Houseboat looking rough?

We can help with new panels!

Save Weight without Sacrificing Comfort

When you’re building or repairing a boat, you have to constantly consider the compromise between functionality, comfort, and weight. Traditional materials are frequently too heavy to consider.

Composite panels are a great alternative material to make that compromise simpler. With a single product, you’re able to increase the structural integrity, insulation, and comfort of your build–all from a lightweight frame.

Panels Unlimited custom-builds marine-use panels to your exact specifications. Depending upon material composition, we’re able to build up to 4’ x 24’ panels.

If you’re enclosing a pontoon or building a houseboat, contact Panels Unlimited today to learn how our composite panels can simplify that process.

What is a Composite Panel?

Panels Unlimited composite panels are a high energy-efficiency building material that includes expanded polystyrene (EPS) “sandwiched” by two facings. The facings provide rigidity and waterproofing, while the polystyrene adds structural integrity and insulation.

This means that our panels are:

  • Durable
  • Lightweight
  • Easy to use
  • Energy-efficient

Composite panels are tailor-made for marine applications. Whether you’re building a DIY houseboat, enclosing a pontoon, or modifying a luxury vessel, composite panels are an affordable, efficient, and capable material.

Can a 3/4" thick piece of foam support a 270lb. man?

Only if it's in a laminated panel!
