Brushed extruded polystyrene board
- Product details
-
The brushed surface is formed through a special process, which is characterized by enhancing the contact area with the wall for easy construction, and increasing its bonding strength, making it less likely to detach from the wall. Its performance is far superior to that of the light panel, making it a better choice for wall insulation.
Excellent thermal insulation performance
It has the characteristics of high thermal resistance, low linearity, and low expansion ratio. Its structure has a closed cell rate of over 99%, forming a vacuum layer to avoid air flow and heat dissipation, ensuring the durability and stability of its insulation performance.
Excellent high-strength compressive strength:
Due to the special structure of XPS board, its compressive strength is extremely high and its impact resistance is extremely strong. Depending on the different models and thicknesses of XPS, its compressive strength can reach 150-500Kpa or more, and it can withstand various system ground loads.
High quality hydrophobicity and moisture resistance
Water absorption rate is an important parameter for measuring insulation materials. After absorbing water, the insulation performance of the insulation material decreases. At low temperatures, the absorbed water is prone to freezing, which damages the structure of the insulation material and reduces the compressive strength and insulation performance of the board. Due to the fact that the molecular structure of polystyrene itself does not absorb water, the molecular structure of the board is stable
Good stability and corrosion resistance
During long-term use, XPS extruded insulation board does not age, decompose, or produce harmful substances. Its chemical properties are extremely stable and will not degrade due to water absorption or corrosion, resulting in a decrease in its performance. It can still maintain its superior performance in high temperature environments. According to relevant information, even after 30-40 years of use, XPS extruded insulation board can maintain its superior performance
Application fields:
1. Using extruded polystyrene board as insulation layer and laying it on top of the waterproof layer can protect the waterproof layer from damage caused by temperature, ultraviolet rays, and external forces, and can also eliminate the need for a roof exhaust system;
2. Extruded polystyrene board can be used for indoor and outdoor insulation, suitable for insulation and heat preservation of interior and exterior walls of building surfaces. It can also be used in low-temperature cold storage, refrigerated trucks and other places, and has structural load-bearing effect; 3. Squeezing board is used to control ground frost heave by laying it under the pavement and roadbed of highways, railways, and runway in high-altitude and cold regions;
4. Extruded plastic boards can be used as fillers for suspended flooring. Widely applicable for filling and laying suspended flooring such as lacquered boards and composite flooring, while also serving as moisture-proof, thermal insulation, and sound insulation;
5. Extruded plastic boards can be used as permanent or temporary templates for concrete pouring and permanent templates for pipeline insulation;

common problem
Q
What are the main types of building insulation materials? What are the advantages and disadvantages of each?
A
Advantages: Good fire resistance (Class A non combustible), good breathability, and high stability.
Disadvantages: Slightly higher thermal conductivity than organic materials, higher water absorption rate, and easy generation of fiber dust during construction.
Organic insulation materials (such as EPS polystyrene board, XPS extruded board, PU polyurethane):
Advantages: low thermal conductivity, good insulation effect, light weight, and convenient construction.
Disadvantages: The fire rating is mostly B level (requiring the addition of flame retardants), it is prone to deformation at high temperatures, and its durability is slightly poor.
Composite insulation materials (such as integrated insulation board, vacuum insulation board):
Advantages: Excellent comprehensive performance, high construction efficiency, and some can achieve Class A fire protection.
Disadvantages: High cost and strict requirements for the flatness of the base layer.
Q
How to choose insulation materials suitable for the project?
A
Fire prevention requirements: Grade A materials are required for high-rise buildings (>100m); Low level B1 (flame retardant) is available.
Climate conditions: In extremely cold regions, materials with low thermal conductivity (such as PU, XPS) are preferred; Low water absorption is required in humid environment (such as XPS, foam glass).
Base type: Concrete walls often use boards; Complex shapes can be coated with polyurethane or insulated mortar.
Economy: EPS has the lowest cost; Vacuum insulation board is expensive but thin.
Policy and regulations: B2 level materials are prohibited in some areas, and local standards need to be consulted.
