Floor insulation solutions
Insulation under screed
Enhances the thermal and acoustic performance of floors.
Insulation under concrete slabs and floors
Lightweight and rigid, they provide excellent thermal insulation.
Inserts for prestressed beams
Reduces weight and increases spans without carriers.
Inserts for lattice girders
Robust, lightweight and optimizes the floor's thermal resistance.
Why insulate floors?
Insulating floors is essential for reducing heat loss and improving energy efficiency. Floors, especially in rooms above unheated basements, are a major source of heat loss. By insulating the floor, you reduce heating costs and improve thermal comfort. Acoustic insulation also reduces noise and vibrations. Insulating materials also guarantee the durability of structures, with excellent resistance to compression.
Advantages of polystyrene floor insulation
Expanded polystyrene (EPS) is a lightweight, versatile insulation material that improves the thermal and mechanical efficiency of buildings. Composed of 98% air, it offers low thermal conductivity and excellent load-bearing capacity. Easy to handle, durable and easy to install, EPS is also environmentally friendly, fully recyclable and helps reduce carbon footprints.
Easy installation of floor insulation solutions
Knauf Industries simplifies the installation of floor insulation. Start by making sure the floor is flat, and levelling if necessary. Install a resilient strip and lay the EPS insulation under the screed or slab. For floors with joists, position the joists and insert the EPS hourdis. Follow the steps to ensure optimum thermal and structural insulation.
