Stucco Coated XPS

Huamei plastic extruded plates are serial products developed through special technique according to the requirements of exterior wall insulation system. For external insulation system for thin plaster exterior wall, there are pattern coating and stucco coating (coarse stucco and fine stucco) with both-side notches on the coating, which have the following features: easy and convenient operation, increased mortar adhesion area and enhanced adhesion strength, and all of these ensure sound stability, weather resistance and durability of the external insulation system for the exterior wall. Huamei plastic extruded plates are the best choice for exterior wall insulation system.

Product Description

Extruded Polystyrene (XPS) is a high performance rigid insulation with a closed cell structure which makes it impervious to moisture. It is a structural insulant which is available in various grades for specific applications requiring high loadings or resistance to excessive moisture levels. It is produced either as a standard construction product or a close tolerance version for panel making applications. Available in white or black, it is one of the most practical insulating materials available. It is both an insulation solution and a structural insulation solution.

General characteristics.

♦ High thermal insulation

Low electrical conductivity for energy efficiency

♦ High resistance to compression, allowing easy adhesion of the panels to walls or floors

♦ Dimensional stability with temperature and humidity

♦ Low vapour permeability

Lightweight, manoeuvrable and easy to apply, XPS can be cut with a knife without special tools and fixed with wallpaper adhesive

♦ Long lasting insulation


For concrete slabs, green roofs, edge beams, cavity walls, external walls and cool rooms.

Specifically as follows.

basements and walls.

masonry cavity walls.

floor bearing floors.

suspended concrete floors.

Partitioned floors.

underfloor heating systems.

exposed soffits.

pitched roofs.

green/paved roofs. 

Due to its high resistance to water absorption, extruded polystyrene can be used for floor insulation beneath concrete slabs and on inverted roofs where its mechanical damage caused by pedestrian traffic is an advantage. 

Polystyrene can also be laminated to tongue and groove damp-proof flooring grade chipboard, applied directly to concrete floor slabs and laminated to gypsum board as wallboard.
