Schools
The use of Granab in schools brings alot of benefits in projects with a light structure like CLT or hollowcore or renovation projects linked to moisture or mould damage. Our systems for this type of project are made of galvanised steel and are consistently made of non-organic material, which is necessary for this type of project. With easy height adjustment of the subfloor system, it adapts to your project while continuously ventilating the air between the concrete or CLT and the floorboards.

Sustainable and functional solutions for educational environments
Schools and preschools need flooring that can withstand daily use by children and students. Choosing flooring for a school is therefore an investment that will affect the working environment and well-being of both students and school staff for many years to come. The right materials and systems provide sustainable solutions that are safe, hygienic and easy to maintain.
Why the choice of flooring matters
A good educational environment is fundamental to pupils’ development and learning. Flooring creates safe spaces where children can move around freely. Sustainable flooring contributes to reduced emissions and a better indoor environment, which is important for health and quality in buildings where pupils spend long periods of time every day.
Modern flooring systems for schools are more than just functional surfaces. They provide a good acoustic environment through effective sound insulation, which is essential in large premises where noise would otherwise disturb concentration. At the same time, the flooring should be comfortable to avoid aches and pains for both pupils and staff.
38mm chipboard with carpet is commonly used in schools.
Schools belong to room category B according to EN Eurocodes load category requirements.
This means that a 38mm chipboard or 2x22mm chipboards are required to meet the load category requirement.
Granab is always delivered with pre-assembled dampening elements and blocks. In addition, extra blocks and dampening elements are supplied for any adaptations on site.
Flooring types for different environments
Different types of flooring are used in schools and preschools, each with specific advantages. Linoleum is popular due to its durability and natural properties. Linoleum flooring is easy to clean and can be used in wet rooms where hygiene is particularly important.
Textile flooring effectively dampens sound, while homogeneous plastic flooring offers resistance to wear and tear. Wooden flooring provides a warm feeling that is appreciated in preschools. The choice of material needs to be adapted to the specific needs of each room.
The Granab system can be combined with different floor coverings such as parquet, linoleum, tiles or wood, which provides great flexibility in the choice of materials.
Sustainable flooring for the future
Sustainable flooring is an investment that will benefit future generations. Granab’s floor screed system is an example of a product that combines low emissions with a long service life. The system weighs only 5 kg/m² compared to old screeds weighing 100-200 kg/m², which means less environmental impact during installation.
With 25 years of experience, Granab has developed systems that are environmentally certified with different material choices. Systems 3000N, 7000N and 9000N consist of non-organic materials that provide good resistance to moisture and temperature changes. This helps the floors last longer, and longevity goes hand in hand with quality when the right system is chosen from the outset. If the joists are made of wood, System 8000W can be used to build even more environmentally friendly.

Sound insulation and comfort in schools
A good sound environment is now a priority requirement when building or renovating schools and preschools. The Granab system comfortably meets the sound requirements of Swedish standard SS 25268 for premises. Effective impact sound insulation and airborne sound insulation create a quieter environment where pupils can concentrate better.
The system offers comfortable and convenient flooring with built-in shock absorption. This is crucial, as hard floors can cause pain in the shoulders, back and legs of staff. Documented deflection under point loading demonstrates optimal comfort.
Flexible cable routing between joists and floor surfaces is an advantage where electrical, data and telecommunications needs change over time. Installations that are routed freely under the system do not cause disturbing structure-borne noise, which contributes to more harmonious spaces for everyone in the building.
Summary
Choosing the right flooring for schools and preschools is an investment that will affect the working environment and studies for many years to come. Sustainable products that combine functionality with good sound insulation, comfort and low environmental impact provide the right conditions for learning. Granab offers systems that meet high quality standards while being easy to install and maintain. Contact us for more information on how we can help you create a better school environment.
Ventilated subfloor
Granab in combination with mechanical ventilation allows you to effectively ventilate away any moisture and emissions from the floor.
Granab also offers a wall-mounted ventilation grille. It is a common solution for ventilated subfloors in schools.
The air is spread over the slab surface by means of perforated ducts placed on the slab.
The fans offered by Granab are approved by Byggvarubedömningen.
The air in the floor construction flows over the slab surface to a perforated duct connected to an exhaust fan.
