Introduction to cork vaults.<\/h2>\n

The term cork tiles has become a common expression in the construction industry. However, what many call \u2018cork\u2019 is actually expanded polystyrene (EPS), a modern, efficient and widely used material. In this post, we explain the differences, advantages and uses of this type of ceiling tiles, especially in lightweight structures and thermal insulation.<\/p>\n

Are cork and EPS hollow bricks the same thing?<\/h2>\n

Yes, in practice, when people talk about cork tiles on the building site, they almost always refer to EPS tiles. Although technically they are not the same, the colloquial use of the term is due to the similar appearance and weight of both materials.
\nEPS (expanded polystyrene) is a foamed plastic material, composed of 97% air, white in colour and light in texture, easily recyclable like most plastics. This material is moulded in the form of hollow bricks that are integrated into floor slab systems, providing lightness and insulation.
\nNatural cork, on the other hand, comes from the bark of the cork oak tree. Although it has also been used historically in construction, it is less common due to its higher cost, carbon footprint and limited availability.<\/p>\n

Why is there so much talk about cork vaults in Mallorca?<\/strong><\/h2>\n

In everyday life on the construction site, it is common for workers, technicians and warehouses to use the term cork blocks to refer to the EPS product. This is due to:
\n– Its extremely light weight.
\n– Its appearance is similar to cork, although it is white in colour.
\n– Its ease of handling and installation.
\nThis widespread use has meant that, even in professional environments, both terms are used interchangeably, even if the product used is high quality EPS, such as the one we manufacture and distribute in Mallorca.<\/p>\n

Advantages of EPS floor slabs
\n<\/strong>Choosing cork (EPS) vaults over traditional ceramic or concrete vaults offers numerous advantages:
\n– Reduction of structural weight: ideal for lightening floor slabs in new construction and refurbishment.
\n– Easy handling and installation: saves time and effort on site.
\n– Excellent thermal and acoustic insulation: improves building comfort and energy efficiency.
\n– Recyclable and sustainable material: composed of more than 97% air, with low environmental impact.
\n– Compatible with different types of one-way slabs: adapts to modern construction solutions.<\/p>\n

Practical uses of cork blocks in the construction industry
\n<\/strong>Cork (EPS) hollow bricks<\/a> are mainly used in the following applications:
\n– One-way slabs: as a lightening element in reinforced concrete structures.
\n– Insulated roofs and sanitary slabs: contributing to the thermal insulation of the envelope.
\n– Residential, industrial and hotel construction: due to its thermal performance and ease of assembly.
\nIn addition, their resistance to the passage of time and humidity makes them an ideal solution for the climatic conditions of Mallorca.<\/p>\n

Conclusion<\/h2>\n

The so called cork<\/strong> vaults are actually expanded polystyrene (EPS) vaults<\/strong>, a modern, efficient and widely accepted material in construction due to its structural, thermal and sustainable advantages. At Polivas, we offer customised solutions with EPS vaults for all types of projects in Mallorca.
