Blue 10-80mm XPS Insulation Board Flexible Thermal Insulation

Products Description
 
XPS is a rigid foam board manufactured by heating and mixing while injecting a catalyst, and then extrusion molding. Its scientific name is extruded polystyrene foam for heat insulation (XPS for short), and XPS has a perfect closed-cell honeycomb Structure, this structure makes XPS board have extremely low water absorption (almost no water absorption), low thermal conductivity, high compression resistance, and aging resistance (almost no aging decomposition phenomenon in normal use).
 
Application
 
Building roof insulation, steel structure roof, building wall insulation, building ground moisturizing, square ground, ground frost heave control, central air conditioning ventilation ducts, etc.

1. Thermal insulation performance:
The insulation performance of EPS and XPS with the same thickness is gradually improved. EPS is 0.041 and XPS is 0.030. Therefore, to achieve the same thermal insulation effect, the XPS board is thinner than the EPS board, but the price of the pure board is more expensive than the EPS board. If the process and the height of the building are fully considered, the price per square meter of XPS is more expensive than EPS.
For heat insulation, it mainly depends on the thermal inertia index D, and the D value is directly proportional to the heat storage coefficient. But as far as the whole system is concerned, the heat storage of 200mm concrete is large enough, and the external insulation layer can fully meet the energy-saving requirements. This is also the reason why the national code requires the comprehensive thermal conductivity and thermal storage coefficient of the wall to meet the requirements at the same time. Either EPS or XPS thin plastering systems fully meet the requirements.
 2. Strength:
The strength pointed out here should be the tensile strength. The bulk density of polystyrene board has an absolute relationship with the tensile strength. The general EPS bulk density of 18Kg/m3 has a tensile strength of 110-120KPa, and the bulk density of 20Kg/m3 is around 140KPa. The bulk density of XPS is normally from 25Kg to 45Kg, and the strength is from 150KPa to 700KPa or higher. (The premise is to meet the thermal conductivity of about 0.03).
The strength of the XPS board is 200KPa-250KPa. The XPS board of most domestic manufacturers is basically 100~200kPa, and the EPS board is below 100KPa. In the case of more and more abundant facade decorations and frequent typhoons in coastal areas, the strength appears to be very high. Important, especially for some external wall tiles or high-rise buildings, both boards need to be reinforced or fixed with fixings. The drawing of ceramic tiles must be greater than 400KPa, even XPS cannot bear it. The solution is to use expansion bolts to anchor the steel mesh to the base layer, which can disperse the tensile stress in the three-dimensional space, so as long as the anchoring is proper, the drawing damage must be compounded The anti-cracking mortar layer of steel mesh is not a big problem.

3. Weather resistance:
Weather resistance refers to the adaptability of the thermal insulation system to external weather changes, and refers to a series of quality-related issues such as the overall stability of the system and whether the thermal insulation effect changes under different climatic conditions. Weather resistance is a very important indicator of the insulation system.
Since the EPS board has higher water absorption compared with XPS, its weather resistance is not as good as the XPS system. However, the ductility of the EPS board is better than that of the XPS board, which can overcome certain defects. However, as far as the system is concerned, the plastering glue on the outer layer of the thin plastering system itself also has a certain waterproof ability. Except during the construction process, the waterproof performance of the intact two systems is acceptable. The contact between the rainwater on the outer wall and the wall surface is on the vertical surface. As long as the surface mortar does not crack, there is no problem with waterproofing.

4. Breathability:
Breathability and water absorption are two problems! The size of air molecules and water molecules is very different! Of course, there is a saying that it is breathable and impermeable. There are experiments to illustrate this point. For example, in Shenzhen. Put a biscuit out, you don't have to pour water on the biscuit, and the biscuit will soften in a day, because it absorbs water, and the water it absorbs is water in the air, not liquid water.
In the insulation system, there is no product that dares to claim that its products have good air permeability, good thermal conductivity, good waterproof performance, and no water absorption. Because these indicators are contradictory, and the breathability also needs to pay attention to the breathability after wet water during the construction process and the breathability after the system is completed.
