Expanded polystyrene wall cladding is known for its excellent insulation properties and has become increasingly popular in modern construction. Due to its unique properties, expanded polystyrene (EPS) insulation boards are ideal for external insulation applications. Polystyrene cladding systems typically consist of several layers, 75 mm thick EPS insulation board, a base coat, reinforcement mesh, and a finish coat, designed to provide thermal insulation, enhance aesthetic appeal, and protect the building structure from external elements.
Benefits of Expanded Polystyrene Cladding
Superior Insulation
Polystyrene wall cladding provides excellent thermal insulation, reducing heat loss in winter and heat gain in summer. This results in significant energy savings and enhanced indoor comfort.
Lightweight
Polystyrene insulation boards are lightweight, making it easy to handle and install. This reduces construction time and labour costs.
Design Flexibility
The use of Polystyrene insulation boards offers a wide range of design options, including various textures, colours, and finishes. It can be customised to match the appearance of other materials such as brick, stone, or wood.
Durability
When properly installed and maintained, polystyrene insulation systems are highly durable and resistant to weathering, impact, and moisture.
Cost-Effective
The cost of materials and installation for polystyrene insulation sheets is generally lower than traditional cladding materials like brick or stone. The energy savings over time further enhance its cost-effectiveness.
Applications of Polystyrene Wall Cladding
Residential Buildings
Expanded polystyrene cladding is widely used in residential construction for both new builds and renovations. It provides excellent insulation and aesthetic versatility.
Retrofitting
Older buildings can benefit from the energy efficiency and aesthetic upgrades provided by polystyrene insulation boards. Retrofitting with EPS cladding can significantly enhance the building’s performance and curb appeal.
Wall Cladding Installation Process
1. Preparation: The building surface must be clean, dry free of debris. Any necessary repairs to the substrate should be completed before installation.
2. Application of Insulation Boards: EPS insulation boards are cut to size and adhered to the building surface using an adhesive mortar. The boards are then mechanically fastened for additional security.
3. Base Coat and Reinforcement: A base coat is applied over the insulation boards, followed by embedding a fiberglass mesh for reinforcement. This layer provides strength and resistance to cracking.
4. Finish Coat: A finish coat is applied to provide the desired texture and colour. This layer protects the insulation and enhances the building’s appearance.
EPS polystyrene cladding offers a modern, versatile, and cost-effective solution for insulating and enhancing the exterior of buildings. Its benefits in terms of energy efficiency, design flexibility, ease of installation make it an attractive option for both residential and commercial projects.
