Product Introduction
Extruded Insulation Board (XPS)
This product is formed by heating and melting the raw materials and then continuously extruding and expanding them. It is manufactured through a vacuum extrusion foaming method that fills the micro independent bubble structure with fluorocarbon gases.
Possesses excellent compressive strength.
Simple construction process with high insulation, corrosion resistance, and water resistance, making it suitable for all-weather use.
More expensive than bead method insulation boards and its insulation performance may decrease over time.
Exposure to sunlight or temperatures exceeding 70℃, such as from floor heating, may cause secondary expansion, leading to potential swelling or lifting of exterior materials or floors.
