Ever find yourself cutting material just to make it "fit somehow"? You’re not alone — and let’s face it, the result often falls short. Stiff boards don’t flex or fill tricky gaps. Cork granules solve that problem: they adapt with ease. No trimming needed, no headaches. Lightweight, naturally sourced, and ready to use right out of the bag.

WHAT EXACTLY ARE CORK GRANULES?
Simply put, they’re small pieces of crushed natural cork. Super adaptable and long-lasting, they won’t create dust like other materials. Cork granules easily pour and fill spaces that rigid boards just can’t handle.
WHERE CAN YOU USE CORK GRANULES?
The possibilities are endless:
- Construction and industrial use: great for lightweight concrete, plasters, adhesives, and foundations.
- Insulation: excellent for filling wall cavities and hard-to-reach spots.
- Composites: perfect as a lightweight core in cabins and specialty vehicles.
- Furniture making: eco-friendly stuffing for poufs and chairs.
- Footwear production: useful for comfortable soles and insoles.
- Sports and play areas: ideal filler for punching bags, sports balls, and safe playground surfaces.
- Gardening: improves soil structure and airflow.
- DIY and modeling: perfect for miniature landscapes, nativity scenes, and stage props.
- Terrariums: makes a natural and safe substrate.
- Spill cleanup: absorbs oil and other liquid spills fast.
ARE CORK GRANULES CERTIFIED SAFE?
Yes, absolutely! Certified by Poland’s National Institute of Public Health (PZH), our granules are skin-safe, hypoallergenic, and free of harmful side effects. We’re also proud to be Poland’s exclusive supplier of certified cork granules.
WHAT ABOUT THEIR WEIGHT?
Granule weight depends on size:
- 0.5 – 1.0 mm: 140–150 kg/m³.
- 1 – 2 mm: 100–110 kg/m³.
- 2 – 3 mm: 120–130 kg/m³.
- 3 – 4 mm: 110–120 kg/m³.
- 4 – 5 mm: 120–130 kg/m³.
IS NATURAL CORK ECO-FRIENDLY?
Definitely. Cork comes from the bark of living cork oaks — harvested without cutting down trees. This means it’s renewable, biodegradable, and leaves no waste behind. A true eco-choice!
HOW IS CORK GRANULE MADE?
The process is simple but careful: bark from cork oaks is harvested every 9–12 years, then dried, cleaned, and crushed into granules in various sizes — from powder-fine to chunkier bits.
DO GRANULES RETAIN THEIR PROPERTIES?
Absolutely. Even after being crushed, cork keeps its outstanding qualities — insulating against heat, moisture, and sound. Plus, in granular form, it’s easier to work with and incredibly flexible.
DOES CORK PROVIDE GOOD INSULATION?
It sure does! Cork naturally insulates both heat and noise thanks to tiny air pockets trapped inside. Unlike synthetic options, cork does all this without chemicals. It’s light, breathable, and safe — for you and the environment.
ARE THERE OTHER OPTIONS AVAILABLE?
Yes, we offer a few choices:
- Cork dust — very fine and powder-like.
- Cork nuggets — larger pieces when you need more volume but still want loose fill.
WHAT’S THE BEST WAY TO STORE THEM?
Store cork granules in a cool, dry spot like a basement, garage, or pantry. Avoid heat and direct sunlight. Seal tightly to keep them in top shape.
CAN YOU USE THEM FOR WALKWAYS?
Absolutely! Cork granules offer soft footing, cushion every step, and stay cool and clean — unlike gravel or concrete that can overheat or get muddy after rain.
Most materials either come bulky and tough to handle or too delicate to last. Cork granules offer a natural, lightweight, and incredibly adaptable solution. They shine where other materials fall short — navigating tight corners, irregular shapes, and any spot where precision and flexibility matter most.
#1 ONE MATERIAL. ENDLESS USES.
Standard insulation options like foam boards, mineral wool, or spray foam often demand compromises. They need to be trimmed, reshaped, and frequently force you to adjust your entire approach. That takes up valuable time and energy.
Cork granules change the game. They naturally fit into any available space, making them a go-to choice for builders and contractors. From lightweight concrete to thermal plasters, binding compounds to foundation fills — cork granules deliver reliable insulation while filling gaps seamlessly.
#2 LIGHT INSULATION WITH BIG IMPACT
Offering excellent thermal and acoustic protection, cork granules trap air in countless tiny pockets. This creates an effective barrier against heat fluctuations and noise. They're also featherlight, so they won’t weigh down your structure like other fillers might.
Whether blended into plaster or concrete, cork brings serious performance upgrades. Expect better heat retention, reduced noise, and an overall lighter, easier-to-handle solution.
#3 SAFETY CERTIFIED — AND THAT’S PROVEN
Many products claim to be safe — but few back it up. Our cork granules carry a recognized hygiene certificate from the Polish National Institute of Public Health (PZH). They're 100% safe for skin contact — non-irritating, allergy-friendly, and free of harsh reactions.
That’s why they’re trusted in places where safety is non-negotiable. Whether it’s a playground, a sports field, or any active space, cork granules cushion impacts naturally, lower the chance of scrapes, and help prevent injuries. Peace of mind comes standard.
#4 STRAIGHT FROM NATURE — NOTHING ADDED
Our cork granules are made from pure, natural cork — no synthetic fillers, no additives, no dyes. Harvested in Portugal, a country renowned for cork production and traditional methods, these granules celebrate both quality and sustainability.
This isn’t about marketing buzzwords — it’s truly eco-friendly. The bark is removed with care, allowing trees to continue thriving and regenerating. Cork grows naturally, requiring no intensive farming, and represents a balance of nature and tradition.
#5 BUILT TO LAST — YEAR AFTER YEAR
Beyond its insulating powers, cork granules are highly durable. They naturally resist mold and mildew and aren’t attractive to insects or rodents. Even pests like ants and termites pass them by.
Cork is also non-conductive, making it safe around electrical setups. Plus, thanks to its excellent chemical stability, it retains its performance and structure over the long haul — giving you reliable results for years to come.
