12mm Thick Laminate Flooring
12mm is the thickest of the common laminate thicknesses. It is the one to choose when you want a floor that feels solid and substantial underfoot. The extra thickness comes from a deeper high-density fibreboard core, which gives the board more stability, a quieter, more reassuring step and a feel much closer to real wood than a thin laminate. It is a hard-wearing, premium choice that suits busy homes and any room where you want the floor to feel high quality.
You can have 12mm boards across our laminate ranges. Quick-Step is the one we recommend by default and the name most associated with laminate in the UK, offering 12mm boards in several ranges. The Lignum collection includes a 12mm herringbone in its Lignum Fusion range. Evergreen adds further choice on design and price. All of it is available to buy online with free UK delivery.

Why Choose 12mm Laminate?
The thickness of a laminate board changes how the floor feels and performs. A 12mm board is noticeably more solid underfoot than a thinner one: less give and a quieter, less hollow step, especially over a good underlay. The deeper core is also more stable and more forgiving of small imperfections in the subfloor, so the finished floor looks and feels flatter and more professional. For many people the biggest draw is simply that a 12mm laminate feels closer to a real wood floor, which is exactly what you want in a living room, hallway or anywhere the floor is on show.
12mm vs Thinner Laminate
Laminate is usually sold in thicknesses from around 7mm up to 12mm. The table shows how they compare, so you can decide how much thickness is worth to you.
| Feature | 12mm | 8mm | 7mm |
|---|---|---|---|
| Feel underfoot | Most solid; closest to real wood | Solid | Lighter; more give |
| Sound | Quietest over underlay | Quiet over underlay | Can sound more hollow |
| Subfloor tolerance | Most forgiving of minor unevenness | Good | Needs a flatter subfloor |
| Typical cost | Highest within laminate | Mid | Most affordable |
| Best for | Living areas and where feel matters | Everyday rooms | Budget and lighter-use rooms |
If the feel of the floor matters to you, 12mm is worth the small step up. If you are working to a tight budget or flooring a lighter-use room, an 8mm or 7mm board still gives you a good-looking, hard-wearing floor. We also stock 9mm and 9.5mm boards in between.
Is Thicker Laminate More Durable?
It is a common assumption that a thicker laminate is automatically more hard-wearing, but the two are not the same thing. Thickness affects how solid and stable the floor feels. Durability, or how well the surface resists scratches and wear, is set by the AC rating, not the thickness. The ideal for a busy home is a 12mm board with an AC4 rating: you get the solid, quiet feel of the thicker core and a hard-wearing surface built for years of everyday use.
12mm in Every Look
A 12mm board comes in all the popular laminate looks. It is especially popular in herringbone, where the extra thickness gives the parquet pattern a solid, quality feel. Grey and natural oak tones suit a modern or classic finish. You can also have 12mm in wide plank boards and stone and tile effects. Whatever the look, a 12mm board gives it a more substantial feel underfoot.
Comfort, Sound and Subfloor
Two of the biggest benefits of a 12mm board show up in comfort and sound. The thicker core gives a more solid, cushioned step and, over a quality acoustic underlay, cuts the hollow click that thinner laminate can make. The extra rigidity also bridges minor dips and bumps in the subfloor better than a thin board, though a clean, dry and reasonably level subfloor is still important for any laminate. Pair a 12mm board with a good underlay and you have about the most comfortable, solid laminate floor you can lay.
Laminate and Underfloor Heating
Most of our 12mm laminate works with both electric and wet underfloor heating, subject to a maximum surface temperature of around 27C and the manufacturer’s guidance. A thicker board carries heat a little more slowly than a thin one, but it still performs well over underfloor heating in everyday use. Let the boards acclimatise in the room first and follow the installation instructions supplied with your chosen range.

Frequently Asked Questions
Is 12mm laminate better than 8mm?
It depends on what you want. A 12mm board feels more solid and substantial underfoot, is quieter over underlay and copes better with a slightly uneven subfloor than an 8mm board. An 8mm board is more affordable and perfectly good for everyday rooms. If the feel of the floor matters to you, 12mm is worth the small step up.
Is thicker laminate more durable?
Not on its own. Thickness affects how solid and stable a floor feels, but durability, meaning resistance to scratches and wear, is set by the AC rating rather than the thickness. A thick board with a low AC rating can still scratch, while a thinner board with a high AC rating can be very hard-wearing. For a busy home, look for a 12mm board with an AC4 rating to get both.
Is 12mm laminate good for a busy home?
Yes. A 12mm board with an AC4 rating is one of the best laminate choices for a busy family home. The thicker core gives a solid, quiet floor and the AC4 surface stands up to children, pets and heavy foot traffic. It is a hard-wearing, high-quality option for living rooms, hallways and open-plan spaces.
Is 12mm laminate quieter to walk on?
It is quieter than a thinner board, yes. The extra thickness reduces the hollow, clicky sound laminate can sometimes make. To get the best from it, lay a 12mm board over a good acoustic underlay, which softens footfall further and, in an upstairs room, cuts the noise carried to the room below.
Can I get 12mm herringbone or waterproof laminate?
Yes to both. We stock a 12mm herringbone within the Lignum Fusion range, so you can have the parquet look in a thick, solid board. For a waterproof 12mm floor, choose a Quick-Step waterproof range, as Quick-Step is the range we stock with waterproof options.
