Can’t hear yourself think while on your boat?

Being out on the water gives you a sense of freedom and relaxation unlike any other… but you have to admit that it’s somewhat ruined by the constant noise of the engines. Fortunately, soundproofing your craft is easier than you think, and it has other benefits too.

We offer a product that not only cuts down on the ambient noise produced by your boat but also improves thermal insulation and adds buoyancy to give you greater peace of mind.

Enjoy better safety and comfort with this Liquid Urethane foam kit by TRUE COMPOSITES!

Our liquid urethane foam kit is the ideal choice for marine applications, and you can easily shape it to fill any void in your ship. It is a lightweight, powerful substance that adds extra buoyancy to your boat’s floatation chambers or even your docks, keeping them afloat no matter what.

Block sounds and maintain a comfortable temperature inside your boat with this insulating flotation foam! Our urethane also has a 95 to 98% closed cell structure once it has finished curing, making it immune to damage from gasoline, oil, fresh or saltwater, or solvents.

This pourable urethane foam cures rapidly, after which you can carve or sand it into shape. It can even be coated with any type of polyester, epoxy, or vinyl ester resin without melting. To avoid waste, please follow the recommended temperature range and pour in small batches.
