwasher, all that remains is to reattach it to the cabinet. Before putting the dishwasher back into position, make sure the power and water lines are properly reconnected.
