Insulation board is a key material for building insulation and heat insulation, mainly used to "put on a coat" for buildings, reducing heat exchange between the inside and outside, achieving the effect of being warm in winter and cool in summer, and saving energy.

There are many types of insulation boards available in the market, each with different materials, resulting in significant differences in performance and price. When choosing, it is important to carefully consider the following factors:

XPS extruded board: This board has high hardness and good moisture resistance, and it hardly absorbs water, making it suitable for use in cold storage or damp places. Its insulation effect is stronger than that of ordinary foam boards.

EPS polystyrene board: It is a common white foam board, which is lightweight, inexpensive, and easy to construct. However, its fire resistance is generally average, depending on the flame retardant rating.

Polyurethane board: It boasts the best insulation performance, low thermal conductivity, and fire retardancy. However, its price is relatively high, making it suitable for places with high insulation requirements.

Rock wool board: It is a non-combustible material (Class A fire-resistant), with high safety, suitable for public buildings with strict fire protection requirements, but its insulation effect will decrease after absorbing water.

Metal insulation and decoration integrated panel: This panel combines insulation and decoration. It features a metal exterior and an insulation layer inside. It is easy to install, has an attractive appearance, and is suitable for renovating old buildings. ‌‌

Insulation boards have a wide range of application scenarios, and the types used vary from place to place:

Building exterior wall: The most common type, applied to the outside of the wall to prevent heat loss, with XPS, EPS, and rock wool being widely used.

Roof and floor: XPS boards are commonly used for roof insulation due to their compressive strength and waterproofing properties; they can also be used for floor insulation to prevent cold air from penetrating upwards.

Cold storage and cold chain: They have particularly high insulation requirements, generally using polyurethane boards or thick XPS boards to ensure stable temperature.

Industrial plant: Some metal insulation boards are directly used as the enclosure of the plant, serving both as insulation and as a wall. ‌‌
