Xps Floor Insulation
XPS EXTRUDED INSULATION BOARD
Extruded board, also known as XPS board, is a rigid foam board made of polystyrene resin as raw material and extruded by heating. The material has an independent closed bubble structure inside, so it has excellent compressive strength and thermal insulation properties. At the same time, its surface is hard and flat, not easily deformed, and convenient for construction. Its main dimensions and technical information are as below table.

1. Physical performance parameters: The physical properties of extruded boards are stable. Its main parameters include: density is generally 25-35kg/m³, thermal conductivity is less than 0.03W/(m·K), water absorption is extremely low, usually less than 2%, and good dimensional stability , not prone to shrinkage or expansion after long-term use.
2. Thermal performance analysis : Due to the independent bubble structure inside the extruded board, these bubbles are tightly wrapped by polystyrene material, making it difficult to transfer heat. Therefore, extruded polystyrene boards have excellent thermal insulation properties and are especially suitable for building exterior walls, roofs and other occasions that require thermal insulation.
3. Mechanical strength index: XPS board is the third generation of rigid foam insulation material. It is made from polystyrene resin and other additives through the extrusion process. It has a continuous uniform surface layer and a closed-cell honeycomb structure. These thick boards with honeycomb structure are completely different. There will be gaps. This closed-cell structure insulation material can have different pressures (150-500Kpa) while having the same low value of thermal conductivity (only 0.028W/M.K) and long-lasting excellent insulation and pressure resistance properties. , the compressive strength can reach 220-500Kpa. These excellent mechanical strength indicators ensure that extruded boards can remain stable in complex and changeable natural environments.
4. Waterproof and moisture-proof performance: The extruded board itself does not absorb water, and its internal bubble structure can effectively prevent moisture penetration, so it has good waterproof and moisture-proof properties. In humid or rainy environments, extruded boards can still maintain their original thermal insulation properties and mechanical strength.
5. Environmental protection and safety: Extruded board does not use any harmful substances in the production process, and its waste can be recycled and reused. It is an environmentally friendly building material. At the same time, extruded boards do not produce toxic gases during the combustion process and comply with national fire safety standards.
6. Processing and application fields: Extruded boards are easy to cut and install, and can be closely combined with other building materials such as concrete and steel. They are widely used in building exterior wall insulation, roof insulation, ground insulation and other fields. In addition, extruded boards can also be used in cold storage, refrigerated trucks and other places where thermal insulation is required.
7. Maintenance and maintenance suggestions: To maintain good performance of extruded boards, it is recommended to conduct regular visual inspections to ensure that their surfaces are intact. If the surface is found to be damaged or stained, it should be repaired and cleaned in time. At the same time, avoid stacking heavy objects or sharp objects on the surface of the extruded board for a long time to prevent it from deforming under pressure. During construction and use, relevant specifications should be followed to ensure that the extruded panels are installed correctly and perform as they should.
