FAQ

Is thermal expansion an issue?

Minor; engineers account for it during layup.

Does PVC foam compress under vacuum?

Quality foams have very low compression under vacuum pressure.

Can foam be layered in multiple densities?

Yes. Multi-density configurations optimize weight and strength.

Does PVC foam require vacuum bagging?

Not always, but vacuum bagging improves bonding.

What density is used for transoms?

160–250 kg/m³ for compression strength.

What density is used for decks?

60–100 kg/m³, depending on span and load.

What density is used for hull bottoms?

Typically 80–130 kg/m³ for slamming areas.

Can PVC foam replace aluminum honeycomb in superstructures?

Often yes, due to easier processing and better impact

Is PVC foam suitable for high-speed boats?

Yes. It withstands slamming loads and high dynamic stresses.
