Common Types of Insulation Boards

Insulation decorative plate is easy to understand, it is a board for building insulation. It has moisture-proof and waterproof properties, which can reduce the thickness of the building's outer envelope, thereby increasing the indoor usable area. Next, let's take a look at the two common types of Insulation boards.

Here is the content list:

• XPS Insulation board

• Polyurethane Insulation board

XPS Insulation board

XPS Insulation board is a rigid foam plastic board made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, heated and mixed while injecting a catalyst, and then extruded. Its scientific name is extruded polystyrene foam for heat insulation, or XPS for short. XPS has a perfect closed-cell honeycomb structure, which allows XPS boards to have extremely low water immersion (nearly no water immersion), low thermal conductivity, high contraction resistance, and growing resistance (nearly no aging corruption in normal use).

Polyurethane Insulation board

1. Hard polyurethane Thermal insulation foam board has low thermal conductivity and good thermal performance. When the bulk density of rigid polyurethane is 35-40kg/m3, the thermal conductivity is only 0.018g-0.023w/(m.k), which is about half of EPS, and it is the lowest thermal conductivity of all insulation materials.

2. Rigid polyurethane board has moisture-proof and waterproof performance. The closed cell rate of rigid polyurethane is more than 90%, which is a hydrophobic material, which will not increase the thermal conductivity due to moisture absorption, and the wall will not seep water.

3. Hard polyurethane incombustible, honey retardant, high-temperature resistance. Polyurethane is a kind of honey retardant tone- extinguishing material after adding honey retardant. The softening point of polyurethane sequestration board can reach over 250 degrees Celsius, and it'll only putrefy at advanced temperatures. In addition, when polyurethane burns, it'll forms ash on the face of its froth. This subcaste of ash can help insulate the froth below and effectively help the spread of fire. also, polyurethane doesn't produce dangerous feasts at high temperatures.

4. Due to the excellent heat insulation performance of polyurethane boards, under the same heat preservation requirements, the thickness of the building's outer protective structure can be reduced, thereby increasing the indoor usable area.

5. Polyurethane Roof insulation board has a strong anti-deformation ability, is not easy to crack, and the finish is stable and safe.

6. The porosity structure of the polyurethane material is stable, basically a closed-cell structure, which not only has excellent thermal insulation performance but also has good freeze-thaw resistance and sound absorption. The average lifespan of the rigid polyurethane foam insulation structure can reach more than 30 years under normal use and maintenance conditions.

7. Polyurethane Insulation board is comprehensive and cost-effective. Although the unit price of rigid polyurethane foam is higher than that of other traditional insulation materials, the increased cost will be offset by the substantial reduction in heating and cooling costs.
