Cork is a solid choice for flooring. Soft underfoot, naturally insulating, sustainably harvested, and warm in a finished space. But once you've settled on cork, the next question follows quickly: which type of cork tile is right for your project? Portugal Cork Co offers a few genuinely different options, and knowing how they compare makes the decision much simpler.
The main choice comes down to raw cork tiles versus pre-finished veneer cork tiles, with the engineered Greenflow Collection sitting alongside them as a more heavy-duty option. All of them use real Portuguese cork. All of them are glued down for a stable, long-lasting floor. Where they differ is in how they arrive, how they're finished, and the kind of project each one suits. This guide walks through all three so you can choose with confidence.
Understanding Portugal Cork Co's Cork Flooring Range
Before comparing, it helps to be clear on what's actually on offer, because "cork tile" covers a few different products.
Portugal Cork Co's floor range breaks down into three main types. Raw cork floor tiles arrive unfinished and are sealed on site after installation. Pre-finished veneer cork floor tiles come with a factory-applied finish, so they're ready to install and walk on. The Greenflow Collection is a step up in engineering: a highly compressed cork core with a genuine cork veneer surface, built for durability in demanding settings.
Each has a place. The right one depends on the look you're after, the finish you want, and how hard the floor will be worked. The sections below cover each in turn, then bring them together in a side-by-side comparison.
Raw Cork Floor Tiles: Natural and Sealed on Site
Raw cork tiles are exactly what they sound like: genuine cork tiles supplied without a surface finish. Once they're laid and glued to the subfloor, they're sealed on site with a compatible coating, which is what makes the floor water-resistant and hard-wearing.
The appeal of raw cork is control. Because the finish goes on after installation, you have a say in the final surface, from the sheen level to the number of protective coats. For projects where a specific look matters, or where a specialist installer wants to tailor the finish, raw tiles give the most flexibility. You'll find suitable finishing products in the Adhesives & Coatings collection.
The trade-off is that raw tiles need that finishing step. It's an extra stage in the process and one worth handing to a professional, since the quality of the seal determines how well the floor holds up. Portugal Cork Co recommends most cork products be installed by a licensed tradesperson to make sure they go down safely and correctly.
Raw cork tiles suit you if:
-
You want control over the final finish and sheen
-
Your installer prefers to seal on site
-
You're matching an existing floor or a specific design brief
-
You're comfortable with the extra finishing stage
Pre-Finished Veneer Cork Floor Tiles: Factory-Finished and Ready to Install
Pre-finished veneer cork tiles solve the finishing question before the tiles even arrive. Each tile has a genuine cork veneer surface with a factory-applied protective finish, so once they're glued down, the floor is ready to use. The Champagne veneer tile is a good example, made from recycled wine and champagne stoppers and supplied in a 600 x 300 x 5mm format, ready for immediate installation.
For most residential projects, this is the straightforward option. There's no on-site sealing stage, the finish is consistent from tile to tile, and the result is predictable because the coating is applied in controlled factory conditions. You see exactly what you're getting when you order a sample.
Pre-finished tiles come in a range of tones and textures, from lighter, neutral finishes through to richer, darker looks, so there's scope to match most interiors without needing to finish anything yourself.
Pre-finished veneer tiles suit you if:
-
You want a ready-to-use floor with no on-site finishing
-
Consistency of finish across the floor matters
-
You're working to a residential timeline and want fewer stages
-
You prefer to choose from a set, proven finish
The Greenflow Collection: Engineered for Durability and Commercial Use
The Greenflow Collection is Portugal Cork Co's most engineered flooring option. Each board pairs a highly compressed cork core with a genuine cork veneer surface, and comes pre-finished with a high-resistance coating. Boards measure 1,225 x 195 x 7mm and carry GreenGuard Gold certification for low chemical emissions.
Greenflow is built to take more punishment than a standard tile, which is why it's the range Portugal Cork Co recommends for commercial and high-traffic settings, as well as demanding residential projects. The compressed core gives it durability, while the cork veneer keeps the comfort, warmth and acoustic softness cork is known for. It's a range designed with architects, designers and specifiers in mind, and it has been used in commercial fitouts where the floor has to look good and last.
