(excl. VAT)A floor may look perfectly fine on the surface, but that doesn’t always reveal what’s going on underneath. Moisture and mold can quietly develop below the flooring — and by the time it becomes noticeable, the damage is often beyond repair. Fortunately, you can avoid these costly surprises by choosing a Cork Underlayment with an Aluminum Layer. This underlayment forms a dependable moisture barrier and keeps your flooring protected from the bottom up. It’s a long-lasting, proven solution — unlike cheap foam underlays that simply don’t deliver in real-world conditions.

Anywhere you need a serious moisture barrier. The blend of cork and aluminum provides far better moisture protection than standard underlayments commonly used in homes.
It’s also a smart choice for areas where the subfloor tends to feel cold or where temperatures regularly run high. In those situations, the aluminum film acts like a thermal reflector — bouncing heat away from hot surfaces and reducing heat loss on cooler ones.
Together, cork and aluminum create a much more efficient and balanced protection system for your flooring. Aluminum blocks moisture and reflects heat, while cork adds warmth, sound absorption, and stability. The duo gives you performance you simply won’t get when using either material on its own.
In many homes, yes — cork does a great job with insulation, warmth, and sound reduction. But if the subfloor has a high moisture level and the cork is fully enclosed by flooring, mold may develop where moisture meets the cork. This is a natural reaction and can happen with any material. In those cases, it’s far safer to choose an underlayment with an aluminum layer to properly block moisture.
Absolutely — cork has naturally insulating and sound-absorbing qualities that help reduce noise and make floors feel more comfortable underfoot.
Lay the underlayment with the aluminum side facing down, toward the subfloor. This placement stops moisture right at its source, keeping it away from both the cork and the flooring above it.

Moisture hiding beneath your flooring is one of those problems you rarely notice until real damage has already taken place. Fortunately, preventing it is easier than you’d think: switch from a basic underlayment to a cork option reinforced with an aluminum layer. This upgrade creates a highly effective moisture shield and performs especially well in areas where the subfloor tends to run unusually cold or warm.

Moisture creeping up from below often goes unnoticed — until it suddenly becomes a costly issue. Skipping a quality underlayment during installation or using low-grade foam gives moisture a direct path to rise into the flooring.
A cork underlayment paired with an aluminum layer acts as a reliable moisture barrier: the cork adds stability, while the aluminum prevents dampness from penetrating upward. Together, they deliver long-lasting protection for your floors.
Temperature swings in the subfloor — whether too cold or too warm — are more common than most homeowners realize, and they make everyday use noticeably less comfortable. The aluminum layer built into the cork underlayment works as a high-performance thermal buffer that evens out these extremes.
When the base is cold, the foil helps reduce heat transfer, keeping the floor warmer underfoot. When the subfloor heats up too quickly, the aluminum reflects the excess warmth, stopping it from entering the flooring surface. The end result is a consistently comfortable floor — not icy, not overly hot, just pleasantly neutral day after day.
Cork and aluminum complement each other exceptionally well. Cork delivers quietness, cushioning, and stability, while aluminum boosts insulation and — most importantly — greatly strengthens moisture resistance.
This means you no longer need to choose between comfort and durability. With this underlayment, you get both: improved thermal performance and moisture protection lead to fewer issues over time, fewer repairs, and a floor that lasts much longer.
Cork is a natural and renewable resource harvested from the bark of cork oak trees, which regenerate after each harvest. The trees aren’t cut down — they continue growing in a healthy and sustainable cycle.
Of course, not every interior material can be fully eco-friendly — but where a better option exists, it’s worth choosing. An underlayment is essential for any flooring installation, so why not pick one with environmental benefits as well? Best of all, there’s no compromise on performance. Cork isn’t a temporary “green substitute” — it’s a durable, trustworthy material that stands the test of time.
