Boat Engine Compartment Insulation Kit

* Made In USA*


Second Skin Boat Insulation Kits have all the materials you need to annihilate unwanted engine noise and get back to relaxing on your boat. No more yelling required when friends and family need to SIT DOWN or GRAB THE ROPES the next time you idle your way up to the dock. Get ready to enjoy the peace and quiet that only a massive reduction in engine noise can bring.


Our #1 boat engine compartment kit is "The Doghouse Kit."  It's specifically designed for a boat with a fiberglass doghouse. Start with a layer of Damplifier Pro to stop the structural noise due to the doghouse vibrating. Use the foil tape to seal the seams and protect from water. Finish off with a layer of Heat Wave Pro to absorb and muffle the engine noise. Results range from 5 to 10 dB reduction depending on the compartments construction and how much material you use (30-50% of perceived noise). Pretty awesome for a project that takes a couple hours.


If your engine compartment is in the back of the boat and you need to replace insulation that's coming apart or falling down, you should be looking at Mega Block instead. Mega Block is an aerospace grade hydrophobic melamine foam coated with a 1000°F heat shield. It's bendable, but easiest to install on the flat surface of the engine compartment lid. Tape the seams with foil tape to protect the material.

Boat Doghouse Insulation Kit

Damplifier Pro Install Guide

These same materials can be used as RV engine compartment insulation for your RV's doghouse. 


Step 1: Damplifier Pro on the Fiberglass Doghouse

Clean the doghouse with denatured alcohol. Don't use degreaser or any cleaner that will leave a film behind, because it will negatively impact the mat's adhesion. Just cut, peel, and stick. It's easiest to cut any holes after you install the material. Damplifier Pro will stop the structural vibrations of the compartment itself to reduce noise.



Step 2: Foil tape the seams

Adding foil tape on the seams adds extra protection. Not required, but recommended.



Step 3: Heat Wave Pro as your insulator and sound absorber

Heat Wave Pro adds some much needed sound absorption to help further reduce engine noise. Think of your engine compartment as a box with sound reverberating around inside it. With Heat Wave Pro absorbing those sound waves instead of them bouncing off the hard surface, you have less build up and less overall noise escaping.
