Expanded insulation cork sheets

Expanded insulation cork sheets are natural cork products and are perfect for thermal, acoustic and vibration insulation. Aglomerado Negro is a type of an agglomerated cork, which is frequently utilized as an insulating material. The product in question is an alternative to Styrofoam and mineral wool. Moreover its biggest advantage is the fact that it is fully natural, for the product is produced out of cork oak wood. The product is 100% natural, non-toxic, fungi-resistant, and durable. It does not lose its distinctive features, even after being utilized for many years. Expanded cork does not spread fire and is self-extinguishing.

Aglomerado Negro plates are a good thermal insulator  being also an excellent absorbent of damp. It is undoubtedly, the best material against damp.

Obviously that we are referring to a NATURAL and biodegradable insulator.

In conclusion expanded insulation cork sheets has been affirmed as the best natural insulation currently used in the construction sector.

Production of expanded cork:

Expanded cork, also known as cork agglomerate, is a material obtained from natural corks that are ground into small grains and then subjected to the expanding process. Here are the general steps in making expanded cork:

Harvesting Natural Corks: Similar to making traditional corks, the process begins with collecting the bark of the cork oak tree.

Grinding corks: The collected corks are then ground into fine pellets. At this stage you can obtain raw material, which undergoes further processes.

Expanding: Cork granules undergo an expansion process that uses high pressure and high temperature. This increases the volume of the cork and creates a structure with larger internal cavities.

Sorting and processing: The expanded cork is then sorted according to grain size and quality. Depending on the intended use, it can also go through further processing steps.

Finishing: Corca agglomerate can be subjected to various processes such as shaping, cutting or layering to adapt it to specific applications.

Application of expanded cork:

Sound insulation: Expanded cork is used as a sound insulation material in construction. Thanks to its structure with large internal cavities, it perfectly dampens noise.

Thermal insulation: Due to cork’s insulating properties, both thermal and acoustic, expanded cork can be used for thermal insulation in buildings.

Material for technical corks: Expanded cork can be used to produce various technical products such as seals, gaskets and shock-absorbing elements.

Material for craft and art projects: Expanded cork is lightweight, easy to work with and has an attractive texture, making it popular for craft and art projects.

Packaging: Expanded cork can be used in the production of packaging both as a protective insert and as a material for the packaging itself.

Furniture and interior design: Due to its lightness, flexibility and aesthetics, this material can be used in the manufacture of furniture or interior design elements.

Expanded cork is an alternative to natural cork in some applications, particularly when the insulating properties and lightness of the material are important.

Installing expanded cork on exterior walls is similar to Styrofoam.
As with Styrofoam, to protect it from the elements, it is necessary to cover the cork with mesh and plaster. Below is a tailored guide:

Surface preparation:

Make sure the wall surface is clean, dry and free of any contamination.
Repair any damage and smooth out any unevenness on the wall surface.
Material preparation:

Depending on the design, select cork boards of suitable dimensions.
Before assembly, store cork boards according to the manufacturer’s recommendations.

Cork bonding:

Apply cork glue to one side of the board and spread it evenly over the wall surface.
Place the cork board on the wall and press gently to avoid air getting between the cork and the wall.
Repeat this process for each sheet.
Mechanical assembly (optional):

If necessary, use an additional mechanical fastener such as: B. screws or dowels.
Network coverage:

After gluing the cork, apply the hidden mesh over the entire cork surface and secure it according to the manufacturer’s recommendations.
Applying plaster:

Once the mesh is in place, apply a layer of plaster to the surface of the cork and spread it gently.
Depending on your aesthetic preferences, you can choose between textured and smooth plaster.

After applying the plaster, adjust the surface to your liking, for example by painting or applying appropriate decorative coatings.
Follow the manufacturer’s recommendations for the specific type of expanded cork, mesh and plaster to ensure adequate protection from the elements and to maintain a durable and aesthetic finish.
