Purpose

1. Widely used for insulation of walls, flat concrete roofs, and steel structure roofs;
2. Used for moisture-proof and thermal insulation in areas such as low-temperature storage floors, parking platforms, airport runways, highways, etc.
Extruded board is a kind of environment-friendly thermal insulation material with high compression resistance, low water absorption, moisture-proof, airtight, light weight, corrosion resistance, super aging resistance (almost no aging after long-term use), and low thermal conductivity.
Extruded polystyrene board is widely used for insulation of dry walls, flat concrete roofs, and steel structure roofs. It is also used for moisture-proof insulation of low-temperature storage floors, low-temperature floor radiant heating pipes, parking platforms, airport runways, highways, and other fields. It controls ground frost heave and is a cost-effective and high-quality insulation and moisture-proof material in the construction industry.

Product Features

1. Has excellent and long-lasting thermal insulation properties
The goal of all insulation materials is to achieve the lowest possible thermal conductivity. Extruded polystyrene board is mainly made from polystyrene, which is already an excellent low thermal conductivity material. Combined with extrusion extrusion, the tight honeycomb structure effectively prevents heat conduction. The thermal conductivity coefficient of the energy gathering board is 0.028W/m · k, with high thermal resistance and low linear expansion rate. The thermal conductivity is much lower than other insulation materials. Such as EPS board, foamed polyurethane, insulation mortar, perlite, etc.
2. Superior water resistance and moisture resistance
Extruded polystyrene board has a tight closed cell structure, and the molecular structure of polystyrene itself does not absorb water. There are no gaps on both sides of the board, so the water absorption rate is extremely low, and the moisture and penetration resistance are excellent.
3. Corrosion resistance and durability
Ordinary hard foam insulation materials are prone to aging after several years of use, leading to a decrease in water absorption and performance. However, extruded polystyrene board has excellent anti-corrosion, anti-aging, insulation properties, and can maintain its excellent performance even under high water vapor pressure, with a service life of up to 30-40 years.