Although Greenflow boards include a click system, Portugal Cork Co installs them glued down for the most stable, durable result, in line with the rest of the range.
Greenflow suits you if:
-
The floor will see commercial or high foot traffic
-
You want the most durable option in the range
-
Low-emission certification (GreenGuard Gold) matters for the project
-
You want an engineered board with the comfort of a real cork surface

All three are glued to the subfloor, and all three deliver the warmth, comfort and acoustic softness that make cork worth choosing. The differences are about finish and durability, not the material itself. For a broader look at how cork performs day to day, our guide to cork flooring pros and cons is a useful companion read.
How to Choose the Right Cork Floor for Your Project
A few practical questions make the choice clearer.
How hard will the floor be worked? For a busy commercial space or a high-traffic area at home, Greenflow is the range built for it. For a standard living room, bedroom or home office, a pre-finished veneer tile is usually all you need.
Do you want a say in the finish? If you or your installer want to control the final look, sheen and number of coats, raw cork tiles give you that flexibility. If you'd rather order a floor that's ready to use, pre-finished tiles or Greenflow take the finishing decision off your plate.
What's your timeline? Raw tiles add an on-site sealing stage, which takes time and is best done by a professional. Pre-finished tiles and Greenflow skip that step, so the floor is usable sooner after laying.
Who's installing it? Portugal Cork Co recommends a licensed tradesperson for most cork products, and all three options are glued down for a stable result. Raw tiles in particular benefit from an experienced installer, since the on-site seal affects how the floor wears.
If you're weighing it up, the simplest next step is to order a sample. Seeing the surface and finish in person makes the decision far easier than choosing from a screen.
Frequently Asked Questions
What's the difference between raw and pre-finished cork tiles?
Raw cork tiles arrive unfinished and are sealed on site after they're glued down, which lets you control the final finish. Pre-finished veneer cork tiles come with a factory-applied finish, so they're ready to use once installed. Raw tiles offer more flexibility; pre-finished tiles offer consistency and fewer stages. Both use genuine Portuguese cork, and both are glued to the subfloor.
Is the Greenflow Collection different from cork floor tiles?
Yes. Greenflow boards use a highly compressed cork core with a genuine cork veneer surface, which makes them more durable than a standard cork tile. They come pre-finished with a high-resistance coating and carry GreenGuard Gold certification. Portugal Cork Co recommends Greenflow for commercial and high-traffic projects, while standard cork tiles suit most residential spaces.
Do cork floor tiles need sealing?
Raw cork tiles do. They're sealed on site after installation, which makes the surface water-resistant and hard-wearing. Pre-finished veneer tiles and Greenflow boards arrive with a factory finish already applied, so no additional sealing is needed. Whichever you choose, wiping up spills promptly and following a simple care routine keeps the floor performing well.
How are Portugal Cork Co's cork floors installed?
All of Portugal Cork Co's cork floor tiles and Greenflow boards are glued down to the subfloor for a stable, durable result. The company recommends most cork products be installed by a licensed tradesperson to ensure they go down safely and correctly. A clean, level, dry subfloor is essential before installation begins.
Which cork floor is best for a commercial space?
The Greenflow Collection is the range built for commercial and high-traffic use. Its highly compressed cork core gives it added durability, the high-resistance finish stands up to wear, and its GreenGuard Gold certification suits projects with indoor air quality requirements, all while keeping the comfort and acoustic softness of a real cork surface.
Ready to Choose Your Cork Floor?
Whether you lean toward raw cork tiles for a tailored finish, pre-finished veneer tiles for a ready-to-use residential floor, or the Greenflow Collection for a commercial-grade result, the decision comes down to finish, durability and how the space will be used. All three are genuine Portuguese cork, all are glued down for stability, and all deliver the warmth and comfort cork is known for.
The clearest way to decide is to get the products in front of you. Order a sample of the tiles or finishes you're considering, and you'll see the quality and texture for yourself.
