Marine Floating Floor Manufacturers & Systems
Marine floating floor systems — the A-60 fire-rated build-ups installed on ships’ steel decks — are made by a handful of established European manufacturers: GTF Freese, Sika, Saint-Gobain Weber, Rockwool and Marlon Marine among them, while familiar names such as Prolance are installation contractors that fit these systems rather than make them. The products differ less by brand than by system family: mineral-wool-plus-screed, lightweight insulating screed, prefabricated panel or visco-elastic damped construction.
This guide maps who makes what on the European market, how the system families differ technically, and how to compare quotes on certified facts — from an independent supplier that ships one of these systems across the EU. Brand information is drawn from the manufacturers’ public technical documentation; all trademarks belong to their owners.
Four System Families
Every certified A-60 floating floor on the market is a variation of four basic constructions. Identify the family first — then compare manufacturers within it. Certified weights and thicknesses per family are in the weight & build-up guide.
Mineral wool + floating screed
The classic construction: marine stone wool slabs as the insulating core, a reinforced mineral screed floating on top. Robust and widely certified — and the heaviest of the four families.
Lightweight insulating screed
A pumpable low-density screed provides the fire insulation itself, topped by a thin load-distribution layer. Substantially less mass — the family that dominates refits and weight-critical newbuilds.
Prefabricated panel systems
Factory-made floor panels laid on insulation or bedding — fast, dry installation with predictable build height, at the cost of less flexibility around penetrations and complex deck geometry.
Visco-elastic damped build-ups
Any of the above with a visco-elastic damping layer inside the certified sequence — specified where comfort-class noise targets apply. How it works: the acoustics guide.
Who Makes What — European Manufacturers
A factual map of the established names, based on each manufacturer's public technical documentation. Portfolios evolve — the type-approval certificate of the specific offered system is always the document that decides.
GTF Freese — TEFROLITH / TEFROTEX
- Who: marine deck systems specialist, Bremen, Germany
- Makes: A-60 floating floor systems, lightweight insulating screeds, pumpable mineral screeds and visco-elastic damping layers
- Family: lightweight insulating screed + visco-elastic — the range Trivaro supplies EU-wide
Sika — Sikafloor Marine
- Who: Swiss construction-chemicals group
- Makes: the Sikafloor Marine range — levelling compounds, primary deck coverings, visco-elastic damping and floating floor constructions
- Family: screed-based and visco-elastic damped systems
Saint-Gobain Weber — weber marine
- Who: marine line of the French Saint-Gobain group
- Makes: self-levelling marine deck screeds and lightweight A-60 floating floor constructions
- Family: lightweight and classic screed-based systems
Rockwool — SeaRox
- Who: Danish stone wool group, marine & offshore division
- Makes: SeaRox marine stone wool — slabs and insulation used as the non-combustible core in floating floor build-ups
- Family: component supplier to mineral-wool-based systems, not complete walking floors
Marlon Marine — Marine Mortar
- Who: Danish marine flooring manufacturer
- Makes: lightweight marine screed compounds (Marine Mortar series), self-levelling compounds and A-60 floating floor / sound-damping systems
- Family: lightweight insulating screed systems
The installers — Prolance and others
- Who: turnkey installation contractors such as Prolance Marine Flooring — often found in the same searches, but not manufacturers
- Do: design plans, installation and maintenance of floor and deck systems on newbuilds and refits, using the manufacturers’ certified systems
- Family: the trade that puts any of the above on the deck — installation per the approval drawing is what keeps the rating valid
Qualifying an Alternative System
Specifications are often written around one manufacturer's system. Substituting an equivalent certified build-up is routine — when it is done as a system, not as a product swap.
Extract the requirements
What the specification actually demands: the fire rating (A-60/A-30/A-0), weight and height budget, acoustic target, deck areas and finish. The brand name in the spec is a reference solution — these numbers are the requirement.
Match a certified equivalent
Find a complete type-approved system that meets the same numbers — same rating, equal or better weight and acoustics — and present its certificate set alongside the specified one for the yard and Class to accept.
Confirm with Class & yard
The substitution is approved on paper before anything ships: certificate references into the fire control plan, datasheet figures into the weight calculation, and the installation drawings per the new approval.

Manufacturers & Alternatives — Frequently Asked Questions
What buyers and specifiers ask when comparing A-60 floating floor systems across brands.
01 Who manufactures A-60 marine floating floor systems in Europe?
The established European manufacturers include GTF Freese (TEFROLITH and TEFROTEX systems — supplied by Trivaro), Sika (Sikafloor Marine), Saint-Gobain Weber (weber marine screeds), Rockwool (SeaRox stone wool, the insulating core in many slab-based build-ups) and Marlon Marine (Marine Mortar screeds). Names like Prolance Marine Flooring that appear in the same searches are installation contractors, not makers. The portfolios map to four underlying system families — and every certified system is type-approved as a complete, named layer sequence.
02 Can components from different manufacturers be mixed in one A-60 floor?
Only if that exact combination was fire-tested and type-approved. The A-60 rating belongs to the complete tested build-up — the certificate names each layer, material and thickness. Some certificates do list approved third-party components (a named stone wool, a named deck covering); the certificate text decides, not the datasheets.
03 Is there an alternative to Sikafloor Marine or other brand systems?
Yes — the market has several independently certified system families, so a specification written around one brand can usually be met by an equivalent type-approved build-up from another manufacturer, subject to yard and Class accepting the substitution as a complete system. Typical triggers: lead time, installed weight, build height, installation method or single-source risk. Trivaro supplies the certified GTF Freese systems as one such route.
04 Is Rockwool SeaRox a complete A-60 floating floor?
No — SeaRox is the marine stone wool range: in floating floors it is the non-combustible insulating core. A complete A-60 floor adds the floating load-distribution layer, the IMO-approved primary deck covering and the visible finish, all fire-tested together as one system. Several manufacturers’ certified systems are built around stone wool slabs of this kind.
05 What should I request to compare quotes fairly?
The same six items from every bidder: type-approval certificate of the offered build-up, certified kg/m² and build height, acoustic test report where targets apply, installation method with curing times, MED wheelmark status, and lead time with the documentation package. Comparing brochures instead of certificates is the most common sourcing mistake.
06 Which systems does Trivaro supply?
Trivaro is an independent B2B supplier delivering the certified GTF Freese marine deck systems EU-wide — TEFROLITH A-60 floating floors, insulating and mineral screeds, visco-elastic damping — plus IMO-approved visible finishes from the marine range. Every delivery includes the complete certificate package, and we quote certified datasheet figures per zone.
Comparing A-60 Systems for a Project?
Send us the specification you are working against — required divisions, deck areas, weight and acoustic targets, and the reference system if one is named. We respond with a certified GTF Freese build-up per zone, type-approval references and datasheet figures side by side with your requirements, and a B2B quotation with the full documentation package.
Independent advice included: if our system is not the right fit for a zone, we say so.
