Cork rolls as a base for underfloor heating is an increasingly popular choice due to its insulating and ecological properties. Here are the details on the use of cork roll in the context of underfloor heating:

Advantages of using a cork roll under underfloor heating:
Thermal isolation:

Cork has excellent insulating properties, which helps retain heat in the room and use energy efficiently.
Sound insulation:

The cork effectively muffles sounds, which can contribute to quieter operation of the underfloor heating system and reduce noise in the room.
Eco-friendliness:

Cork is a natural and renewable material, making it an eco-friendly choice in construction.
Moisture and mildew resistance:

Cork is naturally resistant to moisture and mold, which is important in the context of underfloor heating systems where condensation may occur.
Installation of a cork roll for underfloor heating:
Substrate preparation:

Make sure the substrate is even, clean and dry. If necessary, use appropriate leveling materials.
Installing the cork roll:

Unroll the cork roll and cut it into appropriate pieces to fit the floor surface.
Use appropriate glue to attach the cork to the substrate. The adhesive should be resistant to high temperatures generated by the underfloor heating system.
Heating system installation:

Once the plug is in place, install the underfloor heating system according to the manufacturer's instructions.
Applying the finishing layer:

After installing the heating system, apply an appropriate finishing layer such as tiles, floor panels or other finishing materials.
Important notes:
Make sure the cork roll is of the appropriate thickness, usually 2-6mm, to ensure adequate insulating properties and strength.
Check the compatibility of the cork roll with the underfloor heating system, especially in terms of operating temperature.
Summary:
Cork roll is an excellent insulating material for use under underfloor heating, offering both thermal and acoustic insulation as well as ecological benefits. Correctly installed, it can help to increase energy efficiency and comfort in a room.

A cork rolls as a material for cork boards in the office is a practical and aesthetic solution. Cork boards are used to pin notes, documents, photos and other information, making them an ideal organizational tool in the office. Here are the details on how to use a cork roll for this purpose:

Advantages of using a cork roll for cork boards:
Ease of installation:

Cork rolls are easy to cut to size, which allows you to adapt the board to the available space in the office.
Eco-friendliness:

Cork is a natural and renewable material, which makes cork boards environmentally friendly.
Durability:

Cork is a durable material that retains its properties for a long time, even with frequent use.
Aesthetics:

The natural appearance of cork adds warmth and elegance to the office space.
Functionality:

The cork is soft, which allows you to easily attach and remove pins without damaging the surface.
Steps to create a cork board from a cork roll:
Materials needed:

Cork roll
Backing board (e.g. MDF, plywood)
Cork glue or double-sided tape
Wallpaper cutter or scissors
Ruler and pencil
Frame (optional)
Preparation:

Measure and cut the cork roll and backing board to the desired dimensions.
Make sure the surface of the backing board is clean and dry.
Installation:

Apply the cork glue evenly onto the surface of the backing board.
Carefully place the cork roll against the board, starting at one end and slowly moving to the other to avoid air bubbles.
Press the cork against the board to make sure the glue has set properly.
Finish:

If you are using a frame, attach it around the edge of the cork board.
Allow the board to dry completely according to the adhesive manufacturer's recommendations.
Wall mounting:

Use screws, hooks or mounting tape to attach your cork board to your office wall.
Additional tips:
Cork Thickness: Make sure the cork roll you use is thick enough (usually 3-6mm) to hold the pins well.
Personalization: The cork board can be painted or decorated to match your office decor.
Maintenance: Clean the cork board regularly with a dry cloth to remove dust and dirt.
Summary:
Cork roll is an excellent material for cork boards in the office, offering durability, aesthetics and functionality. Thanks to easy assembly and the possibility of adapting to your needs, cork boards made of a cork roll are a practical organizational tool that can improve work efficiency and the aesthetics of the office space.

Research on the permeability of liquids and gases through a cork roll focuses on its cellular structure and physical properties. Cork, as a material with a unique structure, has interesting features in terms of permeability that are important in various industrial and scientific applications. Here are the details about the permeability of liquids and gases through the cork roll and the relevant tests and experiments:

Cellular structure of cork
Cork consists of microscopic, air-filled cells that are closed and impermeable. These cells create a barrier that minimizes the permeability of both liquids and gases.

Liquid permeability
Water absorption research:

Cork has very low water absorption due to its hydrophobic nature. Studies have shown that cork can absorb less than 3% of its weight in water, which is a result of its compact cellular structure.
Resistance to chemical liquids:

Cork is resistant to many chemicals, making it an ideal sealing material in the chemical and pharmaceutical industries. Tests have shown that the cork is impermeable to most organic and inorganic liquids.
Gas permeability
Gas permeability through the plug:

Due to its closed cellular structure, cork has very low gas permeability. Research on the permeability of gases (e.g. oxygen, carbon dioxide) through cork has shown that it is an extremely effective barrier.
Applications in the wine industry:

Cork is commonly used to close wine bottles because it effectively prevents gases from entering, thus protecting the quality of the wine. Laboratory tests on the gas permeability of wine corks show minimal gas migration, which is crucial for long-term wine storage.
Laboratory experiments and tests
Liquid sorption tests:

In laboratories, liquid sorption tests are performed on cork samples, measuring the amount of liquid absorbed in a given time. Various liquids are used to test the resistance of the cork to different substances.
Gas permeability tests:

Specialized permeability chambers are used in which cork samples are exposed to various gases at controlled pressure. The amount of gas passing through the cap per unit of time is measured, which allows for the assessment of its barrier properties.
Research conclusions
Effectiveness as a barrier: Cork is a highly effective barrier to liquids and gases thanks to its closed, cellular structure.
Practical applications: The research results emphasize the usefulness of cork in the food, chemical and pharmaceutical industries, where high tightness and resistance to chemicals are required.
Innovative uses: Cork is being explored for new uses, such as insulation in green buildings, sealing materials in space technologies, and as decorative and functional elements in interior design.
Summary
Thanks to its cellular structure, cork roll is characterized by very low permeability to both liquids and gases. Laboratory tests confirm its effectiveness as an insulating and sealing material. These properties make cork a valued material in many industries and in modern and ecological applications.
