  • Dampen Sound

One of the best functions of an insulation blanket is it lessens the noise being made by your dishwasher while you are operating it. A wash cycle is pretty complex process that involves spraying of water, draining of water, the spinning and humming of the dishwasher parts. All of these play a role in contributing to the noise that your machine creates.

If you put an insulation blanket around the exposed parts of the washer and those hidden in the cabinet, its sound is significantly reduced. The advent of technology has paved the way for these awesome sound dampening devices that will make your machine ultra quiet. This ensures that you are not distracted from your tasks and your conversations are not interrupted.

  • Protect Against Heat, Water, and Steam

When your dishwasher is under its wash cycle operation, the whole unit can get hot. This is due to the ultra hot water used by dishwashers that serves to remove dirt, oil patches, and germs on your plate. Remember, your saliva has a lot of living bacteria that you pass onto your dinnerware and cutlery every single time you eat.

Since your dishwasher is typically encased in a cabinet underneath a countertop, it can get super hot enough to damage the wooden parts of your kitchen counters, including the floor. The steam and the damp moisture coming from your dishwasher are also contributory factors.

If you put an insulation blanket around your dishwasher, all these problems will be addressed without much fanfare. Place it around the dishwasher, so it will act as a protective barrier.

  • Reduces the Vibrations

Because the parts within the dishwasher are constantly moving, it is quite common for all dishwashers to vibrate. As it moves, it creates an echo in between the cabinets where it is installed, so the sound tends to spread.

Having an insulation blanket will absorb the noise and prevent the sound waves from traveling far. Placing this material in front of the door will also prevent it from rattling too much as the machine is operating.
