Why Use Boat Foam?

EPE or XPE sheets compared to liquid pour foams (PU expanding foams):

 Sufficient Drainage – Liquid pour boat foam or polyurethane (PU) expanding foam can fill the void a little too well, preventing pathways for any drainage. Builders have reported stagnant water and water no longer getting to the transom or bilge pump. Rain water can also effect your boat build if sufficient drainage is not considered.

Closed Cell – Water cannot be absorbed by closed-cell foams that have the appropriate ATSM or JIS testing standards. See the water absorption testing and rating system >>

Longer lasting – Liquid pour boat foams are known to deteriorate.
With Neolon XPE lasting more than double the lifespan of EPE or poured foam in real-world installations and in accelerated aging tests >>

Easy to replace – simply remove the foam slabs and any other foam shapes from the void and refill. NO chemically bonded, weathered and hardened expanding foam to remove!

Less work to install – no mixing, no waiting to rise, no hazardous waste. Simply install with the reassurance that if you make a mistake you are able to simply replace.

No chemicals – Exposure to liquid expanding foam and hardeners is a safety risk.

“I didn’t use a liquid pour foam in my boat build… my theory was that sheet insulation foam has gaps that allow for drying out... I was right”

Sheet or Block Boat Foam

Buoyancy or Marine boat foams are often referred to as White or Grey in Australia. The white foams offered are an EPE foam (Expanded Polyethylene), a standard closed-cell packaging foam and budget marine buoyancy foam.

EPE foam is used and approved for many marine and buoyancy applications, most commonly installed in the hull or other voids. EPE or Neolon XPE are often used as a higher quality, mess-free alternative to pour foams, expanding foams etc. As it can simply be trimmed to size.

Users have also commented “it helps with the sturdiness of the deck and vessel overall once in the water”, in addition to this a cut to shape foam will support the deck more evenly as it always provides a flat surface with no low or high points.

Sheet or block foams like EPE or Neolon XPE also prevent pooling water and are much better at allowing any water to find its way to the transom or bilge pump.

Neolon XPE (grey colour) Boat Foam - The Difference:

Over 10 years lifespan – An investment in Neolon XPE could save you a lot of time, money and effort when it comes to rebuilding the vessel in the future.

Increase buoyancy – To estimate the floatation force of foam see our Floatation Calculator

Fuel Resistant – In the chance that the Neolon XPE boat foam material is exposed to fuel it will not degrade. Other foams are very weak when exposed to chemicals and can reduce to almost nothing!

Flame and ignition retardant – Neolon XPE will not become flammable if there is a situation involving spark or flame.
