Granulated cork

Tired of wrestling with insulation that just won’t cooperate around odd corners and tricky gaps? Standard sheets and rolls don’t always cut it — literally. Instead of moving forward, you’re stuck trimming and tweaking, wasting hours and running up the bill, only to end up with a less-than-perfect result. Cork granules offer a smarter, faster solution. Pour them straight into wall cavities, construction mixes, or over plaster where coverage is needed. Backed by certification from Poland’s National Institute of Hygiene, they’re proven safe — giving you the confidence to build on your terms, without compromises.

SO, WHAT EXACTLY ARE CORK GRANULES?

In a nutshell, they’re ground-up natural cork. These medium-sized granules are made by milling the bark from cork oak trees. Thanks to their open structure, they’re super lightweight, naturally efficient, and retain all the standout qualities cork is known for—like being moisture-resistant and antimicrobial.

HOW CAN CORK GRANULES BE USED?

Cork granules are incredibly versatile. Here's how people put them to work:

Construction & industrial use: Ideal as an additive in lightweight concrete, thermal insulation plasters, bonding compounds, and foundation bases.
Insulation: Excellent for filling wall cavities and boosting energy efficiency.
Composite structures: Works as a flexible, low-weight core for cabins and parts in specialty vehicles.
Furniture design: An eco-friendly filler for poufs, chairs, and armchairs.
Footwear production: Great in soles and inserts—light, breathable, and cushioned.
Safe surface material: Acts as a shock-absorbing layer on sports fields, playgrounds, or as a sand alternative on man-made beaches.
Sports gear: Found in punching bags, shooting rests, shuttlecocks, and training balls.
Landscaping & gardening: Enhances soil texture and ventilation—acts as a natural soil booster.
Crafting & scenic design: Awesome for imitating sand, rocks, or gravel in miniature builds, theatrical sets, or creative décor projects.
Terrariums: Safe and natural bedding for reptiles, spiders, and other exotic pets.
Spill control: Absorbs oils and liquids—commonly used to clean up spills and environmental messes.

ARE CORK GRANULES SAFE TO USE?

You bet! Cork granules come with an official hygiene certification from the National Institute of Public Health in Poland. They’re hypoallergenic, skin-safe, and won’t cause irritation. As of now, we’re proud to be the only company in Poland supplying cork granules with this certification.

ARE CORK GRANULES AN ECO-FRIENDLY OPTION?

Absolutely. Made from natural cork, these granules are fully renewable and biodegradable. Harvesting the bark doesn’t damage the cork trees—it actually helps them thrive and regenerate naturally.

CAN THEY BE USED ON ATHLETIC FIELDS?

Definitely! We supply cork granules engineered for synthetic turf. They’re a clean, natural, and safer alternative to rubber infill materials.

Traditional rolled or panel insulation can be pretty rigid — you often have to work around it rather than it working for you. That’s where cork granules stand out: they adapt to your needs. Fill gaps, blend them into plaster or concrete—they’re perfect for renovations and new construction alike.

Of course, not every project calls for the same cork granule type. Need a chunkier size for lightweight structural concrete? You got it. Need something finer for finishing plaster or sound-dampening mixtures? We’ve got that covered too. Think of it like a toolbox—you don’t use one screwdriver for everything, right? Same deal here. That’s why we offer a full range of grain sizes to fit whatever you’re working on.

And here’s the best part—cork granules are totally safe. They contain zero harsh chemicals, are gentle on skin, and allergy-friendly. That’s a big deal in places where people interact with materials every day—like daycares, schools, apartments, or public play areas.

Plus, adding cork to your construction mixes actually improves performance. Formulas with cork granules deliver superior thermal and sound insulation, hold up longer over time, and keep things lightweight. The result? More comfort indoors and reduced energy bills over the long haul.
