Extruded polystyrene XPS is a rigid thermal insulation solution, recommended for foundations, plinths, floors, terraces, roofs and areas exposed to moisture or mechanical stress. Due to its closed-cell structure, XPS offers a combination of thermal performance, compressive strength and low water absorption, making it suitable for a wide range of construction applications.
Extruded polystyrene (XPS) is a rigid thermal insulation material, made by extruding polystyrene and characterized by a closed cell structure. Due to its structure, XPS offers very good thermal insulation, low water absorption and high compressive strength, making it suitable for both new construction and renovation works.
XPS boards are easy to handle and process and can be used in numerous applications where high-performance thermal insulation and resistance to moisture and mechanical stress are required.
What is XPS extruded polystyrene used for?
XPS is mainly used for:
Insulation of foundations and plinths – protects areas in contact with the ground and helps reduce heat loss.
Insulation of floors – can be used under screeds, including in areas subject to significant mechanical loads.
Insulation of terraces – suitable for thermal insulation systems where the material must resist moisture and compression.
Insulation of roofs – used in certain roof systems, including terrace roofs.
Insulation of basement walls – provides thermal protection in areas exposed to moisture.
Insulation of walls and areas with thermal bridges, depending on the construction system.
Insulation of industrial floors and areas with traffic, when the requirements of the construction system are met.
Insulation of elements in contact with the ground, due to low water absorption.
Advantages of extruded polystyrene
✓ Efficient thermal insulation
Contributes to reducing heat transfer and improving the energy efficiency of the building.
✓ High compressive strength
It is suitable for applications where the thermal insulation is subjected to mechanical loads.
✓ Low water absorption
The closed cell structure limits water penetration, which makes XPS suitable for use in areas with high humidity.
✓ Durability
It can maintain its thermal and mechanical properties for long periods, when used correctly within the construction system.
